Identify the source safely
1 · Learn
Many appliances use electricity, including lamps, televisions and battery-powered toys. Some use cells or batteries; others connect to mains electricity.
Identify power sources from safe external observation or adult-provided pictures. Children should never open appliances, touch sockets or experiment with mains electricity. Practical circuits use approved low-voltage classroom equipment only.
2 · Worked example
I recognise a torch as electrical even when it is not plugged into a wall, because its battery supplies electrical energy.
3 · Your turn
Must every electrical appliance be plugged into a wall socket?
Check your answer
No. Some are powered by cells or batteries, or other suitable electrical sources.
4 · Apply your learning
Sort pictures by their stated power source with an adult. Explain uncertain examples rather than dismantling anything to find out.
Adult guidance and safety
Do not touch plugs, sockets, damaged leads or internal appliance parts. No mains experiments.

Typed notes are not submitted answers.
My observation notebook
With an adult, look at a safe real example or a checked photograph. Name the example and say which you used. Record what you actually notice. Do not taste plants or materials, approach unknown animals or invent missing observations.
Ask your teacher for support with the method and recording. A prediction is what you think might happen; an observation is what you actually see, hear or feel safely.
Keep your notebook: use Download notebook before leaving. Nothing is sent to the website or saved to your account. Reopen the downloaded notebook here to add another day's record. Do not include names, addresses or other private information.
Your records on this page
No observations recorded yet. Look first, then add one.
Reopening adds records; it does not replace your current records. Up to 50 records per notebook. Keep your downloads somewhere private. Editing this notebook does not submit work or complete a lesson.
