Objectives

The student will:
• Label the following internal organs of a wolf on the diagram with 80% accuracy: heart, lungs, kidney, liver, gall bladder, spleen, stomach, intestines, bladder, spine, shoulder, pelvis, skull, and
brain.
• Layer/assemble the wolf’s organ bag, skeleton, and skin with 100% accuracy.
• Identify, in writing, the differences between the organs a wolf, a human, a frog, and an elk.
• Hypothesize, in writing, why there are differences and/or similarities between organs of different
species.
• Analyze hypotheses using facts about the functions of the organs listed in the first objective.

Background
An organ is made up of tissues, and it is a part of the body that performs a specialized physiological function. An organ system is a group of specialized organs that work together to achieve a major physiological need. Take for example, the stomach. The stomach contains epithelial tissue, muscle tissue, nerve tissue, and connective tissue, and as an organ it has a specific function—breaking down food. The stomach is part of the digestive system. The digestive system is responsible for breaking down foods into nutrients that can be transported through the bloodstream. The muscular/skeletal system of an animal refers to the systems that give the animal its shape, protects its organs, and allows it to move. The reproductive system of an animal is how that animal makes more of itself or has babies. The excretion system of an animal is responsible for getting rid of the animal’s wastes and allowing the animal to use energy to do its work. All these systems influence where an animal lives and how it survives. Depending on how advanced these systems are in animals determines which group they belong in, as well as how alike the systems are between and among the animals.

Procedure

The instructor will:
1. Copy and distribute a set of wolf worksheets to each student.

2. Instruct students to cut out the body shape, organs, and skeletal structure of their wolves.

3. Instruct students to layer the parts of their wolves in the correct order.

4. Have students color the organs listed in the first objective.

5. Have students label the organs on their wolves.

6. Have students compare and contrast the organs of wolves with similar organs in humans, frogs, and
elk.

7. Have students hypothesize why there are differences and/or similarities.
