Lesson Planning

Teaching

• Know the diaphragm is used in breathing and the lungs transfer oxygen to the blood.
• Know that muscles need more oxygen to work hard and this affects breathing rate.
• Plan and conduct a fair test to answer a question.
• To choose how to display data to look for a link and communicate findings.

Activities

1. Learn how the heart and lungs get oxygen to the muscles where it is needed to make energy.
2. Plan and carry out an investigation in groups that attempts to answer a scientific question - Do people who exercise a lot get their breath back more quickly after strenuous exercise? (Yr3) or Do people who exercise a lot pant less after a burst of strenuous exercise? (Yr4)
3. Display and interpret data collected and seek to explain findings.

Investigation - fair testing, pattern seeking
The team get out of breath quickly as they run up and down the pitch. They want to know why and what they can do about it. Learn how the diaphragm is used in breathing to get oxygen into the blood. Plan and carry out an investigation to answer a health and fitness question.
Year 3 - Learn to take a pulse. Measure heart rate before and after exercise.
Year 4 - Plan and carry out an investigation to see if people who exercise regularly pant less.
