In a recent episode of Sid, our favorite science kid wonders, "How did my dog DO that?" Philbert can move his body and get himself into positions that Sid can't, no matter how hard he tries. And try Sid does, but no dice. Or in this case, no scratching behind his ear with his foot!
Most children are fascinated by animals - their babies, the ways they move, where they live, what and how they eat, and their unique, non-human behaviors and characteristics. Teachers can use this fascination as a way to introduce all kinds of science and math ideas.
One of my favorite anecdotes from my years (lots of them now!) as a science lady comes from the Douglass Psychology Child Study Center at Rutgers. After an investigation of their own senses and those of different animals, the kids became deeply interested in snakes so off I went to the library to pick up some books. Reading about snakes, the children were extremely excited by two facts: 1. Instead of using venom or constriction, the indigo snake stuns its prey by picking it up and flinging it against a rock (ouch!), and 2. The reticulated python can grow to be 32 feet long.
Even though it's one of our show's guiding principles that science is so much more than a collection of facts, the fact of the matter is, an interesting tidbit can spark attention and draw learners into deeper, more meaningful investigations. In the case of that reticulated python, the children's enthusiasm about a 32-foot long snake - they knew it was big but not exactly HOW big - led us out to the playground and into an exploration of measurement.
Off we went with foot-long rulers and a tape measure, ready to measure out 32 feet. We marked a line with chalk, started rolling out the tape measure from there, counting feet as we rolled, one, two, three, four...As we went along the numbers got larger, but the number of children attending got smaller as kids began wandering away. This left me wondering what I could do to rekindle their initial excitement. I mean, really, we're talking about a 32-foot long snake, and I'd somehow managed to lose their interest! Switching gears, I asked for a volunteer and had him lie down, feet on the starting line. Then another child laid down feet near the first child's head. Our wanderers started coming back. What was going on? Kids were lying down on the pavement! Why? That's worth coming back and investigating!
As children lay down end-to-end, giggling all the while, the adults measured out 32 feet. It turns out, 32 feet is equal to about 9 preschoolers which means that a reticulated python is 9 kids long! As great as this activity turned out to be, the best part was when the kids went back inside and asked me to measure out 8 feet so that they could figure out how many Lincoln Logs long an indigo snake is. This continued interest in a new problem and the transfer of knowledge and application of skills to a new situation is a highly gratifying experience for a teacher. Sure was for me!
Years later, I was introduced to Steve Jenkins's book, Actual Size (also available in Spanish - Tamaño Real ). Responding to children's interest in things that are really, really big and things that are really, really small as well as their excitement about animals, Jenkins presents gorgeous illustrations of animals and their parts, along with measurements. Kids can really see that a dwarf goby fish (1/3 inch) is, well, dwarfed by the Atlas moth, with its 12-inch wingspan. Because the illustrations are actual size, kids can compare parts of themselves to the animal parts, getting perspective on how large and small these creatures really are. Imagine the fun to be had comparing the size of our teeth to those of a great white shark (4 inches long!) or our tongues to those of an anteater (2 feet!).
Doing so, kids learn some intriguing facts, but they also use comparison and contrast to learn about themselves and the ways our bodies are similar to and different from those of other animals. We celebrate the interesting and unique capabilities and characteristics of all kinds of living creatures. So Sid can't use his foot to scratch behind his ear like Philbert can. That's ok. Philbert can't use a tape measure to figure out how long a reticulated python is!
