Intermediate 等級
Frogs are an intermediate dissection specimen....as such, you must have taken Beginning Dissection with me, a Beginner dissection specimen class (Earthworm, Starfish, Clam), or have previous dissection experience. As the only amphibian in our dissection classes, the frog does share some semblance with our other intermediate specimens.....more complete organ systems. We will be able to see a more complete heart than we have before (multiple chambers) as well as a more developed nervous system (brain, spinal cord, nerves). 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 frog before beginning the dissection. As the dissection begins, students can expect to observe the spinal cord, stomach, intestines, bladder, liver, and kidneys. We will continue to discuss the terms dorsal, ventral, anterior, and posterior in terms of each specimen. 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 frog 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 to perfect dissection techniques.
Students will be able to observe the internal and external anatomy of a preserved frog 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 frog and will be part of the organ system that students dissect. Students will be able to determine the sex of their specimen. Frogs have a more developed reproductive system than others we have dissected before and students will be exposed to the following terms and organs: testes, sperm ducts, ovaries, uteri, eggs.
供應清單
Students will need a dissection kit and a preserved frog 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 frog specimen which is $4.40 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 have taught on Outschool for 4 years. In that time, I 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.
