National Curriculum Links

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

KS1

• Science (Working Scientifically):

  • Use simple measurements and begin to estimate (Year 1 & 2).
  • Recognise the importance of measuring accurately in everyday activities.

• Mathematics:

  • Recognise and use standard units of measure (Year 1 & 2).
  • Begin to understand volume and capacity (Year 1).

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

  • Understand practical life skills that contribute to self-care and independence.

KS2

• Science (Working Scientifically):

  • Take measurements, using a range of scientific equipment, with increasing accuracy and precision (Year 3 & 4).

• Mathematics:

  • Solve problems involving measurement (Year 3 & 4).
  • Use standard units (ml, litres) for measuring liquids.

• PSHE:

  • Develop independence through practical life skills.
  • Awareness of safety and hygiene when handling products.

Learning Objectives

By the end of this lesson:

• KS1:

  • Understand why it is important to measure detergent and fabric softener correctly.
  • Practise measuring liquids using visual aids and simple measuring tools (e.g., caps, spoons).
  • Recognise differences in amounts needed for small and large loads.

• KS2:

  • Accurately measure detergent and fabric softener using graduated measuring cups and spoons.
  • Calculate required amounts for varying laundry loads using multiplication/division.
  • Explain the consequences of using too much or too little detergent and softener.
  • Discuss safety and environmental impacts of laundry products.

---

Resources Needed

• Plastic detergent and fabric softener bottles or empty labelled bottles for role-play
• Measuring jugs/cups with clear ml markings
• Small plastic cups/spoons for KS1 measuring
• Worksheets with laundry load size problems (KS2)
• Posters showing correct amounts for different load sizes
• Clean fabric swatches for practical experiment (optional)
• Visual aids: pictorial instructions, dosage charts
• Aprons and gloves for safety demo
• Plastic basins for ‘pretend wash cycles’

Lesson Structure

1. Introduction (10 mins)

Activity:

• Begin by asking children about their experience with laundry or washing clothes at home.
• Show the detergent and fabric softener bottles.
• Discuss why measuring the right amount makes a difference (cleanliness, fabric care, environment).
• For KS2, introduce the concept of “load size” and how it affects measurement.

---

2. Demonstration / Modelling (10 mins)

Activity:

• Teacher demonstrates measuring detergent and fabric softener using the jugs and spoons.
• Use visual measuring cards showing small, medium, large loads and corresponding amounts in ml or caps.
• Explain the consequences of incorrect measuring (e.g., detergent residues, fabric damage, pollution).

Differentiation:

• KS1: Emphasis on ‘full cap’ vs ‘half cap’ visually.
• KS2: Include measurements in ml; clear relation to maths units.

3. Hands-on Practice (20 mins)

Split into two groups by age band for targeted activities:

• KS1 Activity:

  • Children will use small plastic cups/spoons to measure detergent and softener.
  • Practice ‘pouring’ correct amounts into pretend washing machines (basins).
  • Teachers use pictorial sheet showing amounts for each load size.
  • Talk through measuring vocab: full, half, less, more.

• KS2 Activity:

  • Hands-on measuring of detergent and fabric softener into jugs.
  • Complete worksheet problems where children calculate detergent needed for 2x or ½ loads.
  • Encourage peer discussion on how to measure precisely and safely.

4. Group Discussion and Reflection (10 mins)

Activity:

• Come back together to discuss what they learned.
• KS2 students can present their problem-solving results.
• Cover safety: why don’t we drink or spill these liquids? Why wash hands after use?
• Reflect on personal experiences – ask: How might you use these skills at home?

5. Assessment and Plenary (10 mins)

Formative assessment:

• Observe participation and measuring accuracy during hands-on activity.
• Use simple Q&A to check understanding: “What happens if you use too much detergent?”
• Collect KS2 worksheets for review of calculations.

Plenary:

• Quick ‘True or False’ game with statements about measuring detergent/softener correctly and laundry facts.
• Praise their skills and preview next lesson (sorting laundry by fabric type).

---

Extension Ideas (for early finishers or homework)

• Design your own detergent label showing measuring instructions and safety tips.
• Create a rhyme or song to remember how much detergent to use for different loads.
• At home, practise measuring detergent with an adult and report back what you learned.

---

Safety Considerations

• Ensure all products used are empty or safe for handling.
• Emphasise hygiene and hand washing after handling detergent/softener.
• Supervise use of measuring equipment carefully to avoid spills.

---

Reflection Notes for Teacher

• Are students able to demonstrate accurate measuring skills?
• Did KS2 students apply multiplication/division in measurement calculations correctly?
• Did students understand environmental and safety issues related to laundry products?
• Adapt future lessons based on need for more practical measuring or safety awareness.

This lesson integrates practical life skills with core Science and Maths objectives from the National Curriculum, fostering independence and responsibility from an early age. The multi-sensory approach and differentiation ensure engagement and accessibility for all KS1 and KS2 learners.
