The most common frog dissection method is to slice a capital "I" shape on the ventral side of the frog. Peel open and pin back the skin, then repeat this for the muscle layer. Remove fat bodies and observe.

In a typical frog dissection class, you will discuss the anatomy and physiology of frogs and other creatures. You will learn about the skeleton, muscles, and internal organs of the amphibian.
Dissecting the nerves last in a frog allows you to examine the muscles and organs first, which can give you a better understanding of how the nervous system interacts with the rest of the body. It also ensures that the nerves are not accidentally damaged during the initial dissection process.
You can typically find the answers to a frog dissection worksheet in your biology textbook, online resources, or by asking your teacher for assistance. If you are having trouble locating the answers, reaching out for help from a classmate or tutor can also be beneficial.
It is estimated that tens of millions of animals are used for dissection in educational settings each year. The most commonly used animals include frogs, rats, mice, and pigs. Many organizations advocate for the use of alternative teaching methods to reduce the number of animals killed for dissection.

The frog dissection is described on pages 148-151 in the book "Speak" by Laurie Halse Anderson.
It is not necessary, but this can help hold the frog in place more efficiently.
I wouldn't advise using a live frog for dissection as that is cruel. Most schools and universities use fogs that have been purchased and are already dead, stored in a preservation solution.
This is essentially targeted euthanasia. While the frog is anesthetized, splitting the connection between the brain and spine kills the frog without damaging most of the body.
i don't know u figure it out and stop cheating on your frog dissection worksheet!:[
Because dead body tissue for dissection is preserved with formaldehyde, which when generously portioned onto the skin can cause severe cases of cancer.
After the dissection, clean up by disposing of all biological materials properly as per safety guidelines. Wipe down the dissection tools with a disinfectant solution and wash your hands thoroughly. Clean the dissection area with a disinfectant to ensure proper sanitation.
That would most definitely be the intestines. (I actually just did a dissection today, and had to measure everything.)
