Year 5

Introduction lesson: understanding electrical systems

In this lesson, we will introduce you to the unit 'Control'. We will explore what electrical systems are and revisit simple circuits. We will explore what inputs, processes and outputs are on an electrical system. This lesson includes some physical activity and equipment beyond pen, paper or pencil. Please make sure your child is adequately supervised.
