Following that, we planned an investigation to see if we could prove or disprove this statement,
After exercising, your pulse rate will increase by 20 beats per minute.
The children decided what exercise they were going to carry out and how long they were going to exercise for before taking their pulse rates. To make sure the results were accurate they planned to repeat the exercise and pulse rate recording 3 times and also make sure they had rested properly between each repetition.
Whilst some children carried out their investigation outside, the rest of the class drew bar graphs to show the resting pulse rate information we had gathered earlier and then they swapped over.
Below you can see us carrying out our investigations, taking pulse rates and then finding the averages.
