Keys and Detection
Work done in this Nuffield 13 - 16 module followed from the B units called ‘Communities and populations’ and ‘Charged particles’. This S unit provided enough material for eight double periods during a single-certificate science course. The teachers’ guide included four worksheets to supplement the students’ booklet.
The main aims of this module were:
1. to encourage students to use different types of keys, in a confident and knowledgeable way, to identify a range of materials and living organisms;
2. to help develop students’ observational and practical skills.
It was hoped that by understanding how keys work, students would be able to construct their own keys where appropriate.
