There are important reasons why certain “ugly” animals look the way they do. Their features help them survive in the great outdoors. In this lesson students will explore their reactions to these less than lovely creatures. After observing how these animals’ unique features help them survive, students will re-visit their initial reactions to see if their perceptions of “ugly” animals have changed. Students will also design and conduct a survey to analyze whether humans’ attitudes about beauty impact animals.

Grade level: Grades 9 – 12

Uses criteria to evaluate own and others’ effectiveness in group discussions and formal presentations (e.g., accuracy, relevance, and organization of information; clarity of delivery; relationships among purpose, audience, and content; types of arguments used; effectiveness of own contributions)

4. Adjusts message wording and delivery to particular audiences and for particular purposes (e.g., to defend a position, to entertain, to inform, to persuade)

5. Makes formal presentations to the class (e.g., includes definitions for clarity; supports main ideas using anecdotes, examples, statistics, analogies, and other evidence; uses visual aids or technology, such as transparencies, slides, electronic media; cites information sources)

7. Uses a variety of verbal and nonverbal techniques for presentations (e.g., modulation of voice; varied inflection; tempo; enunciation; physical gestures; rhetorical questions; word choice, including figurative language, standard English, informal usage, technical language) and demonstrates poise and self-control while presenting

Mathematics

Standard 6. Understands and applies basic and advanced concepts of statistics and data analysis

1. Selects and uses the best method of representing and describing a set of data (e.g., scatter plot, line graph, two-way table)

Standard 9. Understands the general nature and uses of mathematics

1. Understands that mathematics is the study of any pattern or relationship, but natural science is the study of those patterns that are relevant to the observable world

4. Understands that theories in mathematics are greatly influenced by practical issues; real-world problems sometimes result in new mathematical theories and pure mathematical theories sometimes have highly practical applications

Life Sciences

Standard 6. Understands relationships among organisms and their physical environment

1.

Introductory Activity

The purpose of this activity is for students to analyze their concepts of beauty.

Time for completion: 15 minutes

1. Pass out the “True Beauty” organizer. Ask students to write a personal definition of the words “ugly” and “beautiful” in their organizers. After students have completed writing their definitions, have them share and discuss the commonalities and differences of their responses. Students will be using the “True Beauty” organizer in Activity One.

Steps

Activity One

The purpose of this activity is for students to examine how the beauty, or lack of beauty, in an animal impacts their perception of that animal.

Time for completion: One 50-minute class

In preparation for this activity, gather together the following materials:

• Five photographs of “ugly” animals glued onto 4×4 cards. These photographs should include images of the star-nosed mole, alligator snapping turtle, adjutant stock, proboscis monkey and naked mole-rat.
• Five photographs of “beautiful” animals such as baby harbor seals, male peacocks, swans, etc., glued onto 4×4 cards. The Nature website may be a good source for these images
• A set of two smiley face images glued or drawn onto 4×4 cards
• A set of two frowning face images glued or drawn onto 4×4 cards You may make multiple sets so that all the students may complete this activity at the same time, or make one set and have students take turns.

1. Divide the class into pairs. Give one person a smiley face card, a frowning face card and the set of ten animal photographs. Make sure that the cards are well shuffled. Instruct them not to show the photographs to their partner until they are ready to begin, and to place the smiley face and frowning face cards face up on the table in front of them. Give the second person in the pair a smiley face card and a frowning card. Tell them to hold one card in each hand.
2. Tell students that they are going to be shown a photograph of an animal, and when they see the photograph, they will hold up either the smiley face or the frowning face based on their reaction to the photograph. After their partner has held up the smiling or frowning face card, instruct the student holding the animal cards to place the card beside the smiling or frowning face, based upon which card their partner held up. In other words, if the student shows their partner a photograph of a baby harbor seal and the partner holds up a smiley card, they will then place the photograph of the seal beside the smiley face card.
3. Ask students to continue in the same manner until all of the animal cards have been used. Tell students that they should go through the picture cards as quickly as possible. Students should give an instant response to the animal image. After students have finished, ask them to write down the names of the animals that were placed in each category in their “True Beauty” organizers. Tell students to switch places and repeat the activity.
4. After students have finished, ask them to share the results in a whole-class discussion. Ask students to draw some conclusions as to how they perceive beauty in animals.
5. View the clips from “The Beauty of the Ugly” program that feature the “ugly” animals on the cards. Ask students to record in their “True Beauty” organizers an explanation of how these features that may be considered unattractive in these animals actually help them to survive.
6. Have students repeat the animal photograph activity a second time. Record the results in the “True Beauty” organizer. Ask students to respond in writing to the last question in the organizer.

