Year 9 · Science
Energy efficiency, power and cost
Start here
Focus on calculating energy cost and power. Open support for “Calculate Energy and Cost of Electricity Bills”, then explain the idea in your own words.
Year 9 learners practise calculating energy cost and power.
The activities include Calculate Energy and Cost of Electricity Bills, Compare Advantages and Disadvantages of Different Energy Resources, Define and Calculate Power, and related practice. The checked support below includes video, worksheet, teaching. Open a resource in its provider's website and choose the format that best helps the learner explain the idea independently.
