Exploring Science adopts the thematic approach required by the new NERDC curriculum. In this approach, four themes are considered. The themes are Learning about our environment, Living and non-living things, Understanding technology and You and energy. They are all well-treated. In this fifth book of the series, each theme is divided into chapters and units. Theme 1 has six chapters: Environmental changes, Waste and waste disposal, Environmental quality, Disease, The human body (The skeleton) and Domestic animals with twenty-three units. Theme 2 has five chapters: Reproduction in plants, Water cycle, Rocks, Acids and bases, and Soap making with twenty-four units. Theme 3 has six chapters: Materials and maintenance, Basic internal parts of a motor vehicule, Safety in our environment, Artifical Intelligence (AI), 5G network and Drawing instruments with nineteen units while Theme 4 has four chapters: Energy conversion, Heat and temperature, Basic electricity and Magnetism with nineteen units. The chapters are structured to make their contents interactive to the pupils, beginning with objectives followed by keywords where pupils learn the major scientific words they are bound to come across in the course of their study and multiple activities that will help their interaction with the processes of approach, observation, manipulation, inquiry, experimenting and grouping or classifying. There is also revision exercises which will help to test the assimilation and understanding of what was taught in each chapter. Teachers who are the facilitators of learning and organisers of interaction between pupils and objects in the environment, will find this resource material very relevant and useful, while pupils will find it captivating such that a positive attitude towards the study of science and technology is instilled.
