According to Taylor Smith, a student, I’m going to vomit. Rob Glotfelty’s life sciences laboratory is littered with a pile of dead frogs, vacuum- sealed, and piled five high. While some students may be squeamish about dissecting an animal, many find it to be a fascinating and enlightening experience. Many students are first exposed to dissection in middle school and it can be a great opportunity to learn about anatomy and physiology. Most middle schools in the United States offer some form of dissection, whether it is frogs, earthworms, or squid. This is a great introduction to amphibians that will teach you everything you need to know about their anatomy, physiology, and function. The percentage of North American students who dissect an animal by the time they graduate from high school is 75 to 80%.Īs one of the first laboratories, it is common for biology students to perform frog dissections. An examination of evolutionary adaptation provides an insight into how an animal evolved from an aquatic to land-based life.ĭuring the 1920s, American K-12 schools began using animal dissections in place of English. It is an established process that allows the study of vertebrate anatomy as well as the development of mature body systems from preserved frogs. They sell the specimens to schools for up to ten to twenty times the original cost and then ‘process’ and preserve them as specimens. These companies provide a wide range of animals, including cats, frogs, fetal pigs, dogfish sharks, and a wide range of other species, for as little as half the price of reputable pet stores. To examine the leg muscles, you must first pull off the skin.Īnimal specimens are purchased from biological supply companies for use in the classroom. To get a better idea of where your frog is, take a few minutes to look around. We’ll be able to look at, discuss, and demonstrate reptile items that you’ve brought with you to class. We will give you an extra credit of $3 for next week. Take advantage of these fun lessons whenever you need them, whether you are teaching a classroom, hosting a homeschool program, or participating in a co-op program. The lessons are written for a class that meets once a week. Students will study biology in this lesson as part of a 32-part series. It is also important to review safety procedures with students before beginning the lab.Ī frog dissection lesson for middle school biology students. This should include a description of what will be done during the lab and why it is important. Teachers should provide a brief introduction to the lab before starting. Frogs are a common animal used in dissection labs in middle school.
