Jiminy cricket! If you find yourself plagued by fear of dissection, these locust respiratory system dissection directions will walk you through everything you need to know. Teens inspect a living locust to begin with, then jump over to the dissection of the insect (the materials call for a living locust and a cadaver locust for each group, so they do not euthanize their living insect). Although the worksheet is written in British English (ventilation system = respiratory system), it is a Word document, so you can edit as needed, or point out the differences to bring a little geography or linguistics into your science classroom.
