The experiments have been adapted from those used in workshops for pupils aged 7-11 years by The Making Place or are taken from That's Chemistry by Jan Rees. That's Chemistry was produced as part of the Royal Society of Chemistry's programme of support for education and a copy was sent free of charge to every primary school in the UK in 2001 with support from ABPI. Further information about this resource, together with details of how to order further copies, may be found here.

Guidance is provided for activities that require a particular awareness of safe working practices. Teachers should use their knowledge of their pupils' capabilities to select appropriate practical work for them to do.
