Year 4 - Changing States of Matter

Date: 1st Oct 2024 @ 3:42pm

This week, we looked at changing states of matter. This half term, we have been focusing on solids, liquids and gases. So today we looked at what the terms are called when they change from one to another. We started the lesson by holding a piece of chocolate (solid) in our warm hands. This made the chocolate melt and this happened because we increased the temperature. Later in the lesson, we looked at whether salt would make ice melt quicker. It did because the salt and ice melt to make saltwater and that has more particles in it.
