Heads, tails… or maybe?

The Maybe-Coin Lab

Make a prediction, flip a coin 100 times and discover how probability, randomness and the idea of superposition work.

Before you begin

You’ll guess what might happen, make a choice, test it, and explain what changed. Wrong guesses are allowed (and encouraged).

How to use

  1. Read the challenge.
  2. Build or choose a model.
  3. Test it.
  4. Improve it.
  5. Explain why your final choice works.

Learning goals

  • Make a prediction and test it with an experiment.
  • See patterns appear in lots of random results.
  • Explain what a “maybe state” means before you look.

Think again

What surprised you? What are you still not sure about? What would you test next?

About this prototype

Version 1, a working prototype. It hasn’t been tested with classes yet, so I’m not claiming any learning results.
