Two students used two balls to make a scale model of the Earth/Moon system. The Earth model was 10 cm in diameter. How far apart should the students place the Moon and Earth models?
Answer:Procedures. Ask students to guess how far away the Moon is from Earth. When the answer (or a close approximation) is given, or several guesses have been made, share the distance with students (384,400 kilometers or 238,855 miles).
