Design and test a paper helicopter. What is the best design?
Do you know which birds are regular visitors where you live?
Why do epidemics take off? Why don't they just carry on for ever once they've started? These simple models will help us to understand what's going on, and how science can help us to prevent epidemics happening in the first place.
Equipment required: people - lots of them!
Questions to consider:
Equipment required: people, each with a slip of paper and a pen/pencil, plus optional counters and string
Equipment required: one die and about 20-30 counters per small group (any colour)
There are other simple models which help us to explain features of epidemics, and you can find some on our sister website, Motivate.
You may also like to try creating your own model. What features would you like your model to have? Have could you incorporate them in a simple model?
