Lesson 1: Pivots, levers and linkages
Looking at every day objects, children learn that a lever is something that turns on a pivot and that a linkage is a system of levers that are connected by pivots
Looking at objects and understanding how they move
Understanding that mechanisms are a collection of moving parts that work together in a machine
Knowing there is always an The energy that is used to start something working. and Output is the motion that happens as a result of starting the input.... in a The parts of an object that move together as part of a machine....
Identifying mechanisms in everyday objects
Understanding that a lever is something that turns on a The central point, pin, or shaft on which a mechanism turns or swings....
Understanding that a Lengths of material (for example, metal or card) that are joined together by pivots, so that the links can move as part of a mechanism.... is a system of levers that are connected by pivots
Devising a class A set of rules to help designers focus their ideas and test the success of them.... for a Moving Monster
