Thank you to the parents who handed in empty plastic bottles for our experiment today.
This week our focus was on the function of our lungs. In P5i we did a lung capacity experiment where we recorded how much air we could breath in and blow out. Quite a few got out of puff rather quickly. But too much laughing could have been to blame.
This afternoon we proved that 4 does go into 3 when all P5s were spilt into 3 classes to enable us to perform another experiment. This time we used the empty bottles to show how our lungs function. Some pupils were more successful making fake lungs than others. They don’t make plastic bottles like they used to and many just buckled when children tried to pull a balloon over the ends. However, they had fun trying.
Here are some of their efforts in both experiments.
