In this unit, pupils will review and extend their knowledge of forces and machines. Pupils will develop an understanding of some basic concepts of physics and explore a variety of machines designed to make our lives easier. Pupils begin by refreshing what they know about forces, such as pushes and pulls, and simple and complex machines. 

Pupils will identify common machines that make life easier at school and make a poster of machines found in the home. Pupils are introduced to six simple machines and look at their parts to understand how they work. Pupils can use this information to identify the simple machines that make up complex machines in the world around them. This is followed by an opportunity for pupils to practise putting things together and taking them apart, while exploring the uses of simple tools. A second handson activity challenges pupils to work collaboratively to plan, design and make a machine. 

This activity aims to consolidate much of what the pupils have learned about simple machines and using simple tools while also providing concrete experiences for pupils to develop critical and creative thinking skills. The vocabulary in this unit will provide pupils the opportunity to build on content specific language that will help them understand and explain new concepts. This unit provides pupils with a variety of valuable opportunities to develop scientific skills including observation, planning, problem-solving, inventing and manipulating a variety of objects in their world.
