Energy and Change
The approach and the materials called Energy and Change were developed during the project 'Teaching about why things change'. The work was done by Jon Ogborn and Richard Boohan from 1992 to 1995 and a grant from the Nuffield Foundation supported the development work. The project set out to devise simple, everyday and coherent ways of talking about thermodynamic ideas which are accessible to school students.
Energy and Change was published as a set of three booklets outlining a new approach which starts from commonsense ways of explaining why things happen. In developing these materials the authors had three important criteria in mind, namely, that the approach should be:
• intelligible to students
• useful to teachers
• scientifically consistent
The central idea
The central idea is that change is caused by differences, for example, differences in temperature or in concentration. To make these ideas intelligible to students, the project developed a range of abstract pictures. Some of these pictures could appear somewhat daunting at first, but the authors found that students were quickly able to become familiar with them, and were stimulated into a good level of discussion.
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.
