Activity #1 – Which one is Heavier
1. Work in pairs of 2
2. One person will hold the two cups labeled A and B while
closing their eyes!
3. Each cup will weigh about the same
4. The other person will then take the cups away and add
weight to one of the cups. (use the pennies at your table but
keep track of how many you add)
5. The person closing their eyes will have to guess which cup
now weighs more.
6. Continue until the person can tell which cup is heavier.
7. When done, remove the extra pennies for the next class.
Class Discussion: How much extra weight was needed for the
muscles to send the message of more weight to the brain?
***In your notebook, write down your partners name and how
many extra pennies it took to send the message to the brain.
Activity #2 – How strong are you?
Working with a group complete the
following exercise to measure the
strength of your arms.

you can – do not use your thumbs
***Each person must document their
scores on their papers.
Repeat each exercise 3 times.
Now let’s measure
muscle fatigue
Muscle Fatigue
• What causes muscle fatigue?
• Can you do anything to prevent it?
• How long can your muscles endure?
• Muscle fatigue is a muscle’s reduced ability to
generate power and force.
• In other words, when your muscles feel tired
and can’t do a task anymore, you are
experiencing muscle fatigue!
Activity #3 – How long can you last?
1. Stand up.
2. Each person take 1 textbook.
3. When the timer starts, hold a
World History textbook in your
hands, palms should be flat and
facing; arms should be straight
and held in front of you at
shoulder length.
4. Sit down when your arms get
too tired to hold the book out in
front of you.
**In your notebook, document the
amount of time you were able to
hold the book out in front of
you.

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.
