We have been very busy scientists recently. We have been learning about solid, liquid and gas, and how substances can change between each state.
Here we are carrying out an experiment to change solid ice into liquid water using heat energy from our hands. I think the ice was pretty cold!!

We also carried out an experiment to investigate what solid substances (salt, sugar, flour, icing sugar) will dissolve in a liquid. At first, we used cold water only. We then discussed variables we thought would help the dissolving process (heat and stirring):
