Ecosystems.
๐ฏ Your mission
Predict it first. Then prove yourself right (or wrong).
โก The twist
Living things break the rules of non-living things โ find the rule they break.
Mind = Blown
๐ณ 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?
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.

Compare the before and after states.
Write your conclusion: did the results match your hypothesis? What would you change next time?
