Today, we investigated reversible changes in Science. We looked at how we can change water by heating and cooling it. First of all, we looked at ice. We found out that ice is a solid and that the particles are tightly packed together. We used pupils in our class to show that the particles in a solid cannot move.
We then held an ice cube in our hands. It felt cold and slippery. After that, we carried out an investigation to find out the best place in the classroom to melt the ice cube quickly. We found out that it is important to keep our test fair!
