Chemistry Experiments contains a varied collection of labcards and worksheets from which teachers can choose in order to build up a programme of chemistry practical work for use in the school laboratory. The labcards include labelled diagrams and questions which are designed to help guide students through the writing-up process.
The labcards give instructions for a wide variety of practical experiments and demonstrations to support chemistry teaching, grouped into themes.
