Be a flood judge
Floods can have different causes but essentially depend on three different factors: how wet the ground is, rainfall and river height. It is a combination of these conditions that determine the chance of a flood occurring.
People will press a button to that randomly mixes pictures representing the different conditions that can lead to a flood. Pushing the button again makes a selection and they’ll have to guess if a flood resulted or not. A second button reveals whether or not the guess is right.
Key learning here is around probability and that floods occur when the right conditions align. If you have one or two out of the three, there won’t be a flood. Also there are different sets of conditions that can lead to flooding, not just the ones we might think of.
