Guess, Test, Learn — The Hypothesis Game

What You'll Learn

🧠 A hypothesis is a smart guess that you can TEST. Scientists don't just guess randomly — they make educated predictions, then run experiments to see if they're right. Here's how to do it: 1. Look carefully at the problem. What do you see? 2. Think about what you already know. Does this remind you of something? 3. Try an answer! It's totally okay to be wrong — that's how we learn. 4. Check: did it work? If not, try something else! You're building your thinking muscles. The more you practice, the stronger they get!
