Yr:6 Plans: Design and TechnologyControllableVehicles
(Differentiatedactivities will be prepared on a daily basis)
Tellthe children that over the next term, they will be designing andmaking a controllable toy vehicle. Discuss what is meant by theterm controllable and toy. From these definitions children drawup design specification thinking about the potential user andpurpose.
Ask children tobring in toy cars from home in order to help us to research ourideas.
Children investigatetoy cars, identifying the key parts of the toy. What makes it move?How can I control it? What does it look like?
Children makedetailed labeled diagrams of the toy cars to show how they aremade. Children then think about their own car. What do they want itto look like? How will they make it? What materials will they use?Emphasise that this is not a final design but a series of potentialdesign ideas.
Show the childrenthe basic chassis that they could use. Demonstrate how this is madefrom wood and strengthened by cardboard corners. Detail to thechildren how this is made and the tools that are used. Demonstratethe skills that are needed through the production of a rectangularphoto frame. Children to follow the instruction of the teacher stepby step ensuring that they listen careful to the safetyinstructions that are part of the explanation. Discuss the need forsafety instructions.
Demonstrate howaxels and wheels are added to the chassis. Talk children throughhow this is done using the frame from last week. Complete the basicchassis and show children how this works as a vehicle. Visitwebsite http://ngfl.northumberland.gov.uk/dt/workshop/projects/project3/P3vehicle-intro.htm show thechildren the design template which incorporates a steeringmechanism. Children then create their own design for the chassisincorporating the two designs or replicating one of thedesigns.
Show the childrenthe circuit diagram for the motor. Ask children how this could bemade and what would happen. Demonstrate how this could be placed inthe car Discuss how a switch could be incorporated and why thismight be useful. Tell children that this could be used in ourvehicle. Discuss other components that could be used e.g. LED,buzzer etc. Children then to design their own circuit to beincluded in their vehicle. Children to price the components andcomplete their budget sheet.
Discuss theimportance of appearance. Children investigate how their car couldbe given a body in order to ensure that it is appealing to theuser. Show the children the 3 net designs from www.nuffielddesign.co.uk.Children to print out a net design for their car and adapt it sothat it fits their chassis. Teacher to demonstrate the need forcareful cutting, scoring and gluing. Children to copydemonstration. Discuss decoration techniques that could be usede.g. adding a different texture, foil, transparent film etc.Children to experiment with designs.
Children to completea final design for their proposed toy. Children to ensure thattheir plan details the chassis, body and mechanism through labeleddrawings/explanations. Children to provide an equipment list andseries of instructions for how they will make the car.
Children to buildtheir car using the techniques that have been researched in class.Children to create the chassis, boy and mechanism for theircar.
