Lesson details
Key learning points
- Polymers are very large covalent molecules (not giant structures)
- Polymers can be represented by showing repeated units
- Polymers consist of repeating and identical sections called monomers
- Polymers are solid at room temperature because the intermolecular forces between polymer molecules are relatively strong
Keywords
Polymer - Polymers are long-chained molecules formed by joining together monomers.
Monomer - Monomers are small molecules that can join together to form a polymer.
Repeating unit - The section of a polymer that repeats is known as the repeating unit.
Intermolecular forces - Intermolecular forces are weak forces of attraction between molecules, and molecular substances.
Common misconception
Not including the bonds either side of the repeating unit.
The slide deck states the need for open bonds to show how repeating units are bonded to each other.

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.
