Year 4&5 investigated scientific changes in solids, liquids and gases. They investigated the properties and qualities of candles which differed in size, shape and colour and looked at the changes that occured in different parts of the candle and matches during heating, burning and cooling. They also watched as the teacher created two shorter candles from one long candle by melting through the wax at the half way mark and burning the wick at the central point. Fascinating!
