| Figure 1: Apparatus (but is missing the thermometer in the boiling tube) |
- Get 5 different food samples. For this experiment, let’s say crackers, apple, cornflakes, dried tomato and tofu. (We don't want to be killing animals...no thanks!)
- Prepare the following apparatus: A utility clamp holding a boiling tube with a thermometer in it. Have a skewer and a bunsen burner at the side.
- With each food sample, put it on the skewer and take the SAME amount and set fire to it. Place it directly underneath the boiling tube filled with water. Record how much the temperature has risen.
- Empty the tube and take the SAME amount of water as before at the SAME (room) temperature.
- Repeat steps 3 and 4 for all the food samples. Now calculate the difference in temperature.
- The more the temperature rose, the more energy the food sample has. :) To plot a graph, plot a bar graph with the x axis labelled with the types of food you used and the y axis labelled with percentage % change in temperature (yay…more calculation…)
