Design A Screwdriver
Differentiated Tasks
Core Task
Pupils will generate and develop an idea based upon a basic screwdriver. They will have extended their knowledge through investigation work at home and in school which deals with the familiar concept of a screwdriver. During teacher evaluation of their work they will communicate their design idea using an orthographic 3rd angle projected drawing using drawing instruments. Using a box construction they will draw freehand an isometric drawing of their chosen design idea.
They will use these drawings to aid their construction and during manufacture they will add notes and further sketches and ideas about new materials, skills and processes learned.
Using a range of tools that are appropriate to the task they will add these to their portfolio and demonstrate their ability to operate certain tools and equipment. They could receive a certificate of competence of tool use at this level. If their work fails to meet the requirements at the first attempt they will modify their work in light of this failure. Attention will be paid to measuring and checking procedures as the work develops. At the end of the project they will test their work against the criteria and chosen design, completing an evaluation on what they know, understand and can do well, what was successful about their design and how the design could be improved.
Extended Task
Designed for those pupils who are demonstrating higher level skills. These pupils will naturally be guided towards more advanced tool designs. Design drawing will be formal and components will be presented as an exploded view. The 2-D drawing should show a cross section of the fixing point between the blade and the handle. They will be expected to develop the method of fixing handle to shaft and test out their idea before making through a preliminary model. Their investigation will be drawn from wider sources than home and school.
Support Tasks
Designed for those pupils with Special Learning Needs ( SEN) year 8. These pupils will be provided with a closer design brief which will place design constraints upon them. If they have difficulties with design tasks they will be asked to provide a realistic verbal suggestion which the teacher will interpret for them in graphical form. Those who wish to draw their own will be able to use paper with the box construction defined by the use of a light box or other means. As the work develops they will be encouraged to add to that initial design drawing with ideas and sketches of their own and making every effort to label these with information about their design.. If they have difficulty with manufacture they could be provided with a ready made handle into which they will receive help to fix their blade. Every effort will be made to ensure that they complete the Focused Practical Tasks. Judgements will be made to ensure that they meet the requirements of the project whilst at the same time keeping to the time management plan for the whole group
