Abstract
Guided-inquiry lab activities with bean beetles (Callosobruchus maculatus) teach students how to develop hypotheses, design experiments, identify experimental variables, collect and interpret data, and formulate conclusions. These activities provide students with real hands-on experiences and skills that reinforce their understanding of the scientific method and experimental design. This teaching method can easily be adapted to other test organisms or alternative themes.
