The SWL Integrated Science for Primary Schools Books 4-6 are based on the current syllabus for Integrated Science for Primary Schools, issued by CurriculumResearch and Development Division (CRDD) of the Ministry of Education. The books contain carefully selected learning activities and well designed science experiments and exercises. They are highly illustrated in full colour to make the learning of science interesting and meaningful. A glossary at the end of each book provides explanations to some words used in the books. The books will help pupils to build a firm foundation for the study of science.
