Light Optics.
🎯 Your mission
Run the experiment. Find out what really happens.
⚡ The twist
Speed isn't the same as force. Don't mix them up.
Mind = Blown
⚡ Static electricity is the same physics as lightning, just smaller.
Make a hypothesis first
Guess: where does the energy go?
What You'll Learn
All living things share basic characteristics: they grow, reproduce, respond to their environment, and need energy to survive. Plants make their own food through photosynthesis, while animals must eat other organisms.

Steps
Read about Light Optics and write down three key facts.
Design a controlled experiment: grow plants under different light conditions (full sun, partial shade, no light). Water equally and measure growth daily for one week.
Compare the before and after states.
Write your conclusion: did the results match your hypothesis? What would you change next time?
