*New* Structures: Helmets
Designing and making a helmet, using strengthening techniques to reinforce the shell structure.
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.
