We have done an experiment on dissolving. It was fun and interesting. We mixed flour, salt, sugar, sand and chalk with water.
Each group chose either apple juice or vinegar to replace with the water.

Someone from each group came to the tap and filled the test tube to the amount that their group decided. Some filled the tube to 30ml but other people used more water. Then we took one tea spoon of a substance and poured it into the water and then we stirred for 30 seconds.

We took the spoon out and we saw if the substance had dissolved but most of the substances did not dissolve.

Thank you for reading our class blog.
