Suggested practical apparatus: Combined Science Trilogy and Synergy

Transcription

1 Suggested practical apparatus: Combined Science Trilogy and Synergy Through their study of the new GCSE Sciences students must be given the opportunity to experience a wide range of hands-on practical work. Hands-on experience will help them acquire the practical skills defined by the DfE in their Apparatus and Techniques criteria. We have designed all the activities to use standard equipment and materials that can be found in most school laboratories. The lists are not exhaustive, and we encourage teachers to modify the activities to suit their students needs and learning objectives, and the resources available in their school/college. Risk assessment These required practical activities have been suggested by teachers who have successfully carried them out in the lab. However, it is the responsibility of the centre to ensure that full risk assessments have been carried out in each case. Trialling Teachers should trial the required practical activities to make sure that they are manageable and match the resources available in the school/college.
