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
- Materials for manufacture are chosen based on performance, cost, and sustainability.
- Physical and working properties like strength, flexibility, and durability determine how well a material performs.
- Manufacturers must balance trade-offs between performance, cost, and sustainability when selecting materials.
- In a school workshop, cost is often the most critical factor when selecting materials.
Keywords
Performance - how well a material does its job and meets the needs of the product
Cost - the price of buying, processing and using a material
Sustainability - a product or material that has minimal environmental impact through its reuse or replenishment
Properties - the characteristics of a material (like hardness, weight, or conductivity) that determine how it looks, feels and behaves when used
Common misconception
The cheapest material is always the best choice.
Material selection involves balancing multiple factors, such as strength, durability, weight, sustainability, and ease of manufacturing; in addition to cost.

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.
