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 the positive impact of reforestation and recycling on the environment.

Key Notes

  • Positive impacts on environments can include reforestation and recycling.
  • Reforestation is when forests are re-grown in areas that used to be populated by trees.
  • When we recycle, we collect and sort rubbish instead of throwing it away. These items get changed into something new.
  • Recycling and reusing objects can prevent rubbish going to landfill and having a negative effect on the environment.
  • Environmental scientists are constantly studying and finding ways to protect changing environments.

Vocabulary To Learn

  • reforestation: Reforestation is the act of planting trees on an area of land that has become empty or spoiled.
  • recycling: Recycling involves sorting and treating rubbish to produce useful materials that can be used again.
  • reuse: When we reuse something, we use it again.
