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.
