Earth's History.
🎯 Your mission
Predict it first. Then prove yourself right (or wrong).
⚡ The twist
The slowest changes are the biggest ones.
Mind = Blown
🌊 The deepest part of the ocean is deeper than Mount Everest is tall.
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
Materials Needed
- rain gauge
- cotton balls
- food coloring
Safety First
- Keep small objects away from young children.
- Work in a well-ventilated area when using vinegar or other strong-smelling substances.
- Dispose of materials properly after the experiment.
Steps
Review the background information on Earth's History 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?
