Radiation

This Nuffield Pathways Through Science module introduced a source detector model for thinking about radiations. This model was used as students explored the transmission, absorption and reflection of radiation and then went on to learn about the radiations from radioactive materials. The module also investigated the formation of images by lenses and mirrors. It ended with the wave model of light and other electromagnetic radiations. The module was presented in three episodes:
Ra 1: Types of radiation
Ra 2: Images
Ra 3: Waves

The Teachers’ Guide included an outline of the rationale adopted for teaching about radiation and radioactive materials.

*Study Guide – to help teachers and students with planning, record keeping and revision.
*Activities – 62 sides of copiable activities as the basis for a differentiated programme of learning
*Commentary - offering hints and answers. When in difficulty students could get help from the commentary; if their experiment went wrong they could find sample results; if they were absent they could discover the outcomes of the activities they had missed.
*Sourcebook – a highly-illustrated and diverse source of information, explanations and stories. The Sourcebook complemented the activities. Some activities were served directly by features in the Sourcebook. Other features help to set the episodes of the module in context. Some activities directed students to a specific page or feature. More challenging activities required students to scan more of the pages in search of the information they need.
*Teachers’ Guide – with notes on teaching strategies and technical information about all the activities
