The impact of exercise on the heart - A year 3 investigation

During the course of the week, Team Bullard have been studying the cardiovascular and circulatory system as part of our unit 'How We Live'.

After making our predictions about what sort of exercises we could test and running through our method and equipment set up, we began to form groups to run our tests and record our results.

We found that the more we moved, the harder and faster our hearts beat to deliver oxygen to our muscles.
