We looked at how water changes when you boil it in a kettle to become steam and found that a cold tray worked like magic to change it back to water again.
We also made frozen 'ice hands' by filling up rubber gloves with water and then putting them in the freezer.
We explored ice cubes and how they melt when they get warm. We noticed the water still feels really cold when it drips on your hands though!
We then made wibbly wobbly jelly of different flavours and colours. the jelly cubes needed hot water to dissolve them.
