Dear Model Makers,

Yesterday you made models that showed what causes the Earth’s seasons. I love models because they simply but clearly show a process. When you make models, you have to show the really important parts and how they interact.

What you make your model out of doesn’t really matter. For us, Earth was dum-dums and the Sun was a yellow dot. What matters is that you show how the parts are related.

Sincerely,

Mr. Heimbuck
