Section A: Multiple Choice (12 marks)

1. Which material is transparent? (2 marks) Answer: 2. Glass Glass is transparent, meaning you can see through it clearly. Wood, metal, and paper are opaque.

2. A material that can bend easily without breaking is called: (2 marks) Answer: 3. Flexible Flexible materials can bend without breaking. Hard/soft refers to how easily they can be pressed, waterproof refers to water resistance.

3. Which material is best for making an umbrella? (2 marks) Answer: 3. Plastic (because it's waterproof) Plastic is waterproof and will keep rain out. Paper gets wet, cloth absorbs water, metal is too heavy and conducts heat.

4. Natural materials come from: (2 marks) Answer: 2. Nature (animals, plants, earth) Natural materials come from living things or the earth. Man-made materials come from factories and laboratories.

5. Which of these is a man-made material? (2 marks) Answer: 3. Plastic Plastic is synthetic and made in factories. Cotton, wood, and wool all come from nature.

6. A sponge is good for cleaning because it is: (2 marks) Answer: 2. Soft and absorbent Sponges can absorb water and are soft so they won't scratch surfaces. They're not hard, transparent, or rigid.

Section B: Short Answer (14 marks)

7. Name TWO properties that make glass suitable for windows. (2 marks)

a) Transparent (1 mark) b) Hard/Strong/Durable (1 mark)

Glass lets light through and is strong enough to protect from wind and rain.

8. Sort these materials into natural and man-made: (2 marks) [Cotton, Plastic, Wood, Glass, Wool, Paper]

Natural: Cotton, Wood, Wool (1 mark) Man-made: Plastic, Glass, Paper (1 mark)

Natural materials come from living things; man-made materials are processed or synthetic.

9. Why is rubber a good material for making car tires? (2 marks)

Answer: Rubber is flexible, waterproof, and durable. It can grip the road and withstand wear.

Rubber's flexibility helps it grip different surfaces, while its durability means it lasts long.

10. Look at this table. Complete the missing properties: (2 marks)

Material	Hard/Soft	Waterproof?
Metal	Hard	Yes
Sponge	Soft	No

11. Which material would you choose to make a water bottle? Explain why. (2 marks)

Material: Plastic Reason: Waterproof, lightweight, durable

Plastic won't leak, is easy to carry, and won't break easily like glass.

12. Name ONE natural material and ONE man-made material used to make clothes. (2 marks)

Natural: Cotton/Wool/Silk (1 mark) Man-made: Nylon/Polyester/Acrylic (1 mark)

13. Mei Ling wants to make a bag that won't let water in. What property should the material have? (2 marks)

Answer: Waterproof

Waterproof materials don't let water pass through them.

Key Learning Points:

Material Properties:

• Transparent: Can see through (glass, clear plastic)
• Opaque: Cannot see through (wood, metal, paper)
• Flexible: Can bend without breaking (rubber, fabric)
• Rigid: Cannot bend easily (metal, glass)
• Waterproof: Water cannot pass through (plastic, metal)
• Absorbent: Soaks up water (sponge, paper, cotton)
• Hard: Difficult to press or scratch (metal, glass, wood)
• Soft: Easy to press or compress (sponge, cotton, foam)

Material Sources:

• Natural: From nature (wood, cotton, wool, rubber from trees, leather)
• Man-made/Synthetic: Made by people (plastic, glass, nylon, paper)

Choosing Materials:

• Match the material's properties to what you need
• Consider multiple properties together
• Think about safety and practicality
