Do you lack the time and equipment for elaborate practical experiments in biology class? Why not try model experiments instead! With minimal effort, you can illustrate the processes of biology and also teach your students the modeling skills required by educational standards. Based on a biological phenomenon and tasks from different levels of difficulty, the teaching materials guide learners to the respective model experiment, which they will then conduct—partially in various social forms. The teacher's section provides you with prerequisites for learning, expected outcomes, an analogy between the experiment and reality, as well as a final critique of the model.
