레벨 Intermediate
Crayfish are an intermediate dissection specimen. Also known as 'crawdads', these animals are widely distributed around the world in lakes, streams, rivers, and creeks. Crayfish have an exoskeleton and a variety of well-developed organ systems. Unlike some of the beginning dissection specimens, in a crayfish, we will begin to see organs as we know them....fully functioning brains and hearts. 

At the beginning of class, we will review the dissection kit tools and their uses. We will also observe the external anatomy of the preserved crayfish before beginning the dissection. As the dissection begins, students can expect to observe the crayfish cephalothorax, stomach, gills, heart, intestines, nerve cord, green glands (rudimentary kidneys), and appendages.

Students need to have either taken Beginning Dissection or have previously used a dissection kit in order to take this class. If they have not, please take my Beginning Dissection class prior to this one. Dissection tools are sharp! Your student must be able to maturely handle these tools during class. 

Recommended Order of Dissection Classes: 
Beginning Dissection
Beginner Earthworm Dissection
Beginner Starfish Dissection
Beginner Clam Dissection
Intermediate Crafish Dissection
Intermediate Perch Dissection
Intermediate Frog Dissection
Advanced Pig Dissection

Students also need to have their own dissection kit, preserved crayfish specimen, and a clean place to perform the dissection. Some students also prefer to wear gloves while dissecting as well. 

Please note, fewer numbers of students may result in a shortened class time. 

There will be no refunds issued for a student(s) missing class.

학부모 가이드
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.
수업 자료
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.)

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.
