Hi, I am a volunteer teacher from the UK working for a charity (a home for girls from underprivileged backgrounds) in South East Asia. My pupils are working roughly to iGCSE/KS3 level and we have kindly been granted use of the local university labs for running science practicals. I am not a trained technician and cannot enable any support for drafting specific technician instructions that I am struggling with. Does anyone know of a guide I can purchase or better still download off-line (for free since we are a charity)? or possibly email me technician notes for iGCSE science/chemistry. Any help is much appreciated.
