Year 6 Science – Dissection

The Year 6 class have been putting their biology work to the test in two dissection practical lessons.
They first learnt all about the heart, and they are now studying the respiratory system.
Each group worked on a pair of lungs and a trachea, noticing the cartilage and taking samples of lung, liver and muscle tissue.  The children discovered that the lung tissue floated when placed in water, in contrast to liver or muscle samples that sank.
Carefully using a straw to blow air into sheep lungs, they observed the air inflating the alveoli, where oxygen enters our blood.​
The class really enjoyed the hands on session, and their teacher was really impressed with their skill and concentration.
