Play Year 4 Electricity Lab
Identify electrical appliances and outputs, choose safe responses, name simple circuit components and reason about complete low-voltage loops. Saving is off unless you choose it.
Choose predictions and possible faults from supplied low-voltage circuit descriptions. Drawing, building, testing and independently diagnosing real circuits are not assessed.
Year 4 · Science
Simple Circuits
Start here
Focus on building a simple electric circuit. Open support for “Explore Electrical Circuits”, then explain the idea in your own words.
Year 4 learners practise building a simple electric circuit.
The activities include Explore Electrical Circuits, Explore the Different Parts of Electrical Circuits, Identify the Cause of Problems in Electrical Circuits, and related practice. The checked support below includes video, teaching-practice, lesson, worksheet. Open a resource in its provider's website and choose the format that best helps the learner explain the idea independently.