Activity Two

Time for completion: Three – 50 minute class periods and several homework assignments

In this activity, students will create a survey to draw conclusions about people’s attitudes toward ugly animals. They will design a survey, analyze the data from the survey, create graphs and present their findings to the class.

1. Watch “The Beauty of Ugly” program from 05:20 to 06:52. Call attention to the last line, “But we’re a lot harder on animals that don’t conform to our ideal of physical perfection.” Ask students if they think this attitude has an impact on the average person’s desire to preserve and protect “ugly” animals versus people’s desire to protect and preserve more attractive animals. Tell the students that they are going to design a survey to investigate whether there are any differences in people’s desire to protect the health and safety of “ugly” animals versus “beautiful” animals.
2. Divide the class into small groups. Pass out and review the “Do Humans’ Attitudes about Beauty Impact Animals?” survey organizer and the “Survey Presentation” rubric.The websites listed below contain helpful information on creating and analyzing a survey. Depending on your students’ ability level, you may choose to review the information as a class, or have the individual groups refer to them as needed.

GRADE LEVEL: 9-12

TIME ALLOTMENT: Three 45-minute class periods

OVERVIEW: The traditional view of animal behavior is that it is driven by inherited, innate instincts, but recent scientific research is revealing a larger role for complex cognitive processes among many species. The lesson will explore some of the more commonly accepted indicators of animal intelligence as demonstrated by the most brainy of all birds-the raven.

Students will first explore a series of science Web sites to compile a list of certain animal behaviors and abilities that indicate higher intelligence. They will then find and analyze examples of these behaviors and abilities as demonstrated by ravens in selected clips from the NATURE episode “Ravens.” Based on what they learn, students will then work in groups to create a theoretical intelligence-challenging “obstacle course” for ravens.

This lesson could be used following (or in conjunction with) the lesson “Symbiotic Strategies.”

SUBJECT MATTER: Living Environment/Biology

LEARNING OBJECTIVES:

Students will be able to:

• Compare “classical” and “modern” views of bird brain anatomy and function, and compare bird brains to human brains;
• Describe various raven behaviors and abilities that indicate intelligence;
• Explain why many of these behaviors indicate cognitive intelligence rather than simple inherited instinct;
• Assemble a realistic sequence of intelligence-testing challenges for ravens.

STANDARDS AND CURRICULUM ALIGNMENT:

National Science Education Standards

CONTENT STANDARD C: As a result of their activities in grades 9-12, all students should develop understanding of:

THE INTERDEPENDENCE OF ORGANISMS

• Organisms both cooperate and compete in ecosystems. The interrelationships and interdependencies of these organisms may generate ecosystems that are stable for hundreds or thousands of years.
• Living organisms have the capacity to produce populations of infinite size, but environments and resources are finite. This fundamental tension has profound effects on the interactions between organisms.

THE BEHAVIOR OF ORGANISMS

• Organisms have behavioral responses to internal changes and to external stimuli. Responses to external stimuli can result from interactions with the organism’s own species and others, as well as environmental changes; these responses either can be innate or learned. The broad patterns of behavior exhibited by animals have evolved to ensure reproductive success. Animals often live in unpredictable environments, and so their behavior must be flexible enough to deal with uncertainty and change. Plants also respond to stimuli.
• Like other aspects of an organism’s biology, behaviors have evolved through natural selection. Behaviors often have an adaptive logic when viewed in terms of evolutionary principles.
• Behavioral biology has implications for humans, as it provides links to psychology, sociology, and anthropology.

CONTENT STANDARD G: As a result of activities in grades 9-12, all students should develop understanding of

NATURE OF SCIENTIFIC KNOWLEDGE

• Scientific explanations must meet certain criteria. First and foremost, they must be consistent with experimental and observational evidence about nature, and must make accurate predictions, when appropriate, about systems being studied. They should also be logical, respect the rules of evidence, be open to criticism, report methods and procedures, and make knowledge public. Explanations on how the natural world changes based on myths, personal beliefs, religious values, mystical inspiration, superstition, or authority may be personally useful and socially relevant, but they are not scientific.
• Because all scientific ideas depend on experimental and observational confirmation, all scientific knowledge is, in principle, subject to change as new evidence becomes available. The core ideas of science such as the conservation of energy or the laws of motion have been subjected to a wide variety of confirmations and are therefore unlikely to change in the areas in which they have been tested. In areas where data or understanding are incomplete, such as the details of human evolution or questions surrounding global warming, new data may well lead to changes in current ideas or resolve current conflicts. In situations where information is still fragmentary, it is normal for scientific ideas to be incomplete, but this is also where the opportunity for making advances may be greatest.

