Students will need a dissection kit and a preserved earthworm specimen. I have included the link to Home Science Tools which has a cheap standard kit for $5.60 (at the time of this writing). Amazon also has a couple for approximately $10. I personally recommend Home Science Tools. Not only is that where I purchase all of my dissection specimens but I have found them to be the most cost effective for these items. 
I have also included the link to Home Science Tools earthworm specimen which is $1.30 at the time of this writing.
Students may prefer to have disposable gloves on when dissecting. They also need a clean area to dissect (on a plate, cutting board, paper towels.)

Home Science Tools

Dissection tools are sharp and as such, your student must be mature enough to handle them on their own by your estimation. Reproductive organs are also a part of a preserved earthworm and will be part of the organ system that students dissect. No discussion of reproduction is given during class but organs are named.
