Year 5 were lucky enough to have Ms Guram from Highbury Field School come to Gillespie and work with us in Lab 13. We had already completed some learning in Science and Maths about the heart and were ready to find out more.
We began the session discussing what we already knew before being given a sheep’s heart to look at. We had to touch it, look carefully at it whilst trying to decide which was the front, back, top and bottom. We then pushed our thumbs in to the arteries where we could feel that one side was definitely thicker than the other.
We were asked to predict then discuss how we could work out how much blood each side would hold, so using a syringe we filled each side with water. This was quite hard to do because the hearts were very slippery to hold.
Ms Guram then showed us how to dissect the heart – she certainly made it look easy! We worked in pairs – one holding and one cutting. Once we had managed it we could see inside the heart, we measured both side of the heart, then cut down the sides to see the heart strings and the valves. The heart strings were very strong!
Ms Guram then brought out a ‘pluck’ which is the windpipe attached to the lungs, liver and heart. She dissected the windpipe to show us the ridges and the lungs to show us how the air travels around inside it. It was really interesting but we were glad we didn’t have to dissect that as well!
The lesson was amazing and we learned lots of new things and skills. We used our learning to make models of the heart with our partner. If you look closely, you can see that some of us tried to add in valves and heart strings.
