Unit outcomes

Pupils who are secure will be able to:

  • Describe what a shell structure is and describe what makes an effective helmet.
  • Design a helmet for a specific user by choosing appropriate features.
  • Explain layering techniques used to strengthen a helmet.
  • Use layering techniques to make a helmet and reflect on the process.
  • Evaluate the strengthening required in the helmet and justify appropriate strengthening techniques.
  • Follow a design plan and use appropriate techniques to strengthen and stiffen the helmet.
  • Communicate with peers when making improvements.
  • Analyse helmets’ strengths and weaknesses and evaluate how they work for their purpose.

Three pre-made papier-mâché helmets are required for Lesson 3: Strengthening techniques. Watch the Pupil video: Papier-mâché helmets and follow the steps to create shell structures showing one, two and three layers of papier-mâché to compare during the lesson.
