Human Organ Systems
Unit
Chad Martin
Lodge Grass Jr. High
Science Horizons Initiative
A 7th Grade Life Science
Proposal
• Understandings: Students will compare the
structure and function of cells, tissues, organs
and organ systems in the human.
• Essential Question: What are the structure,
function and relationship among cells, tissues,
organs and organ systems in the human?
Montana K-12
Science Content Standards
End of Grade 8, Content Standard 3.1
states that students will study the relationship
among cell, tissue, organ and organ systems in
the human.
Ace Curriculum Standards
Ace Curriculum Standards LS 11.0, and
13.0 state that students will create a testable
question and hypothesis. They will analyze data
with a graph.
Bloom’s Taxonomy
Following Bloom’s Taxonomy, students
will evaluate data which includes norms,
controls and multiple assessments.
Students Will Know
 In Section 1 students will describe how tissues, organs and
organ systems are related. They will list 11 organ systems. They
will identify how organ systems work together to maintain
homeostasis.
 In Section 2 students will identify the major organs of the
skeletal system. They will describe four functions of bones.
They will describe three joints.
 In section 3 students will list three kinds of muscle tissue.
They will describe how skeletal muscles move bones. They will
compare aerobic exercise to resistance exercise. They will
describe two muscular system injuries.
 In section 4 students will list four functions of skin. They will
describe the two layers of skin. They will describe the function
of hair and nails. They will describe two kinds of damage that
can affect the skin.
Holding Ice Start-Up Activity
Performance tasks: The students will do a StartUp Activity comparing a hand with no ice to a hand
with ice using thermometers and an infared
thermometer. They will write a testable question and
hypothesis. They will record, graph and evaluate
temperature data. They will write answers to higher
level thinking questions.
Text Assessment
• The students will read and answer the question in the
four sections in the book about organ systems, the
skeletal system, the muscular system and the
integumentary system. After completing the four
sections the students will answer the Chapter Review
questions. They will then take the Chapter Test.
Creating a Brochure
The students will choose an organ system
and create a brochure (both sides of photocopy
paper folded into thirds) about it. After
examining examples of brochures they will use a
variety of books, internet and other sources to
draw, describe and discuss cells, tissues, organs
and organ systems. They will be graded on the
rubric of labeling, explaining, creativity and art.
The brochures will be displayed in the hall
display case for everyone to see.
Athletic Physical Form
The
students will
check and discuss
how many times
each organ
system was
evaluated in the
athletic physical.
The Circulatory System and Exercise
Start-Up Activity
The students will do a Start-Up Activity about
exercising the heart. Students will learn to use a
stethoscope to monitor their heart, take their pulse with
their fingers and take their systolic and diastolic blood
pressure. They will use the Vernier-Texas Instruments
CBL (computer based lab) System to graph their heart
beats. They will Take their resting pulse and blood
pressure. They will do jumping jacks for 1 minute. They
will then check their pulse and blood pressure. After
resting for 5 minutes they will check their pulse and blood
pressure again. They will answer the Analysis questions.
Human Organ System
Science Fair Projects
The students will choose 1 of 5 possible science fair
projects: 1. Off All the Nerve about which parts of the body
are more sensitive to touch, 2. No Nose No Taste about how
smell influences taste, 3. Fingerprint Findings checking
similarity of fingerprints in a family, 4. Are Dogs Colorblind?
5. Build Your Own Lungs.

check the life science on the bottom and health and fitness in
the blank on the right opens up about 500 science fair
experiments.
The students will do the experiment, write the results
and answer the research questions. Students that make a large
display about their experiment will get extra credit.

The Impact On Understanding
Science
This unit is an inquiry based opportunity for seventh
grade students to learn about how their bodies function.
The students are interested in this subject and will
enthusiastically study any information presented to them as
well as apply what they learn from the labs to their lives.
The students will develop higher level thinking,
communication, goal setting and the planning process in
science. They will apply science knowledge and skills to
solving problems, conducting research, using scientific
equipment properly, applying knowledge
of the relationship between humans and the
environment and develop technical skills.
