MUSCLE MANIA
Time to do a physical experiment!
In pairs you need to measure your breathing before and after doing some exercise in the
park. To measure your breathing your partner has to put their hand on your shoulder and
count how many times your shoulder goes up and down as you breathe for thirty seconds.
You can also use the pulse meter to measure your pulse and the percentage of blood
loaded with oxygen

Whilst you were doing your exercises your body was both ventilating and respiring.
Talk in your pairs about what was happening to your lungs whilst you were breathing in and
out.
How is respiration different to ventilation?

Put the word equation for respiration into the correct order using the words below
____________ + _____________
________________ +___________ (+________)
Oxygen, water, carbon dioxide, energy, glucose
Plants respire too....respiration and photosynthesis are opposites.
When do plants respire?
When do plants photosynthesise?

photosynthesis? Or are they

Think back to how your body was moving during your exercises.
It is your flexible joints that are allowing you to move. What else do you use to move your
bones attached by these flexible joints?
What are 3 parts that are in your joints?
With your partner create an exercise that moves one of your
 Hinge joints
 Ball and socket joints
How are muscles attached to your bones?
Can your muscles push and pull your bones?
What are antagonistic muscles?
 Now create an exercise that moves a pair of your antagonistic muscles.
Be ready to share your 3 exercise moves with your class to create a big exercise routine!
