We have had a great week investigating solids ,liquids and gas. We know that water is a solid when it is cooled and a gas when it is heated. We also discovered that we can turn the steam back to water by cooling it and the water back to ice.
We discussed whether the same is true for wax. We know that when heated it becomes a liquid but when we looked at the two candles we realised that it doesn’t return to its exact form and that some of the wax disappears. Where does the wax go ?
Noah thought it dissolved and Max thought it went into the air. Its a mystery that we need to investigate further.
