Electricity Explorers

Overview

Students are introduced to electricity as a form of energy used to meet needs and solve problems. They identify common electrical sources and uses, learn essential safety rules, and construct a simple low-voltage circuit to investigate what is needed to make a lamp light.

Learning intentions

Students will:

• identify common sources and uses of electricity
• explain that a circuit must be complete for electrical energy to make a lamp light
• plan and conduct a simple, safe investigation
• record observations in a table and communicate a conclusion using scientific vocabulary

Success criteria

• I can name electrical devices and describe what they are used for.
• I can identify a battery, wires, lamp and switch in a simple circuit.
• I can build a complete circuit safely and explain why the lamp lights or does not light.
• I can record my observations and write a conclusion.

Curriculum links

• Science Understanding — identifying sources of energy and examining how energy changes or transfers between objects.
• Science Inquiry — using a scaffold to plan and conduct an investigation, identify fair-test elements and use materials safely.
• Science as a Human Endeavour — considering how people use scientific explanations to meet a need or solve a problem.
• Science Inquiry and Communication — organising observations in tables and communicating findings using scientific vocabulary.

Lesson structure (60 minutes)

1. 0–7 min · Hook and prior knowledge. Teacher displays the opening electricity question showing a dark room with several familiar devices and asks, “How could we make this room useful again?” Students think-pair-share examples of devices that use electricity, then contribute ideas to a class list. Emphasise that electricity is useful energy, but it can also be dangerous when used incorrectly. Explain that today’s practical work uses batteries only, never wall sockets.

2. 7–17 min · Direct teaching and safety. Teacher uses the electricity and safety slides to introduce electrical sources such as batteries, the Sun and power stations, and electrical devices such as lamps, fans and computers. Model the words battery, energy, circuit, complete, component and switch, and explicitly demonstrate: follow instructions, keep water away, handle equipment carefully, check wires before connecting, and never put equipment near mouths or eyes. Students help identify safe and unsafe choices and sort examples with the safety symbols sorting cards. Review the class rule: stop, disconnect and tell the teacher if equipment becomes hot, damaged or behaves unexpectedly.

3. 17–25 min · Model a circuit. Teacher uses the circuit diagram and prediction slides while slowly modelling a battery connected by wires to a small lamp. Show a complete loop and then deliberately create an open circuit by removing one connection. Ask, “What changed, and why did the lamp stop?” Students make an individual prediction on the electricity investigation worksheet: “The lamp will light when…” They label the battery, wires, lamp and switch on the simple diagram.

4. 25–43 min · Practical investigation. Teacher places students in groups of four with a battery holder, low-voltage battery, lamp and holder, wires and switch. Assign roles: equipment manager, builder, recorder and safety checker; rotate roles if time permits. Give the investigation question: “What must be connected for the lamp to light?” Keep the battery type and lamp the same while groups test one change at a time, such as a complete loop, one wire disconnected, or the switch open and closed. Students construct and test circuits, disconnecting the battery when not actively testing. They record the arrangement, prediction, observation and result in the table on the electricity investigation worksheet. Circulate and ask: “What are you changing?”, “What are you keeping the same?”, and “How do you know the circuit is complete?”

5. 43–53 min · Represent and explain findings. Teacher pauses the practical work and uses the results and explanation slides to model a simple results table and a labelled circuit drawing with arrows showing the closed path. Invite two groups to demonstrate a working and non-working arrangement, without touching another group’s equipment. Students complete the worksheet conclusion: “The lamp lit when… It did not light when… This shows that…” They add a labelled drawing of their successful circuit and use the words complete circuit, energy, battery and component.

6. 53–60 min · Plenary and assessment. Teacher uses the final review slides for a quick “Which explanation is best?” activity: students show thumbs up, sideways or down for statements such as “A battery alone makes a lamp light” and “A complete circuit is needed.” Revisit how electricity helps people meet needs, such as lighting, communication and cooling. Students complete the final three questions on the electricity investigation worksheet and hand it in as their exit response: name one electrical source, draw a complete circuit and state one safety rule.

Resources

• the electricity introduction and investigation slide deck
• the electricity investigation worksheet
• the safety symbols sorting cards
• One low-voltage battery and holder per group
• Small torch lamps and holders
• Insulated connecting wires and simple switches
• Safety goggles, paper towels and equipment trays
• Whiteboard and markers

Assessment

• Listen to student explanations during the hook, safety sort and circuit modelling; note whether they use source, component, complete and circuit accurately.
• Observe group investigations using a checklist: follows safety instructions, changes one feature at a time, records observations and explains the result.
• Use the worksheet and exit response to assess whether students can identify a complete circuit, represent it visually and communicate a conclusion.

Differentiation

• Provide a partially completed circuit diagram, picture vocabulary and sentence starters: “The lamp lit because…”, “We kept ___ the same…” and “Our test was safe because…”
• Pair students strategically and allocate practical roles; provide pre-connected leads or an adult-supported group for students who need fine-motor or organisational assistance.
• Allow EAL/D students to rehearse explanations orally with a partner before writing and use labelled photographs alongside words.
• Extend confident students by asking them to add a switch to their circuit, predict its effect before testing, and explain why the switch controls the lamp without changing the battery or lamp.
