We are scientists!

Today year 3 started to learn about chemical reactions in science. We experimented with hydrogel and salt, to find out what would happen when we mixed them together.

We learned that Hydrogels are very clever – they can change their shape depending on what is happening to them. Through exploring with the Hydrogel in the hair gel, we discovered that it turned from a solid in to a liquid when the salt was added!  We thought it was very exciting to see a real chemical reaction in our classroom, with things we see around us every day.
