Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.
These resources were created for remote use during the pandemic and are not designed for classroom teaching.
Lesson details
Key learning points
- Metals are good thermal and electrical conductors, they are strong, shiny, malleable and ductile.
- Non-metals are normally poor thermal and electrical conductors, they are not strong, and are dull and brittle.
- Graphite is a non-metal that is a good electrical and thermal conductor.
- Metals are found on the left side and in the middle of the periodic table, non-metals on the right side.
Keywords
Thermal conductor - A thermal conductor is a substance that transfers heat from one place to another place.
Electrical conductor - An electrical conductor is a substance that allows a flow of charge (electrical current).
Malleable - A malleable substance has the ability to be formed into a shape.
Brittle - A brittle substance has the ability to break up easily.
Ductile - A ductile substance has the ability to be pulled into a wire.
Common misconception
There are exceptions for both metals and non-metals, which have different properties.
Use examples such as mercury and graphite in your teaching.

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.