GRADE LEVEL: Grades 9-10

TIME ALLOTMENT: Two to three 45-minute class periods

OVERVIEW: The structure of an organism is related to its function and the role it plays in its environment. Many structural differences can be found within a species. These structural differences are often adaptations that allow organisms to better survive in their particular environment. These evolutionary adaptations develop through the process of natural selection.

This lesson explores different adaptations and variations in birds, using the NATURE episode “Extraordinary Birds.” It focuses on bird beaks, migratory patterns, and birds’ ability to co-exist with humans. Students will define key concepts from the lesson, discuss and explore different adaptations of birds, and analyze relationships between the concepts learned. This lesson can be taught independently, or it can be used as a precursor to the New York State Core Curriculum “Beaks of Finches” lab. Students must have a basic knowledge of evolution and natural selection in order to successfully complete this lesson.

SUBJECT MATTER: Biology/ Living Environment

LEARNING OBJECTIVES:

Students will be able to:

• Discuss and define key concepts from the lesson, including adaptation, migration, and interaction between humans and birds;
• Describe how particular characteristics of bird beaks reflect birds’ adaptations to their particular environments;
• Explain how different environmental factors can affect the migration cycle of the Rufous Hummingbird;
• Demonstrate understanding of how adaptations in different species of birds assist their interactions with humans;
• Create a concept map using different adaptive traits of birds.

GRADE LEVEL: 9-12

TIME ALLOTMENT: Two 45 minute classes

OVERVIEW: This lesson discusses the processes of weathering and erosion and how they work together to shape the earth’s landscape. An online game introduces students to the basic modes of erosion. The processes of chemical and physical weathering that enable erosion are then explored in detail using online media and hands-on laboratory experiments. Next, video clips from the NATURE episode “Violent Hawaii” are used to revisit in greater detail the causes and effects of erosion in the real world, and human attempts to limit it. The lesson culminates with an online game that reinforces students’ understanding of the lesson’s vocabulary and concepts.

SUBJECT MATTER: Geology/Earth Science

LEARNING OBJECTIVES:

Students will be able to:

• Differentiate and describe the processes of weathering and erosion
• Differentiate and describe the processes of mechanical and chemical weathering
• Model the process of mechanical and chemical weathering, drawing conclusions from their results
• Determine which environments and climates are most likely to promote different types of weathering and erosion
• Describe various human attempts to limit erosion

STANDARDS AND CURRICULUM ALIGNMENT:

National Science Education Standards

CONTENT STANDARD D: Geochemical cycle

All students should develop an understanding of:

GEOCHEMICAL CYCLES

• The earth is a system containing essentially a fixed amount of each stable chemical atom or element. Each element can exist in several different chemical reservoirs. Each element on earth moves among reservoirs in the solid earth, oceans, atmosphere, and organisms as part of geochemical cycles.
• Movement of matter between reservoirs is driven by the earth’s internal and external sources of energy. These movements are often accompanied by a change in the physical and chemical properties of the matter. Carbon, for example, occurs in carbonate rocks such as limestone, in the atmosphere as carbon dioxide gas, in water as dissolved carbon dioxide, and in all organisms as complex molecules that control the chemistry of life.

New York State Regents Core Curriculum Alignments:

Physical Setting: Earth Science Core Curriculum

STANDARD 1: Students will use mathematical analysis, scientific inquiry, and engineering design, as appropriate, to pose questions, seek answers, and develop solutions.

Key Idea 1: The central purpose of scientific inquiry is to develop explanations of natural phenomena in a continuing, creative process.

Key Idea 2: Beyond the use of reasoning and consensus, scientific inquiry involves the testing of proposed explanations involving the use of conventional techniques and procedures and usually requiring considerable ingenuity.

Key Idea 3: The observations made while testing proposed explanations, when analyzed using conventional and invented methods, provide new insights into phenomena.

STANDARD 2: Students will access, generate, process, and transfer information, using appropriate technologies.

Key Idea 1: Information technology is used to retrieve, process, and communicate information as a tool to enhance learning.

STANDARD 4: Students will understand and apply scientific concepts, principles, and theories pertaining to the physical setting and living environment and recognize the historical development of ideas in science.

Key Idea 2: Many of the phenomena that we observe on Earth involve interactions among components of air, water, and land.

Performance Indicator 2.1p: Landforms are the result of the interaction of tectonic forces and the processes of weathering, erosion, and deposition.

Performance Indicator 2.1s: Weathering is the physical and chemical breakdown of rocks at or near Earth’s surface. Soils are the result of weathering and biological activity over long periods of time.

