課堂經歷
Starfish are an amazing part of the marine ecosystem. In fact, they are the most important predator in the shallow water biome. They are known as a keystone species.....meaning their feeding has an effect on the whole ecosystem. They have a fun anatomy to dissect and because of this, they are a good beginning specimen to start with. 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 starfish before beginning the dissection. As the dissection begins, students can expect to observe a starfish's rays, digestive glands, reproductive glands, pyloric and cardiac stomach, mouth, ampullae, and tube feet. Other dissection classes available for this age 7-9 are: Beginning Dissection, Beginner Earthworm Dissection,(7-9) and Beginner Clam Dissection (7-9) 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. Students also need to have their own dissection kit, preserved starfish 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.
學習目標
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 starfish specimen.
其他詳情
父母的引導和規範
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 starfish and will be part of the organ system that students dissect. Though no in-depth discussion of reproduction will occur, reproductive glands are named.
供應清單
Students will need a dissection kit and a preserved starfish 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 starfish specimen which is $3.25 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 teacher 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. 評論
