How Long Is A Light Year?  |  How Much Do You Weigh In Space?  |  The Capacity of Planets  |  More Math Concepts

Space and Mathematics Math really is "out of this world" when it's applied to space travel and the planets! Measurements of very large and very small numbers require knowledge of scientific notation; measurements of distance, rate and time is necessary in determining aspects of space travel; and attributes of planets in our solar system involves knowledge of measurement. This month, we'll look at problems that connect space and mathematics, especially in regard to measurement.

"How Long Is A Light Year?" deals imaginary situations with light year calculations from other planets. Students demonstrate the ability to use a light year as a standard of measurement to calculate time and distance from the earth.

"How Much Do You Weigh In Space?" deals with weight as a measure of gravitational attraction. Students demonstrate the ability to apply the use of decimals, fractions, ratios, and proportions to situations based upon given information about planets in the solar system.

"The Capacity of Planets" deals with the solar system of planets and size comparisons. Students demonstrate the ability to represent numbers in scientific notation and use geometry to solve problems about planets in the solar system.
