Within the science area we have been discussing the properties of materials, particularly learning about the difference between solids and liquids.
While playing with ice the other day we started discussing the properties of snow, hailstones and rain. We decided to make our own snowballs and experiment with various ways of melting them.Ā We created our snowballs by making gloop and then freezing it inside plastic baubles.
When we took them out of the freezer, they were so cold and frozen we couldn’t even open them and had to put them in the bowl of hot water to start the melting process.
Once we got the snowballs on to the trays the children experimented with dripping hot water on top of them. One of the children realised that if he made a hole and put water inside the hole it speeded up the process. His friend decided to make the holes and he could squeeze the water in. Great team work! The other children realised they could use the tools to help chip away at the snowballs.
Throughout this experience we discussed how the freezing and melting process changes water from a solid to a liquid and back again. After they were all melted we had a great time playing with the gloop and getting messy!
