Lesson details
Key learning points
- Different foods provide different amounts of energy.
- The amount of energy provided by different foods can be investigated and compared by burning them.
- Burning foods can heat water and the temperature change of the water measured.
- The mean temperature change can be calculated from repeat measurements.
- Energy provided by the food (J) = mass of water (g) x rise in temperature (°C) x 4.2
Keywords
Temperature change - The difference in the starting and end temperature of a substance.
Mean - An average of several measurements, which is calculated by adding them up and dividing by the number of measurements.
Mass - The amount of matter in an object.
Variable - A variable is a factor that can be varied or measured in a science experiment.
Common misconception
Control variables make it a fair test.
Control variables need to be kept the same to make the investigation valid.
