These resources will be removed by end of Summer Term 2025.
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
- Combining materials creates improved properties, compared to the individual materials alone.
- Material properties can be modified with the use of heat and/or additives.
- Reinforcing techniques can improve material performance.
Keywords
Properties - words used to describe how a material appears (physical/characteristic) or behaves when worked (working/mechanical)
Combine - to join two or more things to create something new
Modify - to change something to make it perform differently
Reinforce - to make something stronger
Structural integrity - how well something stays together and holds up without breaking
Common misconception
A material's properties are fixed and cannot be changed.
Many materials can be altered after they are made to improve their properties, e.g. strength.

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.
