Topic: Ethics and the Environment – Exploring ways to increase our plastic recycling.

Learning Outcomes

  • Children will learn how long different plastics take to break down.
  • Children will learn alternatives to using plastics
  • Children will learn what an Eco brick is , its uses and benefits
  • Children will create an advertisement for an Eco brick

 

Introduction

Children will brainstorm what plastics they use in their daily lives and we will discuss how we dispose of these plastics. This will be followed by pair work on alternative disposals for them. We will watch a short video on how long plastics take to decompose.

Teacher will show them an EcoBrick and ask for opinions on it.

Watch EcoBrick video on Cork Seal Sanctuary

Create message to deliver to other classes promoting use of them and how to set up a positive plastic environment in your class.

 

Development

 

Create message to deliver to other classes promoting use of them and how to set up a positive plastic environment in your class.

Make chart to monitor how many days plastic free and EcoBrick advertising poster.

 

Plenary

Deliver message to other classes along with an empty two litre bottle.

Continue to use EcoBricks .

Continue to update plastic free chart.

Topic:

Climate Change

LT focus:

  • Become aware of the need to reduce waste and reuse and recycle material
  • Say what the 3 Rs are.

Introduction

Whole Class Discussion: Ask the class if they have ever heard the term the “3Rs”?

Show video-See additional info. After, ask them what the 3 Rs mean?

Write on board-the 3Rs refers to three terms often used when talking about waste: Reduce, Reuse, and Recycle.

Reducing is cutting back on the amount of trash we make, reusing is finding a new way to use trash so that we don’t have to throw it out, and recycling is using trash to remake new goods that can be sold again

Development

This is a link with Science.  Ask permission to dig hole in school grounds!

Cut the four bags so that they’re all the same height. Teacher will do most of the manual work.

  1. Place identical solid waste ingredients into each bag, and secure the bags with twisty ties.
  2. Place the bags side by side in the trench, then cover with dirt so that just the tops of the bags are showing.
  3. Evenly water the soil over the bags.
  4. Cover the trench with the boards, and weight them with some stones or bricks. This will help to keep any critters who smell the trash from digging up your experiment.
  5. Wait for four weeks and uncover the bags. Remove enough dirt so that you can observe the bags, and record your observations. Remember to use your sense of smell, and be sure to wear rubber or latex gloves when handling the rubbish.
  6. Replace the dirt over the bags, and put the wood back over top of the trench.
  7. Four weeks later, uncover and dig up the bags again, making sure to note your observations.
  8. Dispose properly of all rubbish, and fill in the trench so it’s level with the ground around it.

Plenary

Children can write a report up outlining what they discovered
