Energy in food

Perhaps our most immediate connection with energy is the energy in our food. Releasing the energy by burning gives an insight into the total energy available in a sample of foodstuff.

Experiments
  • How much energy is there in food?
    Burn samples of food and use the energy released to heat a sample of water. Estimate energy in food by calculation from temperature increase in water.
