## Spring - Electricity

This unit is the first introduction to studying electricity in Key Stage 2. You will learn about what electricity is and how it was discovered. You will identify which appliances use electricity in your homes and how to keep themselves safe. You will construct circuits, start to create pictorial circuits and conduct an investigation into how easily different types of switches can break and reconnect a circuit.

### Lesson 1 - Exciting Electricity

To report on findings, including oral and written explanations
in the context of preparing a presentation on how electricity is
generated.

• I can explain ways that electricity is generated.

### Lesson 2 - Electrical Appliances

Identify common appliances that run on electricity by learning
to distinguish between appliances that use and do not use
electricity, the different types of electricity and identify how to
stay safe when using electricity.

• I can identify electrical appliances and the types of
electricity they use.

### Lesson 3 - Electrical Circuits

Using results to draw simple conclusions, make predictions for
new values, suggest improvements and raise further questions.
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 by visualising and testing circuits to see if the circuit is
complete.

• I can identify complete and incomplete circuits.

### Lesson 4 - Conductors and Insulators

Construct a simple series electrical circuit, identifying and naming
its basic parts, including cells, wires, bulbs, switches and buzzers.
Making systematic and careful observations and, where
appropriate, taking accurate measurements using standard units,
using a range of equipment, including thermometers and data
loggers.

Recognise some common conductors and insulators, and
associate metals with being good conductors by testing different
materials as part of a circuit to see whether or not they conduct
electricity.

• I can identify and sort materials into electrical conductors
or insulators.

### Lesson 5 - Splendid Switches

Construct a simple series electrical circuit, identifying and naming
its basic parts, including cells, wires, bulbs, switches and buzzers.
Recognise that a switch opens and closes a circuit and associate
this with whether or not a lamp lights in a simple series circuit by
creating circuits which contain a switch.

• I can explain how a switch works and why they are
needed.

### Lesson 6 - Investigating Switches

Construct a simple series electrical circuit, identifying and naming
its basic parts, including cells, wires, bulbs, switches and buzzers.
Recording findings using simple scientific language, drawings,
labelled diagrams, keys, bar charts, and tables.

Reporting on findings from enquiries, including oral and written
explanations, displays or presentations of results and conclusions
in the context of making and investigating different switches.

• I can record and report on an investigation.
