Duration: 45 minutes
Class size: 1 student
Unit: Waste Wise: Sustainability in Action (Lesson 5 of 6)

---

National Curriculum Links

This lesson supports the following elements of the National Curriculum for England:

Science:

• Working scientifically (Year 5): Pupils should be taught to use test results to make predictions to set up further comparative tests.
• Materials and their properties: Understand changes that can occur in materials, including those caused by human activity.

PSHE (Personal, Social, Health and Economic Education):

• Living in the wider world: Understanding risks and how to manage them safely.

Geography/Environmental Education (cross-curricular links):

• Understanding human impact on the environment and sustainability.

---

Learning Objectives

By the end of this lesson, the student will be able to:

1. Identify what hazardous waste is and list common examples.
2. Explain the potential risks hazardous waste poses to humans and the environment.
3. Describe at least two hazardous waste management strategies.
4. Analyse a hazardous waste incident through a case study.

---

Success Criteria

• I can define hazardous waste and give examples.
• I can explain why hazardous waste is dangerous to people and nature.
• I can describe how hazardous waste should be managed safely.
• I can discuss what went wrong in a real incident involving hazardous waste.

---

Resources Needed

• Video clips on hazardous waste and its management (short and visual)
• Case study printout (simple text with images) of a hazardous waste incident (e.g., chemical spill)
• Glossary of key terms (with clear, dyslexia-friendly font and definitions)
• Paper, coloured pencils or markers
• Safety poster template for extension activity

---

Vocabulary / Glossary (Dyslexia-Friendly)

1. Hazardous waste – Waste that can be harmful to people, animals, or the environment.
2. Toxic – Poisonous or harmful.
3. Chemical spill – When dangerous chemicals accidentally leak or spill into the environment.
4. Recycle – To turn old waste into new materials.
5. Disposal – Getting rid of waste safely.
6. Containment – Stopping waste from spreading or leaking.

Lesson Structure

1. Introduction (5 minutes)

• Discuss what the student already knows about waste. Explain that today they will learn about a special kind of waste called hazardous waste, which needs very careful handling.
• Show key vocabulary and go through glossary briefly together.

2. Video Viewing + Discussion (10 minutes)

• Show a short, engaging video on hazardous waste and how it is managed (e.g., waste safely stored, cleaned up carefully).
• After video, ask:
  • What types of hazardous waste did you see?
  • Why is it important to handle these wastes carefully?
• Scaffold explanation with simple visuals and encourage the student to explain back what they understand.

3. Case Study Analysis (15 minutes)

• Present a simple case study of a hazardous waste incident (e.g., a chemical spill at a factory). Include images and captions to aid comprehension.
• Ask guiding questions:
  • What happened?
  • What risks did this incident cause? (Think about people, animals, water, land)
  • How was it cleaned up or managed?
• Help the student map the sequence of events with a simple timeline or cause-effect diagram.

4. Safety Poster Creation (Extension Activity, 10 minutes)

• Invite the student to create a safety poster that shows top tips for handling hazardous waste safely.
• Encourage use of bright colours and clear, simple messages like “Wear gloves,” “Don’t touch chemicals,” or “Tell an adult.”
• This supports creativity and reinforces learning through a practical task.

5. Review and Final Check (5 minutes)

• Discuss what was learned: ask the student to explain hazardous waste, risks, and some safety management tactics.
• Use success criteria as a checklist: Have they met each point?
• If possible, display or keep the safety poster to revisit in following lessons as a reminder.

Differentiation Strategies

• Use simple language and visual supports (pictures, icons) alongside text.
• Break tasks into smaller chunks with plenty of prompts and pauses for thinking.
• Use the video to provide an engaging multi-sensory learning experience that supports retention.
• For the printing materials, use dyslexia-friendly fonts (e.g., OpenDyslexic or Comic Sans), spacing, and pastel backgrounds to reduce visual stress.
• Offer oral rather than written responses when appropriate.

---

Extension Activities for Further Challenge

• Research and present on another hazardous waste incident from history or current events.
• Create a 2-minute “news report” video or role-play explaining how hazardous waste is managed in their community.
• Design an infographic comparing hazardous waste management methods globally.

---

Assessment

• Formative assessment through questioning and discussion during activities.
• Use responses during case study and poster creation to assess understanding.
• Check according to success criteria at the end of the lesson.

---

Reflection Suggestions for Teacher

• Did the student confidently identify hazardous waste and risks?
• Was the video effective for engagement and understanding?
• Did the poster activity allow the student to apply knowledge creatively?
• Note any vocabulary difficulties or misconceptions for future review.

This detailed lesson plan, rooted in the National Curriculum for England, balances scientific knowledge, environmental stewardship, and practical safety awareness, all made accessible and engaging for a Year 5 learner through multimodal teaching strategies and scaffolded activities.