Performance Indicator 2.1t Natural agents of erosion, generally driven by gravity, remove, transport, and deposit weathered rock particles. Each agent of erosion produces distinctive changes in the material that it transports and creates characteristic surface features and landscapes. In certain erosional situations, loss of property, personal injury, and loss of life can be reduced by effective emergency preparedness.

Performance Indicator 2.1u The natural agents of erosion include:

-Streams (running water): Gradient, discharge, and channel shape influence a stream’s velocity and the erosion and deposition of sediments. Sediments transported by streams tend to become rounded as a result of abrasion. Stream features include V-shaped valleys, deltas, flood plains, and meanders. A watershed is the area drained by a stream and its tributaries.

- Glaciers (moving ice): Glacial erosional processes include the formation of

U-shaped valleys, parallel scratches, and grooves in bedrock. Glacial features include moraines, drumlins, kettle lakes, finger lakes, and outwash plains.

- Wave Action: Erosion and deposition cause changes in shoreline features, including beaches, sandbars, and barrier islands. Wave action rounds sediments as a result of abrasion. Waves approaching a shoreline move sand parallel to the shore within the zone of breaking waves.

-Wind: Erosion of sediments by wind is most common in arid climates and along shorelines. Wind-generated features include dunes and sand-blasted bedrock.

-Mass Movement: Earth materials move downslope under the influence of gravity.

Performance Indicator 2.1v Patterns of deposition result from a loss of energy within the transporting system and are influenced by the size, shape, and density of the transported particles. Sediment deposits may be sorted or unsorted.

Performance Indicator 2.1w Sediments of inorganic and organic origin often accumulate in depositional environments. Sedimentary rocks form when sediments are compacted and/or cemented after burial or as the result of chemical precipitation from seawater.

STANDARD 6: Students will understand the relationships and common themes that connect mathematics, science, and technology and apply the themes to these and other areas of learning.

Key Idea 1: Through systems thinking, people can recognize the commonalities that exist among all systems and how parts of a system interrelate and combine to perform specific functions.

GRADE LEVEL: 2 -3

TIME ALLOTMENT: One to two 45-minute class periods

OVERVIEW:

Students learn that living things experience diverse life cycles. For example, baby birds go through distinct stages as they grow up into adult birds. This lesson uses the eagle to model universal avian life stages: from egg, to chick, to fledgling juvenile, to adult.

Students begin by creating a collage of bird images, discussing the characteristics that all birds share. A well-known story, The Ugly Duckling, is then read to introduce the concept of change over the life span. Students then use segments from the NATURE film American Eagle to learn how eagles look and act in different stages of their life cycle. At the conclusion of the lesson, students diagram the eagle life cycle, and may enhance their science learning with vocabulary and math activities.

SUBJECT MATTER:

Science, Language Arts

LEARNING OBJECTIVES:

Students will be able to:

• Describe the characteristics of birds;
• Understand that different kinds of birds display a wide variety of similarities and differences;
• Identify the stages in the life cycle of birds;
• Understand vocabulary associated with the life cycle of birds;
• Diagram the life cycle of the American Bald Eagle.

STANDARDS:

From the National Science Standards for Science Content, Grades K-4.

CONTENT STANDARD C: Life Science
As a result of activities in grades K-4, all students should develop understanding of:

LIFE CYCLES OF ORGANISMS

• Plants and animals have life cycles that include being born, developing into adults, reproducing, and eventually dying. The details of this life cycle are different for different organisms.
• Plants and animals closely resemble their parents.
• Many characteristics of an organism are inherited from the parents of the organism, but other characteristics result from an individual’s interactions with the environment. Inherited characteristics include the color of flowers and the number of limbs of an animal. Other features, such as the ability to ride a bicycle, are learned through interactions with the environment and cannot be passed on to the next generation.

GRADE LEVEL: 9-11

TIME ALLOTMENT: Three 45-minute periods

OVERVIEW: This inquiry-based lesson plan will challenge students to design and conduct scientifically valid experiments to evaluate hypotheses regarding an animal’s expected behavior in response to changes in its environment.

Students will first view and analyze video segments from the NATURE film “Earth Navigators” as they begin to think about animal behavior as a response to stimulus in the environment. The video clips feature many different animal species reacting to changes in the environment by migrating from one part of the earth to another. Students will predict the reasons for these migrations and will determine the stimuli that actually trigger the animals to migrate.

Following the video exploration, students will conduct reading and research to learn about isopods (commonly known as pill bugs or roly polies). The students will use the information they gather to formulate research questions having to do with the isopods’ expected response to environmental stimulus. The students will design experiments that can be conducted in the classroom to test their hypotheses. They will conduct the student-designed experiments, collecting data and reporting their findings and conclusions. They will also make suggestions for future improvements in the experimental protocol.

