PSLE Science P3 Question 2 – Materials for Raincoat Explained

Source: PSLE Science Primary 3 Question 2 – Materials

Introduction

Why is plastic suitable for making a raincoat?
This PSLE Science Materials Raincoat Question tests students on understanding material properties and choosing the correct characteristics based on daily-life applications.

In this blog, we walk through the exact teacher explanation to help Primary 3 students answer this question confidently in exams.

 

The Question

The diagram below shows a raincoat.

Plastic is a suitable material for making a raincoat because it is ______.

Options given:

  • (A) fragile
  • (B) flexible
  • (C) waterproof
  • (D) absorbent

Which option is correct?

 

Step-by-Step Explanation

Let’s analyse each property carefully using PSLE Science concepts:

❌ Fragile

  • Fragile means easily broken.
  • A raincoat must be durable, not fragile.
    ➡️ Eliminate (A)

✅ Flexible

  • A raincoat must bend and move with the body.
  • Plastic allows easy movement.
    ➡️ Keep (B)

✅ Waterproof

  • A raincoat must prevent water from passing through.
  • Plastic does not allow water to seep in.
    ➡️ Keep (C)

❌ Absorbent

  • Absorbent materials soak up water.
  • Raincoats must repel water, not absorb it.
    ➡️ Eliminate (D)

 

Final Answer

✔ Option (3): B and C

Plastic is flexible and waterproof, making it suitable for a raincoat.

 

Key Concepts

ConceptExplanation
WaterproofPrevents water from passing through
FlexibleCan bend without breaking
AbsorbentSoaks up water (not suitable)
FragileBreaks easily (not suitable)

 

Common Mistakes

❌ Choosing “absorbent” because students confuse raincoats with towels
❌ Thinking “fragile” applies to thin plastic
❌ Selecting only one correct property instead of two

 

Tips for Students

✔ Think about real-life use
✔ Ask: “Does this material allow water in?”
✔ Always eliminate opposites (absorbent vs waterproof)
✔ Look for two correct properties, not just one
