Descrição

In this article we propose a hands-on experimental activity about predator–prey interactions that can be performed both in a research laboratory and in the classroom. The activity, which engages students in a real scientific experiment, can be explored not only to improve students’ understanding about the diversity of anti-predator behaviours but also to promote their understanding about the various stages of experimental scientific procedures, such as the definition of a research problem, the statement of testable hypotheses, designing the experiments and drawing conclusions based on the evidence.
