In this one-time course, students will learn to dissect a crayfish specimen following along step-by-step with the teacher.

Class experience

Students will be able to name standard dissection tools.
Students will be able perfect dissection techniques.
Students will be able to observe the internal and external anatomy of a preserved crayfish specimen.
I was a middle school science teach for 10 years and in that time, have lead hundreds of students through many dissections including the hot dog, earthworms, clams, crayfish, and sharks. In my college Zoology class, I was the only student to successfully extract the entire spinal nerve of a crayfish that the professor had ever had! I find dissections fascinating and a good stepping stone for any student interested in anatomy, physiology, zoology, or college sciences.

Students will need a dissection kit and a preserved crayfish 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 crayfish specimen which is $2.10 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.)
In addition to the Outschool classroom, this class uses:
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 crayfish and will be part of the organ system that students dissect. Though no in-depth discussion of crayfish reproduction will occur, these organs are named and their uses are defined during dissection.

I will be on vacation from April 5-20th. I will still be answering messages but may be slower in doing so than usual as some of the time I am gone, I will not have access to wifi/cell phone data.
