S3.8.7 For the adult
Energy from food
Why am I so hungry after playing all day?
What this chapter teaches
Food energy is counted in kilojoules, and foods differ a lot in the energy they hold in the same weight. People who are more active move more energy out of their bodies, so they need more food energy. Growing bodies need energy too.
Three questions to ask
There is no one right wording. Listen for the idea.
- Which food in the table has the most energy in 100 grams?
- How would you find the energy in 300 grams of bread?
- Why does someone who works hard all day need more food?
After the chapter, the learner can
- Compare the energy in foods using a table in kilojoules
- Explain why active people need more food energy
What they copy into their notebook
Food is a chemical store, counted in kilojoules. Foods hold different amounts. Active people move more energy out of their bodies, so they need more food energy.
