This editable learning exercise is set up so that biology pupils read four case studies and identify points that are present in each, such as overproduction, heritable variation, struggle to survive, and differential reproduction. They also predict how each population is likely to change over time. For each case, a cute cartoon animal adds interest. Although you might not cover all of the same terms in your specific curriculum, the case studies are useful. You can alter the analysis questions to more closely fit concepts of your choice.
