On Friday the 17/1/20 Lismore Science came and taught us about the digestive system. At first we poured in rice crispies to a bowl.Then we tried to chop them up but it was too hard so Rosanne said to pour in cows saliva, it was fun but so weird, then she said how it goes down the esophagus. After that it went into the stomach and we poured in water with food colouring in it to represent acid and then we put it 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, after that it goes into the small intestine for a four hours then it goes into the large intestine. After all that the waste is left so it comes out in the toilet. After break we learned chemistry- about bases and acids, the acid is red and the base is blue. The teacher had boiled red cabbage to show us if the liquid was base, neutral or acid.She gave us each two liquids to see if it was base or acid. I got one acid and one base. When you mix acid, red cabbage and base it makes a chemical reaction. It was all so interesting and fun.
