    By Kate Dance “Torching Tiny Teddies” Energy Efficiency Experiment Aim: To test the energy efficiency of a tiny teddy in kilojoules by burning the tiny teddy beneath a test tube of water. The water temperature is then measured to see how efficient the transformation of energy is. It is important to see how efficient the transformation is as it will give an indication to whether burning tiny teddies would be an efficient source of energy. Hypothesis: It was hypothesised that the temperature would
