Weathering and Erosion.
🎯 Your mission
Set it up. Test it. Be amazed.
⚡ The twist
The slowest changes are the biggest ones.
Mind = Blown
🪨 Every grain of sand on every beach used to be a mountain.
Make a hypothesis first
Predict: which will erode faster?
What You'll Learn
The water cycle describes how water moves through Earth's systems. Water evaporates from oceans, condenses into clouds, falls as precipitation, and flows back to the ocean.
Key Words
- rock cycle
- weather
- water cycle
Materials Needed
- rain gauge
- cotton balls
- food coloring
- clear container
Safety First
- Dispose of materials properly after the experiment.
Steps
Review the background information on Weathering and Erosion before starting.
Create a model of the water cycle in a bowl: place warm water in a bowl, cover with plastic wrap, put ice on top, and observe condensation and precipitation.
Compare the before and after states.
Write your conclusion: did the results match your hypothesis? What would you change next time?
