|Topic||Laboratory and Hands-on Activities - Dissections|
Participants will learn dissection techniques and the anatomies of frogs, crayfish, fetal pigs or sharks. They will also learn anatomical vocabulary and scientific terms. Dissection-style classes are also offered for cows’ eyes and owl pellets.
|Grade Level||6 - 12|
|Recommended Setting||Laboratory or appropriately stocked classroom|
|Location||Governor Mike Huckabee Delta Rivers Nature Center, Pine Bluff|
Education Program Coordinator, 870-534-0011
|Suggested Number of Participants||Up to 30|
- Study the anatomy of selected species and learn dissection techniques.
- Study the physiology of the species.
- Understand the relationships of the organs.
Selected species (frog, dogfish, pig)
Virtual dissection CD and video equipment
Dissection allows a first-hand view of a species’ organs and muscles and how they are connected and interact and their position in the body.
- Prior to the class, specimens should be selected and shipped to the nature center. There will be one or two participants per specimen.
- Provide each participant (or group) with a dissection tray and utensils.
- Instruct them on the proper technique to dissect their specimen.
- Show an introductory video about the proper location of incisions and the order organs will be dissected.
- Each group will follow along so each step can be discussed.
- Answer any questions.
- What was different about each specimen?
- What were some interesting stomach contents? What does that tell about the specimen?
- What is the relationship of organs to one another?
- What were some physical traits that help the animal survive in its habitat?
Anterior – in anatomy, located near or toward the head in lower animals; located on or near the front of the body in higher animals; or located on or near the front of an organ or on the ventral surface of the body in humans
Dorsal – in anatomy, situated on or toward the upper side of the body; equivalent to the back in humans or toward the posterior plane in humans or toward the upper plane in quadrupeds
Posterior – in anatomy, (in quadrupeds) pertaining to the rear of the body; or (in humans and other primates) pertaining to the back plane of the body, equivalent to the dorsal surface of quadrupeds
Ventral – in anatomy, situated on the lower, abdominal plane of the body, equivalent to the front, or anterior, in a human
