Who Started It All? The Spread Of Disease
Students predict the spread of disease to be exponential. They then do a hands on "sharing of bodily fluids" and see the actual data and compare these results to the projected model. You actually see the number of infected after each sharing to see the shift of the model easier. Written to be c...https://education.ti.com/en/activity/detail/who-started-it-all--the-spread-of-disease
