Unit 1B - Playgrounds

• Children explore a range of full-size items of
  playground equipment and make their own models.
• This unit gives children opportunities to learn
  about framework structures and how to make them
  stable and able to support loads

3
Unit 1D - Homes

• This unit gives children opportunities to develop
  their understanding of structures.
• They develop and model their ideas by creating
  static models from sheet and reclaimed materials
  and using construction kits. They gain a basic
  understanding about structures and how these can
  be made stronger and more stable.

4
Unit 3A - Packaging

• Through this unit children learn about
  strengthening sheet material to make a strong
  shell structure, which can be used for a variety
  of packaging. They gain knowledge about nets and
  about how complex 3D shapes can be made by using
  a net.

5
Unit 3D - Photograph frames

• In this unit, children learn about stiffening
  materials and making stable structures through
  the context of free-standing photograph frames.
  The unit uses readily available materials and
  examples.

6
Unit 5A - Musical instruments - Update

• Children learn about the construction of a range
  of musical instruments, including those from
  different times and cultures, and how different
  sounds can be created and altered to make
  different notes.

7
Unit 6A - Shelters

• In this unit, children learn about structures.
• They learn that structures can fail when loaded,
  and the use of techniques for reinforcing and
  strengthening structures. They are shown the
  strength of tubes as a construction material and
  textiles as a suitable cover for a framework.

2 main types of structure Frames

• Frame structures
• Framework The rigid structure of an object made
  by joining short rods, girders or tubes
• Examples include gates, playground equipment,
  pylons etc.

9
Frame structures

• Frames are usually made from fairly light flimsy
  materials which have been strengthened in some
  way (folding or rolling)
• Use of triangles for rigidity rectangles are
  easy to push over

10
Parts of a frame structure

• Ties are members which are under tension. Ties
  could be made from non rigid material i.e. cable
• Struts are members which are under compression.
  Struts need to be rigid.

11
2 main types of structure Shells

• Shell structures
• An outer covering with its own essential form
• Examples include-
• Shells, boxes, balloons, tubes

12
Shell structures

• Shell structures are usually made from fairly
  thin sheet material
• The strength of the shell is generated by its
  shape i.e. how the sheet material is formed by
  folding or curving

13
Shell structures are often made from nets

Icebreaker activity 1

• Making paper stronger
• Using a single sheet of A4 paper and the
  fastenings available to you see how many
  different ways you can find to support a wooden
  wheel above the table
• Now see how many wooden wheels can be held 10cm
  above the table using a single sheet of A4

15
Icebreaker activity 2

• Now using newspaper and the fastenings available
  to you, build a tower to support a wooden wheel
  as high as possible off the floor.
• Have fun!
