Primary 7 have been looking at the Respiratory system. In order to investigate and attain a scientific understanding of the Respiratory system, we have been conducting experiments looking at the impact of exercise on our breathing.

We began by assessing how big we could blow the balloon up in one breath. Then we compared it to how we could blow up a balloon after doing star jumps or jogging on the spot. We used a string to measure the difference.

We were all able to make scientific predictions, review these and apply our findings to facts.

We all loved this fun experiment and now know the importance of our lungs, breathing and respiratory system