SUBJECT MATTER: Living Environment/Biology

LEARNING OBJECTIVES:

Students will be able to:

• Draw connections between the migratory behavior of different animals and seasonal changes on Earth;
• Describe migration as an instance of behavioral response to stimulus;
• Using anatomical and environmental information, create a research question about an isopod’s behavior in response to environmental stimulus;
• Create a hypothesis that addresses the research question;
• Design and conduct an experiment to evaluate the hypothesis;
• Collect data from the experiment, describe results, and evaluate conclusions.

STANDARD 1: Students will use mathematical analysis, scientific inquiry, and engineering designs, as appropriate, to pose questions, seek answers, and develop solutions

Key Idea 2: Beyond the use of reasoning and consensus, scientific inquiry involves the testing of proposed explanations involving the use of conventional techniques and procedures and usually requiring considerable ingenuity.

Performance Indicator 2.1: Devise ways of making observations to test proposed explanations.

Performance Indicator 2.3: Develop and present proposals including formal hypotheses to test explanations; i.e., predict what should be observed under specific conditions if the explanation is true.

Performance Indicator 2.4: Carry out a research plan for testing explanations, including selecting and developing techniques, acquiring and building apparatus, and recording observations as necessary.

Key Idea 3: The observations made while testing proposed explanations, when analyzed using conventional and invented methods, provide new insights into natural phenomena.

Performance Indicator 3.1: Use various methods of representing and organizing observations (e.g., diagrams, tables, charts, graphs, equations, matrices) and insightfully interpret the organized data.

STANDARD 4: Students will understand and apply scientific principles and theories pertaining to the physical setting and living environment and recognize the historical development of ideas in science.

Key Idea 5: Organisms maintain a dynamic equilibrium that sustains life.

Performance Indicator 5.3: Relate processes at the system level to the cellular level in order to explain dynamic equilibrium in multicelled organisms.

5.3a Dynamic equilibrium results from detection of and response to stimuli. Organisms detect and respond to change in a variety of ways both at the cellular level and at the organismal level.

Key Idea 6: Plants and animals depend on each other and their physical environment.

Performance Indicator 6.1: Explain factors that limit growth of individuals and populations.

6.1f Living organisms have the capacity to produce populations of unlimited size, but environments and resources are finite. This has profound effects on the interactions between organisms.

2. Ask each small group to prepare a statement that summarizes its opinions based on research and discussion.

3. As a class, decide on the format of the news broadcast. The only requirement is that each group of students should have the opportunity to present their opinions. This might be done as a series of interviews based on each small group’s research, as a debate, as a story, or in any other appropriate format that the class decides upon.

4. Stage the mock news broadcast. Invite other classes to the performance, and, if possible, videotape it.

5. After the presentation, allow time for discussion and questions.

6. Ask the students to respond to the following questions:

• Did you change your opinions after listening to the varied viewpoints?
• If so, what was the most compelling argument that made you change your views?

Activity Two

The purpose of this activity is to explore Ginger Kathrens’ experiences with wildlife photography and filmmaking.

1. Choose a student to read the following selections from the film aloud to the class:

• The violent clash of wild stallions … battling to win mares.
• Into this vibrant, perilous world a fragile colt was born.
• Though frail at first … he soon revealed his strong, funny, precocious personality.
• He grew up in a Montana wilderness of danger and excitement.
• I watched him develop into a feisty adolescent … and agonized with him when his freedom was threatened.
• In his rugged citadel, I searched for him through the seasons of his life.
• I rooted for him like a proud parent as he fought to start his own family.
• Unique, daring, and resilient … he is a wild horse of dreams, a legend in the making.
• I came into their world with a camera and intense curiosity. How do they live and survive? Will they let me get near them? Little by little they start to ignore me. That’s more than I could have ever hoped for. I can’t help coming back again and again to learn more about them.

2. Divide the class into small groups for discussions based on the following questions:

• What do you think of the filmmaker’s mission?
• What do you think of the career of wildlife photography? What do you think the challenges and rewards of this career might be?
• Why do you think she chose to do this film?
• How would you describe her relationship with Cloud and the other horses?
• How did the horses remind you of humans?
• Could you see yourself as a wildlife photographer? Why or why not?
• What do you think she really learned from making this documentary?
• What did you learn from watching this?

3. Ask each group to create a response that reflects the key points of their discussion. This might consist of a poster, a summary, a poem, or a drawing.

4. Each group should share its work with the entire class.

Activity Three

The purpose of this activity is for students to learn about animal behavior.

