Carbohydrates are compounds of carbon, hydrogen and oxygen. Starch and sugar are carbohydrates and they provide us with the energy our bodies need.
The aim of this experiment is to show that heat energy is produced when starch and sugar are burned and to compare how much heat energy each produces.
We will burn flour as the ‘starch’ carbohydrate and icing sugar as the ‘sugar’ carbohydrate. The energy produced when they burn will be used to heat water. The rise in temperature of the water will give us some idea of how much heat energy has been produced.
