Brainpop: Muscles
Muscle Power
• More than a few. The human body has more than 650
muscles.
• Unique in its own way. No two muscles in the body have
exactly the same function. When one muscle is paralyzed,
either stability of the body part is impaired or some specific
movement is lost.
• Watch your step. Forward locomotion such as walking or
running is actually the process of losing and catching one's
balance.
• Boost your burning power. Did you know that for every 1 lb of
muscle you gain, your body burns an extra 50 calories a day? If
you can turn at least 5 lbs of extra "fat" into muscle, you will
automatically burn an additional 250 calories per day.
Say Cheese!
• Muscles normally account for 40%
of one's body weight.
• You have over 30 facial muscles
which create looks like surprise,
happiness, sadness, and frowning.
• Eye muscles are the busiest
muscles in the body. Scientists
estimate they may move more
than 100,000 times a day!
• The largest muscle in the body is
the one you sit on!
Types of muscles
Cardiac
Heart
Skeletal
Smooth
Voluntary
Involuntary
Remember:
Smoothinvoluntary
When one muscle
contracts (flexes),
the opposite
muscle relaxes.
Exploring the Muscular System
• You will work as a group at your table.
• Each table will use 1 laptop.
• Go through and read the information on each
slide and follow directions.
• At the end of the presentation, you will
complete 4 muscular labs.
• Have fun!
Watch a quick movie about muscles.
#1 – How strong are you?
• Complete the following exercise to measure
the strength of your arms.
• Make sure you measure in Kilograms.
1. Biceps: Hold the measuring scale under
the desk and push up (make sure you are
able to see the number of Kilograms).
2. Triceps: place scale on desk; press with
your hands – not your arms.
3. Forearms: Grab scale as hard as you can –
do not use your thumbs
#2 – How long can you last?
1. Stand up.
2. Each person take 1 textbook.
3. When the timer starts, hold the
textbook in your hands, palms
should be flat and facing up;
arms should be straight and held
in front of you at shoulder

you were able to hold the book

Timer
3 – Wall sits
1. Get into a sitting position against a wall
so that your back is flat against the wall
and your thighs are parallel with the
floor.
2. Time how long you can remain in this
position.
3. Repeat 3 times.
How did it feel when you tried to walk
after this exercise?
The funny feeling in your legs is muscle
fatigue which is when the muscles are
tired and lack energy.
Timer
#4 – Clothespin Squeeze
1. Hold a clothespin between your
thumb and your index finger.
2. Count how many times you can
squeeze a clothespin in one minute.
3. Repeat 2 more times in a row.
4. Record the number each time
What did you notice about the number of
times you were able to squeeze the
clothespin each time?
Timer
