Solids Liquids and gases

compare and group materials together, according to whether they are solids, liquids or gases

Although most children will be able to group materials according to their state, this provides a really good opportunity to apply a theory to explain a phenomenon they are already quite comfortable with.

Heating and cooling

observe that some materials change state when they are heated or cooled, and measure or research the temperature at which this happens in degrees Celsius

Again, changes of state will be familiar to most children so this topic is mainly about giving names to those processes and looking at the science behind them.
