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?

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.

During exercise you muscle cells need more energy. They get it from aerobic respiration of the glucose dissolved in your blood
Glucose + oxygen carbon dioxide + water (+ energy)

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.
