Year 3 - Science

Sustainable sources of food (non-statutory Climate Change & Sustainability)

Healthy eating

Unit Summary

This unit covers how animals, including humans, obtain nutrition from their diet, emphasising the need for the right types and amounts of food. It involves asking questions, gathering and presenting data, using scientific language, and interpreting evidence to answer questions and support findings.

Lesson Summary

You will learn to explain why it is important to produce and harvest food in sustainable ways.

Key Notes

  • As the human population size on Earth increases, more food will be needed.
  • To make sure there will be enough food to meet the increasing demand, we should produce food in more sustainable ways.
  • It is better for the environment to buy local food in season.
  • You should buy what you plan to consume, to avoid unnecessary food waste.

Vocabulary To Learn

  • population: The population is the total number of something living in a particular area in a particular period of time.
  • sustainable: If something is sustainable, it meets the needs of people now without having a negative impact on the needs of people living in the future.
  • environment: The environment is the surroundings of a living thing, including other plants or animals and the conditions they live in.
  • in season: Food that is in season is only harvested at that time each year.
  • harvest: When you harvest a crop, you cut and collect it from where it is growing.

Common Mistakes To Avoid

  • Pupils may think that all food is produced in the same way.

3 Quick Questions (With Answers)

1. Explain the scientific idea in this lesson using two key points.

As the human population size on Earth increases, more food will be needed. To make sure there will be enough food to meet the increasing demand, we should produce food in more sustainable ways.

2. Define this scientific word and use it in context. 'population'

The population is the total number of something living in a particular area in a particular period of time. Include the word in a full scientific explanation, not as a single label.

3. Correct this common scientific misunderstanding.

Mistake: Pupils may think that all food is produced in the same way. Correction: Explanation of how foods can be produced and harvested in different ways with differing environmental impacts.
