Muscular System – The Big Ideas
•
•
•
The muscular system allows the body to move.
Major types of muscles include voluntary and
involuntary muscles.
Muscles types are different throughout the
body.
Muscular System – Prior Knowledge
Students will have knowledge of some systems
of the body prior to this study. It will be helpful
for students to use the Fun-damental, Building A
Body, to review the Muscular System. It will also
help if they are able to:
• Explain that the body is made up of systems.
• Understand the role of the skeleton in supporting
the body.
Muscular System – Common Misconceptions
• Muscles are not found all over the body.
Reality: There are three types of muscle: smooth, cardiac, and skeletal
which account for over 600 muscles found throughout the entire body.
• If you stop exercising, your muscle will turn into fat.
Reality: Muscle is made up of individual cells that undergo all
kinds of complex metabolic processes. Fat cells are simply
storage packets of lipids. One type of cell can not change
into another type of cell.
Muscular System – Using DE Science Content

Muscular System – Instructional Ideas
• Read the reading passage, Skeletal Muscles–
Move That Body!
– Lead students in a game of Simon Says. As you play,
point out muscles as they are used. (i.e. muscles in
the face while smiling or frowning, the many muscles
in the tongue while moving it, the leg muscles as you
flex your foot, etc.)
Muscular System – Instructional Ideas
• Watch the Video Segment, Involuntary Muscular System.
– Teach students how to take their pulse. Explain that the pulse
measures the number of times a person’s heart beats per
minute.
– Record student pulse rates on a large piece of chart paper.
– Instruct students to march in place for 60 seconds and take their
pulse again.
– Record student pulse rates in a second column on the chart.
Compare the two pulse rates to show how the heart muscle
works by beating faster when we move.
