Make observations during different seasons to relate the amount of daylight to the time of year.
In this unit, students discuss how all matter in the universe is made up of different combinations of atoms formed from chemical reactions. They use scale models to compare properties of the sun, moon, and Earth, and then use that knowledge to analyze the science phenomena of how patterns are formed by the relative positions and movements of the sun, moon, and Earth. This page highlights key components of this lesson on patterns.
