Energy in Food

A series of free Science Lessons for 7th Grade and 8th Grade, KS3 and Checkpoint Science in preparation for GCSE and IGCSE Science.

Investigate the energy in food
The energy content in a food sample can be measured using simple calorimetry.

Calorimetry
To carry out this experiment, you need to:

1. Pour water into a boiling tube.
2. Record the starting temperature of the water.
3. Record the mass of the food sample.
4. Heat the food until it catches fire.
5. Heat the water using the flame from the burning food.
6. Record the final temperature of the water.
7. Record the final mass of the food sample.

Exercise:
Use a table to record the data for the different food samples.
Draw a bar graph to show the results.
Comment about results.
