Year 4 - Science

Waste creation and pollution (Climate change and sustainability)

Living things and the environment

Unit Summary

This unit focuses on grouping living things and using classification keys to identify and name them in various environments. It explores how environmental changes can pose dangers to organisms. Emphasis is on asking questions, collecting data, and using evidence to support conclusions.

Lesson Summary

You will learn to describe some negative effects of waste creation and pollution and suggest some ways to reduce it.

Key Notes

  • Environments can change in a negative way as a result of the actions of humans.
  • Larger populations can create greater amounts of waste and pollution.
  • The cars we drive, the products we use and the crops we eat can all contribute to pollution in the environment.
  • Individuals can change the way they live to reduce the impact of waste creation and pollution on the environment.
  • Industries can change the way they work to help create less waste and pollution.

Vocabulary To Learn

  • environment: An environment is the surroundings of a living thing, including other plants and animals and the conditions they live in.
  • impact: The impact of something is the effect it has.
  • waste: Waste is any material or substance that is no longer needed or usable which is generated as a result of human activities.
  • pollution: Pollution is the introduction of harmful materials into the environment.
  • industry: Industry is the companies and activities involved in the process of producing goods for sale, especially in a factory.

Common Mistakes To Avoid

  • Some pupils may not understand the impact of an increased human population on plants and animals.

3 Quick Questions (With Answers)

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

Environments can change in a negative way as a result of the actions of humans. Larger populations can create greater amounts of waste and pollution.

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

An environment is the surroundings of a living thing, including other plants and animals and the conditions they live in. Include the word in a full scientific explanation, not as a single label.

3. Correct this common scientific misunderstanding.

Mistake: Some pupils may not understand the impact of an increased human population on plants and animals. Correction: Discuss, using examples on the slide deck, all the repercussions of increased population. If possible, include an example relevant to their location to help them see it first hand.
