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: 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.
