As Emily clarified many of the moon concepts, questions began arising about the orbit of the earth.
Emily: “We think the moon as moving around the earth, but why is it moving around the earth?”
*Emily swings the ball and string in a circle above her head* “Why is the moon moving around the earth?”
Student: “because you're swinging it.”
Emily: “Whats making it go around? Why isn't it just flying off?”
Student: “The string!”
With the ball and string visual representation, the students were able to see how the earth has a gravitational pull on the moon. | |
