Mammalian Organ Pack – TSP
In addition to the actual dissection of each organ, there are interactive activities and formative assessments sprinkled throughout the program, for each organ, to help review and solidify student learning. Each organ dissection is a stand-alone experience and can be performed in any order. Time estimates and the highlights for each section are provided below.
Introduction Running Time: 9 minutes
- Wendy’s welcome
Human Heart Running Time: 25 minutes
- External Features (left/right atria, left/right ventricles, interventricular sulcus, aorta, pulmonary trunk, superior/inferior vena cava)
- Internal Aspects (interventricular septum, tricuspid valve, chordae tendineae, pulmonary valve, mitral valve, trabeculae carneae, aortic valve)
Cow Eye Running Time: 25 minutes
- External Features (occipital lobe, optic nerve, sclera, cornea)

TOTAL RUNNING TIME: 120 MINUTES
The Importance Of Dissection
Dissection labs excite students and motivate them to ask probing questions about anatomical structures and processes, to identify patterns across species, and to relate structure to function. When students reach high school, dissections can be used as evidence for model building and as empirical evidence to support theories. Dissection of a small mammal is a hands-on approach for students to gather information on organs and organ systems necessary to develop a model of interacting systems that is also applicable to larger mammals, such as humans.

DISCIPLINARY CORE IDEA
LS1.A: STRUCTURE AND FUNCTION: Multicellular organisms have a hierarchical structural organization, in which any one system is made up of numerous parts and is itself a component of the next level.
HS-LS1-2: Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.
