Free Year 9 Properties of Materials: Metals, Polymers, Ceramics and Composites Worksheet
Students define material properties such as strength, hardness, flexibility, brittleness, thermal and electrical conductivity and melting point, then classify materials as metals, polymers, ceramics or composites. They link the properties of each group to everyday uses, analyse results from a strength test by calculating averages, and justify the choice of materials for a design.

How to use this worksheet
- Print the PDF or complete it on screen. Write the student's name and date at the top.
- Read the instructions for each part together before starting. Encourage working to be shown.
- Mark with the answer sheet. Use the model answers and success criteria as a guide rather than a single right answer.
- Record the score, celebrate what went well, then follow the "What's next" suggestion.
Common questions
Who is this worksheet for?
Year 9 students (typically ages 13–14) working on states of matter & materials. It is pitched at level 2 · standard.
Are the answers included?
Yes. The PDF includes a full answer sheet with model answers and success criteria where there is more than one good answer. You can also view the answers online.
How long does it take?
About 35 minutes for 15 questions. Short, regular sessions work best: two or three a week beats one long one.
Do I need to sign up to download?
No. Click Download Free PDF and it opens immediately. It is free for personal, classroom and homeschool use.

Always link a property to the job: say what the material must do and which property allows it.
Part A: Describing properties
The properties of a material describe how it behaves. Engineers choose materials whose properties suit the job.
Important properties include strength, hardness, flexibility, brittleness, malleability, thermal and electrical conductivity, melting point, density and whether a material is waterproof or transparent.
1.Match each property to its meaning.
- Hardness
- Flexibility
- Brittleness
- Thermal conductivity
- Malleability
- Tensile strength
- Resists being scratched or dented
- Bends without breaking
- How well heat passes through it
- Resists being pulled apart
- Can be hammered or pressed into shape
- Breaks or shatters suddenly when hit
2.A material that is hard is always strong as well. ☐ True ☐ False
3.Explain why the property of being waterproof is important for the material of a raincoat but not for the material of an oven tile. (answer space)
Part B: Groups of materials
Classify each material, then answer the questions.
Metals (iron, copper, aluminium): strong, shiny, malleable, good conductors of heat and electricity. Polymers (plastics, rubber, wool): light, flexible, usually insulators, can be moulded. Ceramics (clay, glass, porcelain): hard, heat resistant, insulators, but brittle. Composites combine two or more materials to get the best properties of each, such as reinforced concrete.

5.A plastic drink bottle

6.A porcelain plate
- AMetal
- BPolymer
- CCeramic
- DComposite
7.Reinforced concrete (concrete with steel rods inside)
- AMetal
- BPolymer
- CCeramic
- DComposite
8.Which property is shared by most metals?
- ABrittle
- BGood electrical conductor
- CLow density
- DTransparent
9.Ceramics such as clay tiles are used to line ovens and kilns. Give two properties of ceramics that make them suitable. (answer space)
10.Why are electrical cables made of copper wire covered with a polymer (plastic) coating? (answer space)
11.Ceramics are a good choice for items that will be dropped often, because they are hard. ☐ True ☐ False
Part C: Testing strength
Students tested three strings of equal length and thickness by hanging masses from them until they broke. They did three trials for each.
String A: 2.0 kg, 1.1 kg, 2.1 kg · String B: 3.2 kg, 3.4 kg, 3.0 kg · String C: 5.1 kg, 4.9 kg, 5.0 kg (mean 5.0 kg)
12.Calculate the mean mass that string B held before breaking.
