Knowledge and Understanding of Science: Chemical Changes

The resource for teachers Knowledge and understanding of science: chemical changes, published in 1994 by the School Curriculum and Assessment Authority, (taking over the responsibilities for the curriculum from the National Curriculum Council), provides background scientific knowledge and understanding for teachers. It is not intended or suitable for direct use with pupils. It begins with a warning about safety and the recommendation for teachers to read the safety section on pages 3-4. The Association for Science Education's (ASE) book Be safe . The following sections are grouped into two main parts: Sections 1-7 cover levels one to five of the National Curriculum, and Sections 8 and 9 cover levels six and seven of the National Curriculum science Order.

Each section includes tasks, which require teachers to think about a situation or carry out a practical activity. Summaries outline the main points of the text at strategic positions throughout a section. Resource lists also appear where applicable.

The reader is involved in self-assessment with explanations throughout the text. At key points in the book there are self-assessment sections. Each activity refers the reader back into the appropriate sections of the text if difficulties are encountered.

HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
