Lesson details
Key learning points
- Metals are good thermal and electrical conductors, they are strong, shiny, malleable and ductile.
- Ceramics are made from soft substances, becoming hard and brittle when heated.
- Plastics are made from polymers and there are many types of plastics with very different properties.
- An alloy is a mixture of elements including at least one metal.
- Composites combine materials to create a new material with improved properties.
Keywords
Metal - A material that is shiny, hard and a good thermal and electrical conductor.
Ceramic - A material which is hard and brittle.
Polymer - Long chained molecules formed by joining together monomers.
Alloy - A mixture of two or more elements where at least one element is a metal.
Composite - A material made from two or more different types of materials. When combined they create a new material with improved properties.
Common misconception
The word material can be challenging, it has a different meaning in everyday life. Understanding that an alloy is a mixture and not a compound is hard because the elements are difficult to separate.
Provide lots of different examples of materials and use the word correctly within the scientific contexts. An alloy is the exception to the rule and is separated by thermal or chemical processes.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
