🎯 Your mission
Run the experiment. Find out what really happens.
⚡ The twist
What the body does in one minute is wilder than any cartoon.
Mind = Blown
🦠 You have more bacterial cells in your body than human cells.
Make a hypothesis first
Guess: how does the body solve this problem?
What You'll Learn
Cell organelles each have specific functions. The mitochondria produce energy, the ribosome makes proteins, the endoplasmic reticulum processes molecules, and the Golgi apparatus packages them.

Steps
Read the introduction and identify the main idea of this lesson.
Build a 3D cell model using household materials (plastic bag for membrane, gelatin for cytoplasm, a grape for nucleus). Label all organelles.
Compare the before and after states.
Write your conclusion: did the results match your hypothesis? What would you change next time?
