The changing state of water

Date: 18th Jan 2023 @ 3:34pm

In science, we have been learning all about solids, liquids and gases. A few questions really sparked good discussions, such as: Is a sponge a solid? or Is sand a liquid?

We have also been investigating what happens when water changes state. The children came in after break to find ice hands on their tables!! After having a little discussion, they then planned and carried out their own investigations. Some groups chose to observe the temperature changes of the water, others chose to observe how much liquid was left in the tray or how much water was left at the end. The children's results varied, and, as a class, they decided that they needed to ensure that some of the variables were kept the same to ensure that it was a fair test- this is something we will definitely do next time.

After that, we then discussed what happens when a solid turns into a liquid, a liquid into a gas, a gas into a liquid, and a liquid into a solid. The children now know what evaporation and condensation are. To help them understand this, they had 3 different experiments to explore: ice cube investigation, reversing changes and salt and ice. 

It is safe to say that this lesson has definitely inspired some children to be future scientists!
