This is pretty much an whole lesson, but you’ll need to insert your own half life calculations worksheet (I have one that I like, but i didn’t write it so can’t include it here).
The lesson centres around eating chocolate M&Ms. Or Skittles if you prefer or if anyone in the room has a peanut allergy. The idea is to have something that gives you ‘heads’ or ‘tails’ when tipped out onto the desk.
