Lismore Science

On Friday the 17th of January 2020 Lismore Science came and taught us about the digestive system. First we put rice crispies in a bowl we tried to crunch them with our spoons but it didn't do it that well so we got 2 glasses of water to represent saliva it was way easier to crunch them with our spoons this time. Then Lismore explained how it goes down the esophagus, after that it goes into the stomach and we poured in water with food colouring in it to represent acid and we put what we had after that in a plastic bag and squished it to represent the stomach eating it. After that it went in between the stomach and the liver and that creates bile, then it goes into your small intestine for a few hours. Then it goes in your large intestine and it comes out into the toilet. Then we had our lunch which I could barely eat because I was still thinking about the rice crispies. Next we did chemistry. We learned that if you boil a red cabbage and put it in a liquid it will show if it is a neutral, base or acid; there is a pH scale from 1 to 14. 1 to 6 is acid 8 to 14 is base and 7 is neutral. Lismore gave us a sheet with a pH scale on it and a few containers with liquid and we had to put them in order, it was really fun and I hope they come next year.
