Dissections (GMHDRNC) |
| Topic | Laboratory and Hands-on Activities - Dissections |
| Summary | 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.

- Study the anatomy of selected species and learn dissection techniques.
- Study the physiology of the species.
- Understand the relationships of the organs.

| Background | 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.
|
| Procedure |
- 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.

| Review |
- 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?
