This booklet supports a series of lesson and is designed for Entry Level/SEND students to allow them to access the key elements of science. If used in a mixed ability class, these booklets allow students to keep pace with the rest of the class whilst personalising the challenge and support they require. The booklet is part of a series of booklets with a variety of tasks including matching keywords and definition, scaffolding, extended answers, research and a lot of practical work with matching results tables/graphs. Some of the diagrams have had to be removed for copyright.

A range of revision activities for KS3 Can be used as starters, plenaries, homework and/or for independent revision.
