Earth Systems.
🎯 Your mission
Run the experiment. Find out what really happens.
⚡ The twist
Weather isn't random — it's just complicated.
Mind = Blown
🌊 The deepest part of the ocean is deeper than Mount Everest is tall.
Make a hypothesis first
Before you observe: what shape will it leave?
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
- natural resource
- conservation
- tectonic plates
Materials Needed
- water
- plastic tray
- magnifying glass
- newspaper
- spray bottle
Safety First
- 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 Systems 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?
