It’s science week at Cart Mill and we have been discussing the properties of water and the effect of the cold. We found out during our visit from Williamwood that water is a liquid and that it can move about in a container.

We gathered some containers and used scissors to cut up some foliage to add before we poured the water in, then off to the freezer we went.

The next day we were surprised by the appearance of the water “it’s gone hard” “it’s cold” The water had changed from a liquid – something that can move about in the container, to a solid – something that doesn’t move in the container. When the temperature of the water becomes very cold (below freezing) it turns to ice.

The children decided to add colour to the water, so, very carefully we used droppers to add some dye “it’s getting  darker”

The children wondered what would happen if we added more water to our ice. We added another layer of foliage and coloured water on top of our ice. The water sat like a different layer on top of the ice, it was very strange, the water moved but the ice didn’t! We all wondered what would happen if we put the container back in the freezer so off to the kitchen we went with our containers. What will happen? Watch this space…
