Use this comprehensive lab on the earthworm dissection to enhance your life science classroom. There are pre-lab questions, an introduction, detailed lab procedures with diagrams and explanations, and most importantly a teacher answer key at the end. I've also included a great website to purchase specimens for dissection. This lab guide should make the earthworm dissection much more navigable.
