    In this activity, students model the radioactive decay process for carbon-14 by flipping coins. Each coin represents a carbon-14 atom, and if it lands tails up when flipped, this indicates radioactive decay.

    By the end of this activity, students should be able to:

    • appreciate the randomness of radioactive decay
    • describe the concept of half-life
    • explain the exponential nature of radioactive decay
    • relate the radioactivity features of half-life, exponential decay and randomness to C-14 dating of artefacts.
