Professor O will help you learn: Dropping balls into a tray of flour shows how meteorites smashing into the Moon made its craters, and lets you test how the size and drop height of a space rock changes the crater it leaves.
⚠️ This is a messy, floury activity, so lay newspaper down and do it somewhere easy to sweep up.
Play through the project step by step, with narration read aloud.

Make it your own: Change one thing at a time — a bigger marble, a higher drop, or a heavier ball — and measure how wide each crater turns out.
