Can you stick the target and word sheets
for the next topic in please?
This lesson
• Know what “fit” means
• Know how exercise affects pulse rate and
breathing rate (and why)
• Know which organs systems work togther
to release energy from food
• Know muscles release energy from food
by aerobic respiration
Fit?
Fit
Being fit means your body can cope with
the activities you need to do

Being fit means your body can cope with

To stay fit you should eat a balanced diet,
exercise regularly, avoid smoking, avoid
alcohol and avoid drug abuse.
Let’s see
how fit
you are!
How fit are you?
• In pairs one of you is going to run on the
spot for 2 minutes
• You will then measure your heart rate over
a period of 10 minutes

How to measure pulse
• Check your pulse at your wrist.
• Use two fingers - your index and middle.
• Count how many beats in 20 seconds and
multiply that number by three to get your
heart rate.
Finish for homework – due next
Tuesday too!
• Graph
• Conclusion: Two sentences describing
what you have discovered
During exercise
Your breathing and pulse rate increase
because your cells need more glucose
and oxygen for respiration.
Can you copy
this please?
Exercise
During exercise you muscle cells need more
energy. They get it from aerobic respiration
of the glucose dissolved in your blood
Glucose + oxygen
Reactants
carbon dioxide + water (+ energy)

All systems are go
The respiratory system supplies the
oxygen and removes the carbon dioxide

What can you
remember about the
lungs?
Let’s try a
lung sheet!
All systems are go
• The digestive system provides the glucose
All systems are go
• The circulatory system carries the glucose
and oxygen to the cells and the carbon
dioxide away to the lungs.
