I teach in an exciting school where my students are able to experience many different things. In learning about metamorphosis I was able to get them into the creek that runs behind school where they found different macro-invertebrates and were able to use guides to identify and draw the different macros.
Afterward students chose a macro to study. I found a great website that has little identification sheets for each and macro. Students were able to use these and recreated the life cycle and wrote about the cycle.
