SolarSystem

One of the first Great Lessons is the story of the universe, including the formation of the Earth.

For a long time, humans have used the positions of the Sun, the moon, and the stars to help them tell time, figure out where they were while sailing at night, and even calculate how large the Earth is. Besides observing the movement of celestial bodies and making inferences about the structure of the solar system, our first science projects will focus on these practical applications of this knowledge.
