Mechanisms

Year One

that simple levers and sliding mechanisms can be used to create movement
that levers are used in products eg scissors, balances and moving books
to use drawings to represent products
that construction kits can be used to try out ideas
to make simple sliding and lever mechanisms
how to use tools eg scissors and a hole punch safely
to suggest ideas and explain what they are going to do
to model their ideas in card and paper
to make their design using appropriate techniques
to evaluate their product by discussing how well it works in relation to the purpose

Year Two

that a winding mechanism has an axle that turns and a handle
to observe carefully what happens when such a mechanism works
to make simple drawings to show how the mechanism works
techniques for making winding mechanisms
to use tools accurately and safely
to investigate and evaluate ways of making characters for the toy
to identify criteria for their design
to select tools and materials and use correct vocabulary to name and describe them
to assemble, join and combine materials to make a winding mechanism
to understand the need for a stable structure to support a mechanism
to evaluate against design criteria

Year Three

how air pressure can be used to produce and control movement
techniques for making simple pneumatic systems
to compare the effectiveness of different systems
to use appropriate vocabulary to describe how things work
how to assemble simple pneumatic systems
ways of fixing components
ways of using pneumatic systems in conjunction with simple levers to control movement
to explore ideas through 3D modelling
to work as a team
to choose an idea according to logistical constraints of materials, time, size
to think about their ideas as they make progress and be willing to change things if this helps them to improve their work
to plan through discussion
to work safely and accurately with a range of simple hand tools
to use a storyboard to record the sequence of their work
to evaluate as a team the product and purpose of improvements

Year Four

to investigate and evaluate products with lever and linkages systems, in order to learn how they function
to relate the way things work to their intended purpose
to use appropriate technical vocabulary to describe materials and mechanisms
to measure, mark out, cut and shape a range of materials, using appropriate tools, equipment and techniques
to join and combine materials and components accurately in temporary and permanent ways
how simple mechanisms can be used to produce different types of movement
how to use simple graphical communication techniques
to explore, develop and communicate aspects of their design proposals by modelling their ideas in a variety of ways
to develop a clear idea of what has to be done, planning how to use materials, equipment and processes, and suggesting alternative methods of making, if the first attempts fail
to evaluate their design ideas as these develop, indicating ways of improving their ideas and to evaluate the book against the original design criteria

Year Five

to recognise the movement of a mechanism within a toy or model
to understand that a cam will change rotary motion into linear motion
to understand that different shaped cams produce different movements
about the relationship between a cam and a follower
to measure and mark out accurately
to use tools for cutting safely and effectively
to use a drill to make an off-centre hole in a wheel
to consider the characteristics of the cam mechanism when designing the moving part of their toy
to test out their design ideas before proceeding
to cut and join with accuracy to ensure a good-quality finish to the product
to test the mechanisms and make adjustments where necessary
how to evaluate it personally and seek evaluation from others

There is no specific mechanisms work in Year 6
