*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:
- Create and annotate design plans for a shell structure, identifying shape, material and purpose.
- Explore different shell structures, analyse user needs and make a design plan.
- Use tools to shape and assemble parts of a shell structure.
- Use layering techniques to strengthen a shell structure.
- Choose from materials to best strengthen and stabilise shell structures.
- Evaluate shell structures after testing, considering peer feedback and making improvements.
- Explain how a shell structure can be strengthened and stiffened.
Three pre-made papier-mâché helmets are required for Lesson 3: Strengthening techniques. Watch the Pupil video: Making a shell structure and follow the steps to create shell structures showing one, two and three layers of papier-mâché to compare during the lesson.
