Children should learn that simple levers and sliding mechanisms can be used to create movement, that levers are used in products eg scissors, balances and moving books and to use drawings to represent products.
Children should learn 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 and to evaluate their product by discussing how well it works in relation to the purpose. This is lesson 3 in unit of work.
Children should learn that construction kits can be used to try out ideas, to make simple sliding and lever mechanisms and how to use tools eg scissors and a hole punch safely. This is lesson 2 in a unit of work.
Children should learn 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 and to understand the need for a stable structure to support a mechanism. This is lesson 3 in a unit of work.
Children should learn to use existing fabric designs as inspiration for their own pattern-making, to develop and communicate their design ideas through drawing and modelling and to make and/or use a simple paper pattern/template. This is lesson 3 in a unit of work.
