Formulae and equations

This topic brings together some of the ideas that will allow students to make sense of the substances they will use in practical work and calculations they may make as part of the T level course. Students often find it difficult to picture the abstract concepts involved and it helps to give models (including mathematical relationships) to make sense of what they are seeing or using.  It is  probably helpful to use the diagnostic questions to identify what students may already think from other key stages, and then build on this with simulations and practice activities to look at relevant examples of where we would see that concept in action. It may also be helpful to look through other part of the qualification to identify links to where calculations are used again e.g. concentration when looking at serial dilutions or titrations and make these explicit to students as it is taught.       

Whilst this list provides a source of information and ideas for experimental work, it is important to note that recommendations can date very quickly. Do NOT follow suggestions which conflict with current advice from CLEAPSS, SSERC or other recent safety guides. eLibrary users are responsible for ensuring that any activity, including practical work, which they carry out is consistent with current regulations related to Health and Safety and that they carry an appropriate risk assessment. Further information is provided in our Health and Safety guidance.
