As well as following the QCA Scheme of Work order, Catalyst Pupil Books provide you with a stimulating way to teach the five key scientific ideas from the Framework: cells, forces, particles, energy and interdependence. Green Pupil Books support lower-ability pupils, keeping them engaged and encouraged throughout each lesson. The larger text and carefully controlled language level make the pages more accessible for lower achievers. More regular in-text questions and the end-of-spread questions build up pupils' knowledge - and confidence - throughout the lesson. Red and Green books have identical pagination, so you can use them side by side in a mixed-ability class.