1. As a class, visit the following Web site that describes horse behavior at http://www.horse-behavior.com.

2. Divide the class into small groups to research different aspects of horse behavior. Tell the students that they are going to create a presentation suitable for teaching an elementary school class about the behavior of horses. They should create teaching tools, such as posters, drawings, games, etc., to enhance their presentations. Some good topics to research include the following:

• Instinct
• Communication
• Care of the Young
• Age
• How did the horses remind you of humans?
• Could you see yourself as a wildlife photographer? Why or why not?
• What do you think she really learned from making this documentary?
• What did you learn from watching this?

3. Have the students conduct a class to teach the younger students what they have learned.

4. Provide an opportunity for the younger students to respond to the presentation.

5. After the presentation, ask the students to critique their effectiveness and discuss what they did well and what they might have done differently.

Activity Four

The purpose of this activity is to provide students with opportunities to respond to the story of Cloud in different ways.

1. Divide the class into pairs. Tell the students to choose one of the following options.

• Create a story map based on Cloud’s life.
• Pretend that you are Ginger Kathrens’ assistant. Write a journal entry that describes your experiences.
• Tell the story of Cloud through a drawing or a painting.
• Create a music video based on Cloud’s life.

2. Present the students’ work to the entire class.

Extension Activities

1. Ask the students to choose three books about horses to read. Have the students share what they have learned with other students by creating an annotated bibliography or posting comments on a Web site. A great resource to use may be found at http://www.lfpl.org/kidspages/booklists/picturing_horses.htm.

2. Create a class mural depicting the history of horses. Use the following Web sites as an information source to begin researching:

• http://www.returntofreedom.org/index.htm
• http://users.erols.com/mmaidens/
• http://www.savewildhorses.org/history.htm
• http://www.pbs.org/wildhorses/wh_origin/wh_origin_intro.html
• http://www.imh.org/imh/kyhpl1b.html

In this lesson, students use a problem-based approach to explore the possibility that the qualities of different horse breeds — strength, speed, agility, stamina, beauty, intelligence, disposition — could be incorporated to create the “perfect horse,” one that would excel in all the activities and competitions involving horse and rider. Students watch Horse and Rider, and working in teams, conduct an investigation of the horse, its biology, domestication, the attributes of different breeds, their uses, and history. 

Subject: Language Arts, Science, Social Studies
Grade Level: 9-12 

LEARNING OBJECTIVES 

Students will be able to:

• Recognize and describe the unique relationship between horse and rider, and the reasons why different horse breeds were developed.
• Perform online research to learn about horse biology and behavior, the different breeds of horses, where they are found, their attributes and how and why they were developed.
• Analyze findings from the research to determine how it is possible to produce an all-purpose horse and whether it is possible or impractical. 
• Present findings in a display presentation to the class.
• Present their positions in a position paper.

STEPS

Introductory Activity 
(one to two class periods)

1. Write the following descriptions based on information from the Thirteen/WNET New York program HORSE AND RIDER on a sheet of chart paper and display it in front of the classroom. DON’T reveal the name of the animal:

• A creature of flight — its main defense, but it is also brave 
  
• A herd animal, it performs best when it’s with others of its kind
• Works in partnership with man and they form a two-person herd
• Often, the animal is the leader in the partnership
• It is intelligent and curious
• It is a high performance animal
• It is strong, but sometimes prone to injury

Ask the students “What is this mystery animal”? Give the students the opportunity to guess. If they need further help, ask them these questions:

• What would we consider to be “high performance” in an animal? 
  
• Which domesticated animal forms a true working partnership with humans, rather than a dominant-submissive relationship? How can something lead as well as be a partner?
• How can an animal be strong, but prone to injury at the same time? Would human athletes fit that description?

2. Once students have determined that the animal in question is a horse, ask them to tell the class what they know about horses — what they’ve read, seen or heard. Students may have had some personal experience with horses, and a few might be experienced riders. Have the students describe what they think the horse was like before they were domesticated and how and why humans first came to ride them. Have them list all the uses of horses by humans and why they are especially suited for these uses. Ask them whether all horses are the same or whether they are different depending on their uses. They might know of some famous examples — the giant Clydesdale horses, thoroughbreds, show horses, polo ponies. Suggest to the class some of the activities horses are used for, and ask them to describe the kinds of horses they think might be involved in those activities, whether by name or by description.


Learning Activities 

Activity 1: 
(one class period)

1. Elicit from the class the qualities of the horse that have made its partnership with humans unique in the natural world. How did those qualities evolve? Did they evolve naturally, or were they bred into them? The horse brings to the partnership traits which it acquired when it evolved as a herd animal on the plains, pursued by predators — intelligence, speed, strength, stamina and cooperative behavior, as well as a wariness and sensitivity. Over time, humans learned to work with these traits. Societies developed different breeds or varieties of horses for different uses, each one having special qualities to perform its task.

