Year 8 - The Display Stand Project


The Problem

· To support the display surface (a) at a minimum height of a 100mm from the table top (b).

· An adjustable pivot (c) should allow the display surface to be moved at a variety of angles.

· The supporting stand or structure should be strong enough to support the weight of the display surface.


Programmes Of Study References

2b Apply skills, knowledge and an understanding from the programmes of studies of other subjects, where appropriate, including art, mathematics and science.
3d Consider the needs and values of intended users and develop criteria for their design to guide thinking and form a basis for evaluation;
3b Use design briefs to guide design thinking;
3c Develop a specification for their product;
3f Consider the aesthetics, function, safety, reliability, and the cost of their designs;
3g Take account of the working characteristics and properties of the materials and components when deciding how and when to use them;
3l Evaluate their design ideas as these develop, bearing in mind the users and the purposes for which the product is intended, and indicate ways of improving their ideas.
4a use a range of processes to shape and form materials, including forming by wastage, attachment, adhesion and combining;
4b Select materials, tools and equipment appropriate to the task;
4c Select and use appropriate methods of shaping and forming materials accurately;
4j Evaluate their products as these develop, including testing performance against specified criteria;
4k Implement improvements they have identified and take ongoing action to ensure that their products meet the specification and their original intentions.
7a To recognise and use structures in their products;
7b That excessive loads can cause structures to fail by buckling, bending, and twisting;
7c To use simple tests to determine the effects of excessive loads;
7d To devise suitable methods to reinforce their structures and relate these and other techniques to familiar structures;
7e To understand that forces, such as compression and tension, produce different effects, and to take account of these in making their products;

Year 8 - Structures (Display Stand)

The Task

Pupils are expected to create a simple display stand. The finished item must show that they have considered support, strength and structures.

Setting The Task

Most items / constructions that are man-made have been designed with the safety of the user being the main concern. For the object to be safe it has to be structurally strong.

Main Aims

1. To understand basic structures considerations - Tension, Rigidity, and Strength.
2. To make paper structures to test and hold weights.
3. To understand Basic structures considerations - Bending, Shearing, and Triangulation.
4. To make card beams sections, test with weights, put results into a chart and draw own conclusions.
5. Draw Pub Sign; examine how to support sign with tension and compression. Make model of sign.
6. Produce Brief and Initial ideas for display stand make stand.
7. Homework's- Write up experiment results, Presentation Drawing, Cutting lists, Research woods.

Values

Technical

· To acquire knowledge of structures. Aesthetics
