Year 8 - The Moving Picture Project

A book company intends to develop a child's animated book. You have been asked to make a moving picture of a clown's face to use in the book.
Once you have made the moving face which will be operated by hand you may incorporate electronic components e.g. reed switches and L.E.D'S to make flashing eyes.

Limitations

The card model / Prototype.

1. The face of the clown will be made from strong card.
2. The face will be accurately drawn with colours applied.
3. The ears or hair of the clown will be moved by the use of linkages.
4. The linkages will be made from lollipop sticks and paper fasteners.

The face made in Resistant Materials

1. The face will be re-made in M.D.F.
2. The linkages will again be made using lollipop sticks.
3. The ears or hair will be made in card.
4. Electronic components will be incorporated. When the pull stick is pulled the ears or hair will move and the eyes will light up.
5. The components to be used are L.E.D'S, a Reed switch, a Resistor, a Magnet and a 9volt Battery.

Requirements

· Initial ideas for the clown's face.
· A working cardboard model.
· A working M.D.F face with electronic components built in.
· A diary of practical work.
· A parts list of all materials and a list of electronic components.

You will learn the following;

· To make basic mechanisms - linkages, levers.
· To understand input, output, fixed pivots, moving pivots.
· To use electronic components.
· To be able to model in card.
· To understand other mechanisms - Pulleys, Gear Systems, Bell Cranks and Sliders, Ratchet and Pawls, Rack and Pinions.
· To make a moving children's toy out of resistant materials.
· To learn soldering techniques.

Extension work

· Research, sketch, and label mechanisms

Year 8 - Moving Picture

The Task

To make a moving picture / face children's toy. The face will be hand operated and will contain linkages. The extension face will incorporate flashing L.E.D's, Reed switches, Magnets and a Resistor.

Setting The Task

Many moving items that are man-made either incorporate or are operated using mechanisms.

Main Aims

1. To understand basic mechanisms - Levers, Linkages and to appreciate input, output, fixed pivots and moving pivots.
2. To understand electronic components - Reed switch, Resistors, L.E.D's and to learn what they do.
3. To be able to model with card linkages.
4. To understand other mechanisms in the context of the school environment - Pulleys, Gear Systems, Bell Cranks and Sliders, Ratchet and Pawls, Rack and Pinions.
5. Ideally to use model kits to build mechanisms and to access a C.D Rom system on mechanisms.

Values

Technical

· To acquire knowledge of mechanisms in society in general and in the school workshop machinery.
· To acquire knowledge of electronic components and to use them in projects.
· To design and develop a product for a particular market.

Environment

· To understand how mechanisms are used in the workshop and the safety aspects involved in a machine.

Society
· How life is made easier for us because of mechanisms.

The Nature Of The Product

· To make basic mechanisms - Levers, Linkages and to appreciate input, output, fixed pivots and moving pivots.
· To incorporate electronic components into a project - Reed switch, Resistors, L.E.D's and to learn what they do.
· To be able to model with card linkages.
· To understand other mechanisms in the context of the school environment - Pulleys, Gear Systems, Bell Cranks and Sliders, Ratchet and Pawls, Rack and Pinions.
· To make moving children's toy.
· To learn soldering skills.
