Description
Product Details
In this unique lab activity, students conduct a forensic pig dissection by modeling the protocols used by a pathologist for a human autopsy. Students assume the role of several professionals who assist human autopsies as they dissect and analyze the various pig organs and tissues. They record their observations of external anatomy then use a Y incision to open the body cavity for a detailed examination. Students remove all organ systems, take detailed measurements, and record observations of each organ on the provided Autopsy Report. Assessment questions for each body system connect the structure and functional relationship of the observed organs and tissues. When students complete the forensic dissection, they return the organs to the body cavity and suture the incisions.
Along with the Carolina’s Perfect Solution® pigs, a preserved adult pig heart and pig kidney are also included for comparison with the dissected specimen. A set of 7 prepared slides allows students to extend and enhance the dissection by examining some of the tissue types found within each system. This fresh, new approach to pig dissection provides a real-world connection to the popular world of forensics.
Time Requirement
Teacher prep, 45 minutes. Dissection, approximately one 3-hour block (or can be divided into multiple class periods). Kit is for a class of 32 students. Note: Carolina’s Wetting Solution (items #220120A and #220121A) is recommended if completing dissection over multiple days.
Digital Resources
Includes 1-year access to digital resources that support 3-dimensional instruction for NGSS. Digital resources may include a teacher manual and student guide, pre-lab activities and setup videos, phenomenon videos, simulations, and post-lab analysis and assessments.

Learning Objectives
- Use descriptive figures and text to properly dissect a pig following an autopsy protocol.
- Examine both external and internal characteristics of the pig, including tissues, organs, and body fluids.
- Collect measurements and weights of various organs.
- Relate macroscopic observations of the pig organs to prepared microscope slide sections of lung, artery, vein, stomach, liver, kidney, and reproductive tissues.
Prerequisite Knowledge and Skills
Students should have experience using dissecting instruments. They should also be familiar with mammalian organs and organ systems.
