Today Primary 4 completed a science experiment to see how much air we have in our lungs. We had to blow into a balloon. We found out that we are all different and don’t have the same lung capacity.  Here are some photographs of us during and after the experiment. It was good fun!

Some amazing facts we have learned:

–  an adult breathes enough air to fill 1,000 party balloons a day.

–  we breath around 20,000 times a day.
