Hypothesis: What effect does the height of the meteoroid have on the craters that form?
If it is tall it will make a deep hole because it has lots of weight on the height (even if it was light)

- Which of the following best describes Earth’s shape?
A. disk
B. circle
C. sphere
D. plane - Earth’s gravity pulls an object toward its ____________________.
- Which model do you find most useful to explain gravity and its effects? Why?
- Tennis ball and rubber band?
- Styrofoam ball and toothpicks?
- Circle on paper with arrows? - Why are models helpful at explaining complex scientific concepts like gravity?
- Do you think the moon is affected by Earth’s gravity? If so, why doesn’t it fall “down” toward the Earth?
- Why doesn’t a plane or bird fall from the sky?
- Does gravity ever stop working? Do any forces ever cancel out gravity or reverse it? Explain.
- Why is this lesson on gravity a good time to teach about craters?
- Sphere because scientificity scientists proved that the Earth was a sphere. Even though it is not a perfect sphere, Earth is one. To prove this, if it wasn't you would fall off the edge and nobody has done that.
- Core/Center because the center of Earth is called the core.
- Tennis ball and rubber band because it explains the power of gravity and some people underestimate the power of it. Also, you could also try to escape gravity and you can't.
- Well, some people can't understand it without models. Plus, models are more fun and also they give you a way better visual than words.
- Yes because if it wasn't, the moon wouldn't be in the Earth's orbit. Also, it doesn't fall down because the sun is also pulling and also Earth's gravoity wouldn't be able to pull the moon all the way down.
- A bird doen't fall because it is contantly flapping its wings. Also, if a bird would fall down whats the point of wings?
- No because there is no way to stop it. No forces ever channel out gravity but they can have less gravity.
- It's good because gravity is the cause of craters. For an example, the moon has lots of craters because of objects hitting it (meteorite). This happens when a plaent hits an object in space or an object hit the planet.
