Coral Reef Communities (Part 2).

🎯 Your mission

Predict it first. Then prove yourself right (or wrong).

⚡ 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

What You'll Learn

Seeds contain a tiny plant embryo and a food supply. When conditions are right—enough water, warmth, and oxygen—the seed germinates and a new plant begins to grow.
