Structures

• to investigate, disassemble and evaluate a range of musical instruments in order to learn how they function  

• to relate the way things work to their intended purpose, how materials and components have been used, people’s needs, and what users say about them

• how the working characteristics of materials relate to the ways materials are used  

• how materials can be combined and mixed in order to create more useful properties  

• to join and combine materials and components accurately in temporary ways  

• to investigate a range of materials 

• to identify a purpose for their instrument  

• to use information sources, including ICT,  to help in their designing  

• 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 select appropriate materials, tools and techniques  

• to evaluate their design ideas as these develop, bearing in mind the users and the purposes for which the product is intended, and indicating ways of improving their ideas  

Mechanisms

• 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

Electrical / Control

• that there are a variety of products which incorporate a pulley and a drive belt and are driven by a motor or a computer  

• how control systems are used in everyday life  

• the appropriate vocabulary related to control systems  

• that they can model their ideas for their own product using mechanisms, by using construction kits or making a model from a set of instructions  

• how to include an electric motor in a simple circuit  

• how the direction of rotation and speed of an electric motor can be controlled  

• how rotation can be transferred from one part of a model to another by using pulleys and a belt  

• how a belt and pulley system can reverse the direction of rotation (by twisting the belt through 180 degrees)  

• how a belt and pulley system can turn the plane of rotation through 90 degrees (by twisting the belt through 90 degrees)  

• how a belt and pulley system can increase or decrease the speed of rotation (by using different size pulleys)  

• to make decisions with regard to the type of ride they will make  

• to model their intended fairground ride  

• to make modifications as they go along  

• to evaluate against their original criteria and suggest ways that their ride could be improved
