Light Optics.
🎯 Your mission
Understand the idea. Then look for it everywhere.
⚡ 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.

Steps
Read about Light Optics and write down three key facts.
Compare the skeletal structures of a bird wing, human arm, and whale flipper using diagrams. Identify homologous bones and write what this tells us about common ancestry.
Compare the before and after states.
Write your conclusion: did the results match your hypothesis? What would you change next time?