As a motivational activity, show photographs, stories, art and video from the following sites:

Click on the video clip.

2. Ask the students again to list all the different activities involving horse and rider that they can think of. Next to each particular activity, have them list the particular traits the horse must have in order to be successful in each activity. Include types such as racehorse, show horse, workhorse, sport competition horse (polo, cutting horse, rodeo), categories they will see in the program. Then ask them to list what traits the successful rider must have for each. Discuss with students afterward if there are similarities and differences between the traits valued in the different activities. Pose the problem to the students: Is it possible to produce the “perfect horse,” one that would possess all the traits that riders value, and excel in all the activities requiring horse and rider? Tell them that they will conduct research to solve this problem and then present their “perfect horses” to the rest of the class. 

Activity 2: 
(five class periods) 

1. Tell students that they are going to watch a video entitled Horse and Rider from Thirteen’s NATURE series. Explain that in the program, they will learn about three competitive activities involving horse and rider: cutting horse, dressage, and polo. If necessary, explain the three different horse-related activities they will see. Have the students make up a table. One column lists the horse activity. The second column is entitled “Horse Qualities,” in which students list the traits that the horse should possess for that particular activity. The third column should be entitled “Rider Qualities” and list how the rider should approach the particular tasks. Encourage students to discuss similarities and differences between the different sports and how this might be reflected in the horses and the riders. Would each be very different? Would one type be very similar to another? Would the riders have very different or similar philosophies about their relationships with their horses? Before watching the video, the students divide up into teams of 4 and decide which aspect of horsemanship they are interested in — racing, sport competition, show horse or work horse, or any category that may have come up in the previous activities. Each student will decide which area interests them most and will research the types of horses and their histories. Students then watch the program while taking notes in the Horse and Rider Organizer.

2. After viewing the program, the students will return to the table they made up and compare/contrast the requirements they listed with those they heard about or observed in the film. Were there more or fewer similarities among the requirements than they expected? Were some requirements promoted at the expense of others? Did the horses look different? Was the approach of the riders/trainers similar, different, or about the same? In their research, each student should learn about horses in general and about the different horse breeds from different perspectives — biological, historical, cultural, economic, geographical. They should note the strengths and weaknesses of each breed, and should keep in mind the question posed as they do their research. They should use the Horse Breed Facts Organizer to assist them. The following sites will be useful in their research:

• The Haynet: Breeds and Associations 
  http://www.haynet.net/Breeds_and_Associations/
  
• Breeds of Livestock: Horse Breeds 
  http://www.ansi.okstate.edu/breeds/horses 
  
• The American Livestock Breeds Conservancy: Horses 
  http://albc-usa.org 
  
• Horsefun

• National Show Horse Registry 
  http://www.nshregistry.org/ 
  
• National Horsetraders 
  http://www.nationalhorsetraders.com/    

   

As part of the investigation, have teams (not individual students) contact horse breeders by email to get firsthand, primary source information on what breeding, developing, and promoting different kinds of horses involves. Lists of breeders can be found through http://www.nationalhorsetraders.com and through links provided in the other listed Web sites. Contact a few breeders yourself (in advance) and ask them whether students may email them questions; then, provide students with the breeders’ contact information. 

Allow time for students in each team to share what they learned with the rest of the team. Circulate among the teams, listening to each team’s conversation. Make sure that all students are contributing to the discussion, and encourage students to listen carefully as their teammates describe the different features and backgrounds of their horses. After they pool their research, encourage students to think about how 1) what they learned about the horse’s physical features, behavior, and other characteristics and 2) the ways in which they are used by humans would make it easier or more difficult to bring these different features to a single breed of horse. Use these questions to get them started:

• How easy or difficult would it be to bring the different horses together in a ranch operation?
• Does selective breeding always bring about the desired results?
• Would all the different users of horses readily accept an all-purpose horse? Some might have strict requirements about the horse’s background.

Have the students use The Perfect Horse Organizer to pool their ideas.

Culminating Activities/Assessment:

Activity 1: 
(two class periods) 

1. Teams prepare their presentations, using their research to describe which horses they would use to create the perfect horse. Students then create a graphic, artistic flowchart on presentation board with charts, photos of the different breeds of horses, an illustration of the perfect horse, background descriptions, and distinguishing characteristics; they should also include a description of what would be involved in bringing the different breeds together. Students who are familiar with digital imaging software such as Photoshop may want to produce a digital image of the perfect horse, created by digitally blending features from the selected horses.

2. Each team then gives a presentation of their perfect horse, walking the class through their flowchart and explaining how they came to their conclusions. Allow time after each presentation for question/answer sessions, during which teams can further explain and defend their work. When all the presentations are complete, the issue of whether a perfect horse is possible or worthwhile to develop may be also discussed.

