In Science this week we looked at how heat can make things expand (get bigger) and how the cold can make things contract (get smaller).
We observed our environment on the way to the Science Room and noticed that all the concrete in the school had expansion joints to help allow for this expanding and contracting.
We then conducted an experiment to observe how the heat and cold can make air expand and contract by placing a balloon over a water bottle and placing it in boiling water and water filled with ice.
The Year 3 Scientists all seemed to make correct predictions and their hypothesis was confirmed during the experiment.
Here are some photos of the bottles after they had been placed in hot water. The ‘scientists’ found this part of the experiment particularly funny (I’m not sure why…)
