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
Tectonic plates are huge slabs of Earth's crust that float on the mantle. Where plates meet, earthquakes, volcanoes, and mountain building occur.
Key Words
- erosion
- sediment
Materials Needed
- sand
- clay
- water
Safety First
- Use materials only as directed in the experiment.
- Keep small objects away from young children.
- Work in a well-ventilated area when using vinegar or other strong-smelling substances.
Steps
Study the diagram and label the parts you recognize.
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.
Use your senses (except taste) to describe what you notice.
Write a summary of your findings in 3-5 sentences.
