I modified this CER from the NSTA case research referred to as “Capturing the Poop.” The case focuses on the commentary that caterpillar will fling their feces away from the nest. You play play this quick youtube clip to see the frass flinging enjoyable. Is that this an adaptive habits? Do the caterpillars acquire some profit from preserving their shelters tidy?
College students first study a graph that exhibits the age and mass of caterpillars from two teams: a clear group and a frassy group. Then, they make a CLAIM based mostly on the information proven. In addition they establish the unbiased and dependent variables. Lastly, college students summarize the proof that helps the declare being made within the graph. Total, the graph exhibits the the tidy nests have bigger larvae that pupate sooner.
Within the second set of information, college students decide if frass flinging has an impact on predation. In addition they establish the declare, variables, and create a abstract of the proof. On this remaining part, college students should develop a reasoning assertion that ideally will mix each units of information to reply the unique query.
I take advantage of this exercise with a brief unit on animal type and performance. You possibly can even order caterpillar package for college students to view precise caterpillars s they rework into butterflies. Different actions on this unit embody an animal habits lab and a rat dissection. Usually, that is the final unit earlier than vacation break in December, so I have a tendency to combine and match what I do relying on the time I’ve left.
