Light Optics.
🎯 Your mission
Set it up. Test it. Be amazed.
⚡ The twist
Energy never disappears — it just hides somewhere else.
Mind = Blown
🎢 You feel weightless on a roller coaster because you and the seat are falling at the same speed.
Make a hypothesis first
Before you start: which will move faster, and why?

Steps
Read about Light Optics and write down three key facts.
Model natural selection: scatter colored paper scraps on grass. Time how long it takes a partner to pick up each color. Which color survived longest? Why?
Watch carefully for any changes and note the time.
Create a data table to organize your measurements.
