Testing a Hypothesis

📋 What it is

You test a hypothesis by running an experiment whose result could support OR reject it.

🗣️ Coach says

A test only counts if it could go either way. Run the experiment, look at what actually happens, and let the result — not your hope — decide. Being wrong is useful data.

🧠 Memory hook

A fair test can DISPROVE you. If it can only agree, it’s not a test.

😂 Giggle

Why did the inference feel powerful?
Because it figured out what nobody actually told it!

😲 Whoa!

The best scientists get excited when an experiment proves them wrong — that’s where the real discoveries hide.

✅ Quick check: Your experiment gives the opposite of what you predicted. Is that a failure?

Say your answer out loud first — then reveal.

🧪 Try it! (2 minutes)

Test one "if… then…" from the last mission for real. Write your prediction first, then the actual result, then compare.
