Contents include: scientific method, science process skills and organising the work.

It sounds a bit stuffy but it isn't. The presentation is clear, the  photocopiable worksheets are good, diagrams  well done and the content is age appropriate. Each activity is set out as a question followed by a 'scene setting' the materials you need, procedure, extension work and a conclusion.
