Today we found out how the lungs work. We looked at some lambs lungs with Year 3. We had to put on aprons and gloves and we worked in groups.
To see how the lungs inflate we used a balloon pump to blow air into the lungs. We put the balloon pump into the trachea and we saw the lungs inflate with air. We were surprised how big the lungs were when they were inflated and how small they went when they were deflated.
One group could clearly see the one of the bronchioles and it looked like a tree. We cut the lungs open and we could see the tubes that lead to the air sacs (alveoli). Another group was able to put their stick through the trachea and found their way into the lungs.
The lungs felt wet, slimy, cold, squishy, and spongy. The trachea felt harder than the lungs and they felt bumpy. On the back of the lungs we could see the tissue that would connect the lungs to other organs.
We all joined in exploring the lungs and here is what we thought:
I thought exploring the lungs was disgusting but okay.
I thought it was weird but awesome because we can see what lungs actually look like. It was amazing to see how our lungs work hard every day.
It was inspiring to see how the lungs would work. I thought the lungs would be small but today I found out that the lungs were really big to pump a lot of oxygen around your body. I learnt today that our lungs need a lot of oxygen from the air.
It was interesting feeling the lungs because it felt smooth in some places and bumpy in other parts.
It was interesting looking at what’s inside us. I liked it when I put the stick through the trachea into the lungs.
It was interesting how squishy our lungs are.
It was interesting when you blow the lungs up, they change colour. It is satisfying to see how your lungs breathe.
It was amazing to see how our lungs would work.
It was interesting because I saw the holes in the lungs.
It was strange that only one of the lungs inflated.
The bronchioles looked a bit weird but I am a bit squeamish.
I enjoyed touching the lungs because they felt funny and squishy.
