Primary 2 have been learning about solids, liquids and gases as part of their science topic.  They enjoyed identifying different things in the classroom as the different types of matter. Today we looked at how matter can change state when a chemical reaction takes place. Each group had their own ice melting experiment to determine what conditions made ice melt the fastest. The different conditions were: salt, warm water, cold water, direct sunlight, use of a radiator and no change. We found out that the bowl of ice that had no change melted the fastest. We believe this was because, due to the sunny day, the classroom held in the heat similar to a greenhouse, causing the ice to melt fast. We had great fun investigating!
