🔬 How to Use the Greenhouse Effect Simulator
What is This Simulator?
The Greenhouse Effect Simulator is an interactive tool created by PhET (Physics Education Technology) at the University of Colorado. It shows you how greenhouse gases work in real-time! You can add CO₂, remove clouds, and watch how it affects Earth's temperature. This is REAL science! 🌍
🎮 Controls & How to Play
1. Adjust the Thermometer:
Use the controls to change CO₂ levels. More CO₂ = hotter Earth! Try moving the slider all the way up to 1000.

2. Add/Remove Clouds:
Click the cloud buttons to add more clouds. Clouds trap even MORE heat! Watch the temperature rise.

3. Watch the Thermometer:
See how Earth's temperature changes as you adjust the settings. The arrow points higher = hotter planet!

4. Compare Scenarios:
Try different combinations. What heats Earth more - CO₂ or clouds? Experiment and find out!

💡 Learning Tips
- Start at 280 ppm: This is Earth's CO₂ before humans changed it. Notice it's cooler.
- Go to 400 ppm: This is TODAY's CO₂ level. See how much hotter it is?
- Push to 1000 ppm: This is what could happen if we don't act. The temperature gets scary hot!
- Notice the pattern: More gas = more heat. This proves the greenhouse effect is REAL.
❓ Common Questions
Q: Why does CO₂ trap heat?
A: CO₂ molecules let sunlight through but trap the heat that bounces back from Earth. It's like a blanket!

Q: What if I make the planet really hot?
A: Great question! That's what will happen if we keep adding CO₂. That's why we need to ACT NOW! 🌱

Q: Can I undo my changes?
A: Yes! Just move the sliders back. You're in control of the planet's temperature!

Q: How long should I play?
A: Play for as long as you want! Try different combinations and see what you discover. Science is fun!

🚀 Challenge Ideas
- Try to keep Earth at a temperature where life is comfortable. What CO₂ level works?
- Compare 1800s Earth (280 ppm) with today (420 ppm). How much did it warm?
- Test: Which heats Earth more - doubling CO₂ or doubling clouds?
- Predict: If we keep adding CO₂ at this rate, what will Earth look like in 50 years?
