A powerpoint and worksheet based on Breaking Bad and the production of methamphetamaine. Students are given two key equations and must then work through a variety of problems completing calculations involving relative formula mass, percentage by mass, moles and mass, ratios, and percentage yield. Worksheet is differentiated by Foundation and Higher.

A level-assessed task similar to the old KS3 AF tasks where students are tasked with designing a portable solar still (a device used to generate clean drinking water through evaporation and condensation). This task provides a relevant and important context for the types of separating techniques discussed during this particular topic as it is a current research area where a lot of funding is allocated by companies such as BP. Also included are tips and a proforma for time-efficient marking and feedback of said task to minimise teacher workload.
