Units REVISION

This short revision lesson (@15-20 minutes) reminds students of the units for the physical quantities and supports them to convert between units. The lesson has been primarily designed for use with those students taking the AQA Combined Science FT in the lead up to mock and GCSE examinations, but is also suitable for students taking the HT, or separate science.

Although students are given the equations in the examination, in my experience, their knowledge of the different units isn’t great, and they can struggle to convert between units, so this lesson has been written to address those weaknesses. The lesson begins by challenging them to use the units for 4 quantities to reveal a boy’s name and then a series of understanding checks and a quick quiz will help them to recall more. In recent years, several questions on the physics papers have required students to recognise that a quantity is in the wrong unit and to convert before using in the equation. An exam-style question is modelled on the Powerpoint to show an example of this conversion and then the students will answer 2 understanding checks. All answers are embedded into the PowerPoint to allow students to assess their understanding and progress.

Other short revision lessons on science topics including relative formula mass, percentage by mass in compounds, mitosis vs meiosis and half-life graphs are uploaded.
