      The 3 Rs (non-statutory - Climate Change & Sustainability)

      Lesson details

      Learning outcome

      I can describe materials and objects that can be reduced, reused and recycled.

      Key learning points

      1. Recycling is one of the 3Rs: Reduce, Reuse, Recycle.
      2. Rubbish needs to be sorted into different materials before it can be recycled.
      3. Plastic, glass and wood can be recycled and made into new and useful things.

      Keywords

      • Landfill - Landfill is where we get rid of waste by burying it in the ground.

      • Reduce - Reduce means using less of things.

      • Reuse - When we reuse something we use it again.

      • Recycle - Recycling is when we collect and sort our rubbish instead of throwing it away. These items then get changed into something new for us to use.

      Common misconception

      Children may instinctively classify objects by observational similarities or through knowledge of use rather than by the material from which the objects are made.

      Reminders of the difference between the object, what it is used for, and the material it is made of. Use of real-life objects for children to explore to aid this understanding.

      Teacher tip

      Many local authorities and waste management companies offer free school recycling visits with information and tips that pupils can use in everyday life.
