Students in Mr Hillâ€™s year 8 class are studying a topic on respiration. They have learnt about how the composition of the air we breathe in is different to the air we breathe out. They have also learnt about aerobic and anaerobic respiration.
During a lesson earlier this month they examined a real pigâ€™s heart and lungs to see how they worked together to transport oxygen around the pigâ€™s body. Students blew down a tube into the pigâ€™s lungs to see how they inflated as the pig would breathe when it was alive.
