PSLE Science 2012 Question — Birds vs Mammals Differences Explained

Source: PSLE Science 2012 Q2

Introduction

How do we tell birds and mammals apart in PSLE Science questions? 🤔
Understanding PSLE Science birds and mammals differences is a common exam topic and often appears in MCQs.

This 2012 PSLE question tests classification skills — a key area in Primary Science.

Let’s break it down clearly.

 

The Question

Which characteristic can be used to differentiate between birds and mammals?

Options:

  1. Number of legs
  2. Body temperature
  3. Presence of wings
  4. Type of body covering

 

Step-By-Step Explanation

We analyze each option carefully.

❌ Number of Legs

Both birds and mammals can have four limbs.

Example:

  • Birds → 2 legs + 2 wings
  • Mammals → 4 legs

So this does NOT clearly differentiate them.

❌ Body Temperature

Both birds and mammals are warm-blooded.

So this is NOT a difference.

❌ Presence of Wings

Some mammals (like bats) also have wings.

So this is NOT reliable.

✅ Type of Body Covering

✔ Birds have feathers
✔ Mammals have fur or hair

This is a clear difference.

 

✔ Correct Answer:

Option (4) Type of body covering
