Experiment⭐ 30 XP⚡ Spark LabMitosis and Cell Division
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
Mitosis is the process in which one cell divides to form two identical new cells. It allows living things to grow, replace worn-out cells, and repair damage, such as when new skin cells form to heal a cut.

- markers
Safety First
- Dispose of materials properly after the experiment.
- Handle glass items carefully to avoid breakage.
- Do not mix unknown chemicals together.
Steps
Review the background information on Light Optics before starting.
Create a detailed food web for a local ecosystem. Include at least 8 organisms and use arrows to show energy flow from producers to top predators.
Compare the before and after states.
Write your conclusion: did the results match your hypothesis? What would you change next time?
Check Your Understanding
Question 1
1 of 3What is the main source of energy for most food chains?
Where you see this in real life
You use this every time you flip a light switch, ride a bike, or kick a ball.
Stretch Challenge
Try this in real life this week.
Time how long a small ball rolls down something, then change the slope and try again.
For the dinner table
“Show me something at home that uses this kind of energy.”
