Tips and resources to help you teach chemical processes and organic reaction mechanisms
PracticalElectrochemical cells | practical videos | 16–18 students
Video and supporting resources to support electrochemistry practical work, including two microscale experiments, animation and cell diagrams
ExperimentThe ‘breathalyser’ reaction | 16–18 years
Try this demonstration to recreate an early ‘breathalyser’ test, passing ethanol vapour through potassium dichromate. Includes kit list and safety instructions
ResourceSwimming pool chemistry | 16–18 years
Synoptic questions explore structure and bonding, equilibrium and spectrometry and spectroscopy in the context of swimming pools
ResourceRusting: a lateral thinking problem | 11–14 years
Learners apply their knowledge of rusting in the context of shipwrecks. A lateral thinking exercise and planning an investigation will help them develop higher-order skills.
ResourceCandle burning investigation: planning an experiment
Concept cartoon and example investigation to practise developing a hypothesis, planning an investigation and evaluation skills
