Forces and stresses

Changing material properties through manipulation, reinforcing and stiffening



This dynamic unit fuses mathematical content with physics based solutions to create a series of predominately practical investigations that deliver theory in a fun and interactive way. It encourages problem solving and teamwork as well as planning and budgeting. The lessons work through basic stresses and forces before looking at solutions through the manipulation of materials. A team challenge is set which leads to destructive testing in a competitive environment.

What's included

The currently available units have been written to satisfy the new National Curriculum for Design and Technology. They are designed for teaching at KS3 but individual lessons in some units may also be appropriate for teaching Key Stages 2 or 4, particularly where Year 10 students may not previously have been exposed to certain topics.

  • PowerPoint slides for each lesson
  • Detailed lesson plans
  • Learning objectives and outcomes
  • Statement of which of the Government Guidelines are covered in the unit
  • Worksheets and activities
  • End-of-unit Assessment material
  • Other material and links to online resources

What people say...

Our pupils really enjoy the range of relevant topics, as well as the mixture of activities in each lesson. Needless to say, but we shan’t look anywhere else when it comes to resourcing the teaching of our future KS5 courses.

Many thanks for providing excellent detailed resources which will help my team endlessly!
