GL137 - Looking at organs inside the chest (known as a “pluck”) in primary schools

Having a close look at a pluck can help children to gain an appreciation of the range of organs found in the mammal’s body. Children can identify the organs and compare their size, colour and structure. Children can also see how the organs are connected by blood vessels, and so inter-relate to each other.

Examination of a pluck also gives teachers an opportunity to mention that the heart and lungs work together in respiration.

Studying a pluck can give children an appreciation of how the organs are arranged in their own chests.

GL136 - Looking at (dissecting) kidneys in primary schools

Dissection can help children to gain an appreciation of the range of organs found in a mammal’s body. It also gives teachers an opportunity to relate their teaching of the circulatory system to the functioning of organs in the body.

Studying the kidney gives children an opportunity to relate an internal bodily organ to a product that they can see (urine).

This practical is a simple, safe method to observe how everyday indicators behave and could provide opportunities for independent working, investigation skills or encouraging effective teamwork.
