Sources and stock forms of polymers
Lesson details
Learning outcome
I can describe where different materials come from and identify their common stock forms.
Key learning points
- Raw materials need to be sourced and processed into a useable form.
- Materials are available in a range of stock forms, which influences material selection and production methods.
Keywords
Source - where a material originates from
Raw material - a natural material in its original state
Process - changing a material to make it suitable for making products
Stock form - the standard shape or size a material is supplied in
Common misconception
All materials are ready to use in their natural state.
Raw materials need to go through a range of processing stages to make them usable.
Teacher tip
Use real-life samples of raw and processed materials to reinforce the idea that materials go through significant changes before becoming stock forms.

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.
