Adaptive teaching

Pupils needing extra support

Could use a pulsometer, smartwatch or data logger to measure heart rate; should use the Activity: Investigating exercise and heart rate: support version; could watch the Pupil video: Investigating exercise and heart rate or the Resource: Investigating exercise and heart rate method to remind them how to carry out the experiment.

Pupils working at greater depth

Should plan how to extend the investigation to consider the effect of a broader range of exercises or factors on heart rate (such as gender or age); could choose an extension activity relating to heart rates and the circulatory system from the Resource: Stretch and challenge: Circulation and health.
