In this lesson, we will be learning all about static electricity. We will learn how static charges occur and what happens when they are discharged. We will also be exploring how to create our own static charges with a balloon! If you have a balloon at home then you can use it for this lesson. If you don't then don't worry, you will still be able to watch the demonstrations and complete the lesson.
Unit Overview: Electrical circuits
- Identify common appliances that run on electricity
- Construct a simple series electrical circuit, identifying and naming its basic parts, including cells, wires, bulbs, switches and buzzers
- Identify whether or not a lamp will light in a simple series circuit, based on whether or not the lamp is part of a complete loop with a battery
- Recognise that a switch opens and closes a circuit and associate this with whether or not a lamp lights in a simple series circuit
- Recognise some common conductors and insulators, and associate metals with being good conductors.
- Associate the brightness of a lamp or the volume of a buzzer with the number and voltage of cells used in the circuit
- Compare and give reasons for variations in how components function, including the brightness of bulbs, the loudness of buzzers and the on/off position of switches
- Use recognised symbols when representing a simple circuit in a diagram.
In this lesson, we will learn how to build an electrical circuit. We will look at all the different components of an electrical circuit and learn the rules for building them. You will need a piece of paper, a pencil and a ruler for this lesson.
In this lesson, we will be learning how electrical circuits are represented as diagrams. We will learn the symbol for each component and draw our own circuit diagrams. You will need a pencil, a piece of paper and a ruler.
In this lesson, we will learn what an electrical conductor and an electrical insulator are. We will conduct an investigation to see which materials are insulators and which are conductors. Finally, we will draw conclusions about the best material to make certain objects from, based on what we have learnt. You will need a piece of paper, a pencil and a ruler.
In this lesson, we will be learning about voltmeters and ammeters. We will then investigate what happens when we change the number of cells and lamps in a circuit. We will be writing predictions and conclusions in this lesson. You will need a pencil, a piece of paper and a ruler.
In this lesson, we will learn about mains and battery electricity. We will identify and sort appliances based on whether they are electrical or non-electrical and also whether they are powered by mains or battery electricity. We will explore the idea of a world without electricity.
