Latex gloves are preferred, but not entirely necessary. How many toes are present? To what structure does the Eustachian tube attach?
Play with the tongue. You may also remove the eyeball. When students ask me questions, I require them to at least have a book open to the appropriate page to show me they tried to find the answer on their own. I usually grade the questions and labelings from the Frog Dissection Handout and also give them a paricipation grade based on how well they did the lab, such as cutting the frog, cleaning up, and working well with others.
It is not necessary for this lab to get the injected frogs. Students should wash hands even if they wore gloves. None of the answers are that difficult, and most biology teachers or science teachers should have little difficulty answering the questions on the guide.
The bullfrogs are messier and hard to cut, I have a "lottery" to pick a group to do the bullfrog and then the other students in the class can see what it looks like. Group sizes - I usually put my students in groups of 2, possibly three if I have an odd number of students.
You can purchase akey from Teachers Pay Teachersfor 1. I typically end up removing a student from the class the first day, this student must do the alternate assignment in the hall.
I have resources such as lab manuals and frog dissection guides laying around the lab. Does it attach to the front or the back of the mouth? I usually order mine from carolina. This is just simply a way for me to limit access to students, and it helps with hosting costs. Examine the hind legs.In this lab you will: dissect an adult frog and observe the external and internal anatomy of a frog, compare the internal anatomy of a frog to that of a human, and make inferences of the functions of structures that make the frog adapted to its environment%(2).

Description: After reviewing lab safety and introducing the dissection procedure, students dissect a preserved frog in order to observe the external and internal structures of frog anatomy. Lab Resources - The frog dissection gallery is a good resource for teachers and students to review the parts of the frog.
I also encourage my students to try to discover the answers to their questions before asking for help.
Start studying frog dissection pre- lab: External anatomy. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
Today, we're going to go over some of the important anatomical structures you would find both externally and internally during a frog dissection.
External Frog Anatomy. Before starting any dissection, it's important to look around at the external anatomy, or anatomy visible outside the body.Download
