The Science series has been written to meet the full requirements of the current New Standards-based curriculum by the National Council for Curriculum and Assessment (NaCCA) with a critical thinking approach to learning Science. The series consists of a Learner’s Book, Workbook and Teacher’s Guide. Science Primary 1 is well crafted to ensure that the core values (core competencies) of the Standards-based curriculum are imbued in learners. The trials are based on the lessons taught under each indicator. This offers extra exercises for learners to practise and consolidate the lessons they have learnt.
