Biscuit Cutter Project |
Objectives This project will give pupils the opportunity to work with MDF to produce a pattern which can be used with a vacuum forming machine and styrene sheet to produce both the cutter and by working in groups the tray or insert for the biscuit box.

Main Key Experiences & Essential Outcomes
Children will be taught :- • About symbols that could be used for spring. • How to mark out the material. • How to shape MDF to produce a suitable pattern based on a spring symbol or shape. • How to work with styrene sheet and about thermoplastics (CF thermosetting plastics). • How to use the vacuum forming machine safely. • To work in groups for certain parts of the project for mutual benefit. Children will be able to:-• Produce a paper template and then use it to mark out the final pattern. • To cut out the MDF carefully including the draft allowing ease of removal following molding. • Work safely using a range of tools, especially coping saw, sanding machine, abrasive papers (rubbing board). • Finish the work using appropriate abrasives to achieve an effective pattern, realise the need for a handle on the cutter and add one. • Work with the styrene sheet by vacuum forming followed by careful trimming, • Finally use the biscuit cutter and then fit all the parts together to present a complete biscuit package. • Add to their design folder showing the stages in the design process which led to the biscuit cutter production- brief, initial ideas including symbols for spring and biscuit shapes, final design drawing, the paper template, as well as the actual artifact . Children will begin to understand: • The importance of working accurately if the biscuit cutter is to be effective as well as attractive. • The difference between a thermoplastic such as styrene and a thermosetting plastic such as Bakelite. • How the vacuum forming machine works (very simply), and how to use it safely. • The importance of working safely especially when working with sharp tools and machines - the danger of dust when using MDF. • How to produce an effective pattern for use on the vacuum forming machine.
