Polluting the atmosphere REVISION

This short revision lesson (@15-20 minutes) challenges students to recall the names of specific pollutants and match them to the issues they cause. 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 chemistry.

Student responses to questions about the products of the combustion of fuels are often too generic, where pollution is used as a blanket term to describe a range of gases. Therefore, this lesson has been written to support students to recognise carbon dioxide, carbon monoxide, sulfur dioxide, oxides of nitrogen, and particulates, and to name the issues related to their release into the atmosphere. The lesson is filled with understanding checks in the style of exam questions and all answers are embedded into the PowerPoint to allow students to assess their understanding and progress. The key points associated with the topic have also been displayed on a resource which can be kept with the understanding checks for use in the final days and hours before the exam.

Short revision lessons which follow a similar format have also been uploaded, and the short topics covered include sex determination, half-life graphs, and calculating the mean.
