This morning we did an experiment. The experiment was called elephant toothpaste.
First we got the equipment and went outside the hall. Next, Mrs Taylor put hydrogen peroxide, green food colouring and dishwashing liquid in a bottle. Then she put water and yeast in the bottle. Finally it started to rise. There was a chemical reaction and green foam went everywhere.
That is a great experiment! Did you like watching the foam come out, Chase?
ReplyDeleteYes, but it went up slowly so we had to wait for a while for it to get to the top of the bottle.
