This Teacher's Resource Book will ensure you can deliver the Cambridge Secondary 1 programme for Science with confidence. It offers detailed support with the practical aspects of the course, and includes plenty of homework activities and worksheets. To help prepare your students for the examination there are sample Checkpoint Tests for use at the end of the relevant stage, with full mark schemes.Biology, Chemistry and Physics are combined in a single handy volume, but the material is in three distinct sections so you can still teach the course as three separate Sciences if you prefer.
