Plate Tectonics.
🎯 Your mission
Set it up. Test it. Be amazed.
⚡ The twist
Nature loves to surprise the careful watcher.
Mind = Blown
🔬 The more you look, the more nature shows you.
Make a hypothesis first
Before you start: write down what you think will happen, and why.

Steps
Review the background information on Plate Tectonics before starting.
Model erosion: tilt a tray of soil and pour water from a cup at the top. Observe how channels form. Try adding plants or rocks to slow the erosion.
Watch carefully for any changes and note the time.
Create a data table to organize your measurements.
