Lesson 9 - Modeling Earths Rotation (and Revolution)

1. Why is it important to use models while explaining and teaching?
2. What are some limitations of models? 
3. How did you decide on the model to use for this video?

1. I feel that it is important to use models because it helps show and explain what you are trying to teach. It provides a visual.
2. It might not look the right way and you might get the wrong visual. It might be to distracting and you wouldn't learn from the video or you could zone out.
3. I decided to use a sphere shaped object because it looked like the earth which is round like a sphere and I used a marker to mark where the equator is on the earth.
