Materials Needed

• 1 large baking tray
• Flour (enough to cover the bottom of the tray)
• Cocoa powder (for dusting the surface)
• Small rocks or balls (to create impacts)
• Measuring cup
• Ruler

Instructions

1. Begin by pouring enough flour into the large baking tray to create a uniform layer covering the bottom.
2. Use a measuring cup to ensure the flour layer is about an inch thick for best results.
3. Dust the top of the flour layer with cocoa powder to represent the surface of the moon.
4. Choose small rocks or balls of different sizes to simulate meteoroids.
5. From a height of about 1-2 feet, drop the rocks or balls onto the flour surface one at a time.
6. Observe the craters formed by each impact and measure their sizes using the ruler.
7. Discuss how different sizes of objects create different crater sizes and depths.
8. Experiment by dropping the same object from different heights to see how it affects the crater.
9. Encourage children to record their observations and findings in a notebook.
10. Wrap up by discussing what causes craters and how they can be found on the moon and other celestial bodies.
11. Ask kids to share their favorite part of the experiment and what they learned.
