On Friday the 17th Rosanne from Lismore Science came to teach us some science. First we did digestion, we started crushing rice crispies, it was quite hard because they were dry so Rosanne gave us some saliva which made it easier. Then she told us the food goes down the esophagus and then into the stomach (aka plastic bag) where we added gastric acid. We squished it around in the plastic bag to mimic the stomach churning. After that we put it back in the bowl and added bile which is made in the liver and it kills the acid from the stomach we also added pancreatic juices from the pancreas, then it went through the small intestine and then through the large intestine where we put it in a leg from tights.
We then had to squeeze out the juices and what was left was waste or the scientific name feces.💩
After lunch we did chemistry, we made a PH scale by adding red cabbage juice to different liquids to see whether they were acids or bases. We also added baking soda to vinegar and there was a chemical reaction. It all started to bubble and expand .
Then we put a rubber glove with baking soda in the fingers over a cup with vinegar in it. When we poured the baking soda in the glove inflated, we proved we made gas.🤩😍😛
