This week, Y4 have been designing and setting up a number of experiments to see how materials change over time. They have been looking at how different materials can melt, freeze, evaporate and condensate. They have made their predictions and have already gathered some results!

What will happen to the water in the uncovered glass? What will happen to ice cubes at room temperature? What will happen to ice in a fridge? Y4 are finding out! 

Children also conducted a comparative test to see if the mass of an ice cube affects the time it takes to change state. Most correctly predicted the result!

Grace and Alisha predicted the ice cube with the greatest mass would take longer to become a liquid!
