hazardous
dangerous

1. Discover: The sorting bins

At school there are three bins: one for food scraps, one for paper and one for plastic and cans. Hadiza puts a peel in the first and her paper in the second. “We are sorting,” she says. “The peels become compost for the garden.”

Think: Why are there different bins?

2. Understand: Where waste goes

Idea 1: Right bin, right waste

We dispose of waste in bins, not on the ground. Different bins help us sort: food scraps, paper, plastic and metal, and glass.

Idea 2: Compost and recycle

Food scraps and leaves can be made into compost, which feeds the soil and helps plants grow. Paper, plastic, glass and metal can be recycled into new things.

Idea 3: Dangerous waste

Some waste is hazardous, such as broken glass, needles, batteries and chemicals. Children never touch it. They tell an adult, who handles it safely.

Remember: We put waste in the right bin, compost and recycle, and leave dangerous waste to adults.

3. Worked examples

Example 1 (I show you): Which bin?

A banana peel.

  1. It is organic.
  2. It can be compost.
  3. Food bin.

Answer: A banana peel goes in the food or compost bin.

Example 2 (We do it together): Recycle?

A drink can.

  1. It is metal.
  2. Can be recycled.
  3. Metal bin.

Answer: A drink can goes in the metal recycling bin.

Example 3 (You try): Broken glass

You see it.

Show the steps and answer
  1. Do not touch.
  2. Tell an adult.
  3. An adult cleans it.

Answer: Tell an adult about broken glass.

Did you know?

Recycling one aluminium can saves enough energy to run a television for several hours.

Why this matters

Proper disposal keeps places clean, protects animals and saves materials.

4. Explore: Bin game

Sort pretend waste into labelled boxes.

  1. Label boxes: food, paper, plastic, metal.
  2. Use pictures or clean items.
  3. Sort each item.
  4. Check with a friend.
Think about it: what did you notice?

What did you notice? Sorting is easy when bins are labelled.

Safety first: Use clean items or pictures. Do not touch real rubbish with bare hands. Never touch sharp or hazardous waste. Wash hands after the activity.

Mastery and remediation

Objective Bronze (Developing) Silver (Proficient) Gold (Advanced)
O1 Say where each kind of waste goes Shows this with help from an adult or a picture Does this independently and explains how they know Explains it clearly and uses it in a new situation
O2 Sort waste into bins Shows this with help from an adult or a picture Does this independently and explains how they know Explains it clearly and uses it in a new situation
O3 Say why we reuse and recycle Shows this with help from an adult or a picture Does this independently and explains how they know Explains it clearly and uses it in a new situation

Courseversity badge thresholds (overall quiz score): Gold = 90–100%; Silver = 80–89.9%; Bronze = 70–79.9%. A badge is never a full record of progress.

If a learner struggles

  1. Find the misconception: “All waste goes in the same bin.” Sort for recycling.
  2. Explain another way: use real objects, pictures or actions first, then words.
  3. Show a simpler example: Use pictures. Sort into four bins.
  4. Guided practice: work through one example together and let the learner try the next one.
  5. Reassess: use the quiz again or the worksheet.
  6. Move on when the learner shows Silver-level evidence independently.

For parents and guardians

In this lesson your child learns how to dispose of waste properly. You do not need to be an expert to help.

  • Sort waste at home.
  • Ask, “Which bin?”
  • Never touch sharp rubbish.
  • Ask “how do you know?” after each answer, and listen.
  • Praise effort, not only right answers. Mistakes are how we learn.
  • Ten to fifteen minutes a day is better than one long session.

Teacher package

1–5. Objectives, prerequisites, materials, preparation, duration

Lesson objectives. Learners will: say where each kind of waste goes; sort waste into bins; say why we reuse and recycle; say what to do with dangerous waste.

Prerequisite knowledge. None. Learners should be able to look, listen and talk about what they notice.

Materials. Boxes labelled food, paper, plastic, metal; clean pictures; chart paper. Low-resource options: use chalk or charcoal on a board or wall, drawings in the sand, and objects from the classroom instead of printed materials.

Preparation. Prepare boxes. Use only clean items or pictures. Plan the sorting game.

Suggested duration. 45–60 minutes. It can be split into two shorter sessions.

6–9. Teaching procedure, explanation notes, guided and independent activities

Introduction (5 min). Ask, “Where does this go?”

Explanation (10 min). Teach disposal and recycling.

Guided activity (10 min). Learners sort pictures.

Independent activity (10 min). Learners plan a bin system.

Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.

Key questions. Which bin? Is it safe?

Teacher explanation notes. Start with real objects and safe, hands-on observation. Then talk about what was seen, then draw and write. Always say “how do you know?”. Keep to the safety notes, and use local, safe materials.

10–12. Differentiation, formative assessment, common misconceptions

Support. Use real objects and pictures, short sentences and a partner. Let learners point, show or draw instead of writing. Extension. Ask learners to find a new example at home and explain how they know.

Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.

Misconceptions. “All waste goes in the same bin.” Sort for recycling.

13–15. Assessment questions, answer keys, marking scheme

Use the quiz, the 10-mark exam practice and the worksheet on this page. All answers and marking guides are in the answer sections above. Re-check every answer before use.

16–19. Remediation, enrichment, homework, teacher reflection

Remediation. Use pictures. Sort into four bins. Enrichment. Look for one new example near your home or school, draw it and explain it to someone. Homework. See above.

Teacher reflection. After teaching, record: which ideas learners understood; which misconceptions occurred; which activities worked; which learners need more practice; and what to improve next time.
