Selective Breeding (Part 3).
🎯 Your mission
Run the sim. Spot the pattern.
⚡ The twist
Living things break the rules of non-living things — find the rule they break.
Mind = Blown
🌳 Trees can talk to each other through underground fungus networks.
Make a hypothesis first
Predict: what will happen to the plant if you change the water?

Key Words
- natural selection
- adaptation
- fossil record
Steps

Create a Punnett square to predict the offspring of two parents. Use a trait like eye color or seed shape. Calculate the probability of each outcome.
Note any unexpected results and think about why they happened.
Share your findings with the class or a partner and discuss what you learned.
