States of Matter

We’ve been learning about the processes involved in the water cycle and about how, when exposed to heat or cold, materials can change their state. We brought this to life in the classroom when we created a water cycle of our own. We were able to observe heat evaporating water to create water vapour. Later, we saw how the ice cubes created a cold atmosphere. When the water vapour (gas) came into contact with this cold air, it changed state back into a liquid. We could see the condensation on the cling film.

Our next investigation involved testing whether different materials had an affect on the melting point of a solid (ice cubes). Here we are observing changes and measuring the time the ice cubes took to melt.

Today we observed whether states of matter change when they are heated. We heated three different types of chocolate and recorded how long it took them to become a liquid and at what water temperature.

States of Matter

Solids, Liquids and Gases

We began our new topic by sorting and classifying a range of materials by our own criteria.

Next, we had to guess which criteria had been used to sort these materials. We successfully identified liquids and made lots of suggestions for the other two groups.
