Ceramics, Polymers & Composites
Describe the properties and uses of ceramics (hard, brittle, heat-resistant), polymers (flexible, lightweight, variable), and composites (combine properties of constituent materials), giving real-world examples of each

- Step 1. Define ceramic, polymer, and composite.
- Step 2. Inspect or research examples without breaking or heating them.
- Step 3. Record properties such as hardness, flexibility, density, insulation, and brittleness.
- Step 4. Match materials to a mug, raincoat, and bicycle-frame requirement and justify each.
- Quick check. Present a new material description. Success means your child classifies or narrows the category and cites relevant properties rather than appearance alone.
Worked example. Fiberglass is a composite: glass fibers add strength while a polymer resin binds them into a shaped material.
Optional challenge. Design a layered or composite product and explain what each component contributes and what trade-off remains.
What to notice. Save a photo of the classification-and-properties table, or a short note quoting one evidence-based material choice.

Ceramics are often hard and heat-resistant but brittle; polymers have long-chain molecules and varied flexibility; composites combine materials to gain useful properties.
Classify six safe household materials and select one for each of three design requirements using property evidence.

Check understanding
- Gives the key properties of ceramics, polymers, and composites with examples of each
- Explains why a composite material is used rather than a single material in a given application (e.g. carbon-fibre reinforced plastic in bikes)
- Identifies natural and synthetic polymers
- Explains why polymer properties can be tailored during manufacturing
“If your child was looking at a racing bicycle made of carbon fibre, could they explain why neither carbon nor plastic alone would work as well — and what makes the combination a composite better than either material on its own?”
