In room 5 we did a lung experiment to test our lung capacity.
We did this to see if we got the average lung capacity to see if we are fit.
We did it with plastic tubing [make sure it’s clean], a large plastic bottle, water and a basin.
You put the water in the basin. Put your hand on the bottle to stop water from escaping. Put the plastic tubing at the end of the bottle. Take a deep breath and blow as much water as you can through the tubing.
Measure the amount of water that pushed out of the bottle to find your lung capacity.