Activity 2: 
(two class periods) 

1. Continue the discussion about whether creating a perfect horse is possible and worthwhile. Invite students to reconsider how they would go about creating the perfect horse and whether this is a worthwhile endeavor. Acknowledge that it is okay if students’ initial thoughts have changed.

2. For homework, instruct students to write a position paper explaining and defending their point of view. The paper should clearly state a position and be supported by factual details from their research.

Extension Activities

• Take a class poll to find out whether it is worthwhile to create the perfect horse or if the task is too difficult. Chart the findings in a bar graph.
• Create a large life-size drawing or painting of the perfect horse, displaying the characters which it acquired from the different breeds and with bubble notes indicating the benefits that these traits bring.
• Create a poster of a favorite kind of horse; include photos and stories about its history and the culture that produced it.
• Write the story starter “If I owned a horse … ” on the chalkboard. Invite students to use what they learned to create a story or a poem.
• Visit a horse ranch and talk to the trainers about their horses and how they work with them.
• Explore how genetic engineering, as it is being used to alter domesticated plants and animals, might be applicable in producing the perfect horse

Overview

Rainforests are among the most challenging places for scientists to explore. Nevertheless, in search of answers, some intrepid scientists and researchers venture into the jungle with the latest technological devices.

Grade level: Grades 5 – 8

Subject areas: Science, Science and Technology

Learning objectives:
Students will be able to do the following:

• Observe unusual plant and animal species that exist in the world’s rainforests.
• Discuss how biologists use infrared cameras and other technology to explore jungles.

Program Highlights

• Creating 3-D maps of the rainforests of Borneo involves a combination of daring athleticism and computer expertise. Biologist Roman Dial often works 150 feet above the ground for days at a time, using lasers to measure and map the forest. His maps show how the jungle’s complex ecosystems work.
• Tigers were once plentiful throughout Sumatra. Today, only about 500 survive in the wild. Naturalist Jeremy Holden and cameraman Gavin Thurston attempt to be the first to catch one of these elusive animals on video, setting up motion-sensitive cameras that activate when an animal passes in front of an infrared beam.
• In 1862, Charles Darwin studied a bizarre orchid found on Madagascar. Darwin predicted that its survival probably depended on a gigantic moth with a 12-inch tongue. In this program, biologist Phil DeVries uses an infrared camera to finally catch this strange insect in action.

Before Viewing the Program

Ask students to describe what a jungle is. Explain that jungles are also known as rainforests. Using a physical map of the world that identifies forests in green, ask students if they can find where the world’s jungles are located. Mention that there are many jungles around the world, and they all tend to have similar climates. Show five different photographs of animals found in the Amazon rainforest. (You can find these in library books or Web sites, such as: www.junglephotos.com). Ask students to discuss what kind of climate these creatures would need to survive. To help orient them for the first segment of the program, have students find the island of Borneo in Southeast Asia. Encourage students to pay special attention to the different technologies that help the scientists do research in the rainforest.

Discussion Questions

• Why do you think there is so much variety of life in the world’s rainforests?
• Infrared cameras use an unseen portion of the spectrum and often show differences in temperature. What are some advantages of using an infrared camera to explore a jungle?
• What are the benefits of using a laser measurement device to map a rainforest?
• Imagine that you wanted to create a 3-D map of a square mile of forest. What challenges do you think you’d face?
• If you could tag along with one of the naturalist/explorers in this program, whom would you select, and why?

Follow Up

• Use a laser pointer to highlight images in the video or related illustrations you have posted on your bulletin board. Please remind students that lasers can be dangerous if they are pointed at people’s eyes!
• Liquid crystal technology, like an infrared camera, shows different temperatures as different colors. Use a liquid crystal thermometer to map the temperature of different areas on your skin. Which is warmer, your hands or your face?
• Use the Internet to research laser measurement, infrared cameras, infrared remote control devices, remote tracking devices, or other technologies mentioned in the program.

Fun Fact

The territory of a single Sumatran tiger is about half the size of New York City.

This Teacher’s Guide accompanies the NATURE miniseries, Dogs That Changed the World. The series explores the 15,000-year-old relationship between dogs and humans and the evolution of wolves into the wide variety of dogs we know today. Dogs That Changed the World will help you and your class understand how these animals have helped shape the world we live in. Lessons in the guide use the programs as a starting point for discussions about the domestication of dogs, breeding dogs for specific traits, and the unique ways in which humans and dogs work and live together. This guide includes teacher’s pages and student activity masters that can be used with any or all of the programs. Please photocopy the pages and hand them out to students in class.
