Astronomy is the study of stars, planets, moons, and other celestial bodies in the universe. The vast size and distance between celestial bodies is not easy to understand especially if kids have not mastered basic distance measurements. Many kids understand distance in terms of how long it takes to get to the store or other places they frequently travel to. Thus, I am providing ideas for a Sun-Earth-Moon model that represents only the relative position of these celestial models. But, it is important for children to know that the Earth, the Moon, and the Sun are just the right size and just distance from each other to provide the perfect environment for people, animals, and plants to live on Earth.
Note: The Moon Model illustrations refers to the small circles as A and B.
5. Set the Moon Model to the side while using the following directions to prepare an Earth and a Sun model.
Note that neither the size of the Sun, Earth, and Moon models nor their distance from each other is to scale. Instead, the model only represents the position of the celestial bodies in relation to each other at one moment in time. I say this to remind you that the Moon is always rotating about its axis as it orbits the Earth. Like the Moon, Earth rotates about its axis and with its Moon, together, they orbits the Sun.
2. Tape the free ends of each of the three models to the clothes hanger as shown.
3. Adjust the length of the strings so that the Earth is in line with the Sun and the Moon is slightly higher than the Earth.
5. Add stick-on stars to the hanger.
