Your assignment is to build a vehicle from at least partly recycled materials (eg. wood off-cuts, cardboard toilet rolls, boxes, bottle lids, CD's, etc). You will investigate, design and produce a vehicle that will travel at least 1 metre with the following restrictions: Its energy storage device can only be a balloon or a large rubber band No commercially available wheels are to be used It must travel on the floor - wood/concrete/lino It must begin from a standing start - no pushing The energy storage device must travel with the vehicle You need to complete a detailed diagram of your design, including measurements, a list of all materials used and a how to guide. You will also have to prepare a list of design goals that you will use to assess your completed machine.

Your Self Propelled Vehicle design will be judged on: Originality and Aesthetics 25% Technical Design and How well it functions 25% Sketches and Diagrams 25% Final presentation 25% Your finished product will be presented to the class in the last week of term 2. Good Luck!

Investigate and design What information do you need to develop your design? Make a list of questions you need to research. Use simple mind maps, sketches and labelled diagrams to explore different design solutions. Develop three rough designs for your vehicle. Remember your designs must include some of the simple machines we’ve looked at this term. Label them as Design idea 1, Design idea 2, Design idea 3. Then the key parts of each design. Choose one design solution. Record: Which number design have you chosen? and Why did you choose this design? Draw a more detailed plan and make a list of materials required and why you chose that material. Don’t forget to list joining materials (glues etc) too. Record a list of design goals that’ll you use to evaluate your completed product.

Produce Using your plan and list of materials construct your product. Write a step-by-step plan of how you make your vehicle including the tools and equipment that you will use. Make ongoing modifications to your design and develop alternative solutions to fix any problems in your design.

Analysis and Evaluate Present your finished product to the rest of the class. Explain its various features and why you have included them into your design. Explain the difficulties or problems that you had and how you worked to overcome them. Evaluate your completed product using your list of design goals.

Final Reflection Draw a picture of your finished vehicle (paste it on this page).

Final Reflection Compare the drawing of your finished vehicle with your first drawing. List the things that are different.Do you think the changes you made to your vehicle made it better? Why?

Final Reflection Look back at the materials you said you would use. Did you use the same materials? Why/why not? Do you think the materials you used were good materials to use? Why/why not? Are there changes you could now make to your vehicle that would make it better?
