This week my reading group has been using the sweet and sour kit. In this blog post you will show you what we did in this kit.
On Wednesday we did a activity called sweet and sour. We were exploring the chemicals to see what pH level it was.My reading group first got a tube and put some water in it and sat back down. Then we got a spoon and put some baking soda on it and got a dropper got so water in the dropper and put it on the spoon. Then we put the indicator paper in the liquid and then a colour would tell you if it is a acid or a base. We used a indicator paper to see if it was. We also were seeing if it was a acid or a base we had baking soda, icing sugar, flavour raro,citric acid and vinegar. We found out that 2 of them were bases and the rest were acids.
In our 3 experiment we made a pH indicator with a red Cabbage that came with the box. We first riped a leaf of red cabbage and put it in a plastic bag. After that we went to go get some hot water in our bag. We had to squished the bag so that the cabbage went every were. Then we put some of the cabbage into the test tubes. Then we put the test things into the cabbage water to find out what was a acid or a base they changed colours instently. We figered out that 2 of then were acids and 2 of them were bases. I was surprised that it was a pH indicator.
Hi Bjorn,
ReplyDeleteI like how you wrote all the detail of the names and what you were doing. In class this looked really fun. Maybe you could check your punctuation and spelling before publishing.
