Students learn to take their own data, record it, analyze it, and create a scientific hypothesis from it. These hypotheses will enable the students to make a prediction.
Students also learn to work with the metric system.
To learn the effects impact cratering has had and will have on the Earth and the planets. Since the formation of the solar system, meteorites have been forming impact craters on the surface of all the solid planets and their moons. This process has been important in the evolution of the planets. Cratering caused early melting on the planets and excavated fresh sub-surface material. One motivation for these lessons is to learn about mass extinction, one effect impacts have had on life on Earth.
