The D.I.Y. Science series contains some of our favourite experiments for kids to try at home. They are designed to help primary school teachers and carers inspire a child’s curiosity in science. It’s time to get hands-on.
This episode shows what happens to our lungs when we breathe and how our respiratory system draws air in and out of our body. You will learn how to build a model lung that can actually breathe using resources that you can find around the house.
It is best suited to year 8 and 9 biology students who are learning about the respiratory system. It also mentions air pressure and how this results in air being drawn in to and expelled out of our lungs.
