The exam focuses on key scientific topics including plant life cycles, sound properties, food chains, methods of separating mixtures, light behavior, living and non-living classification, electrical circuits, melting points, environmental impact, and human anatomy. It emphasizes experimental design, data analysis, and applying concepts of forces, planetary motion, material properties, and skeletal growth. Skills assessed include identifying relationships in food webs, explaining energy transfer, drawing light rays, and interpreting graphical data. Keywords: plant reproduction, sound, food chains, mixtures, light, living organisms, circuits, melting points, environment, anatomy, forces, skeletal growth, planetary motion.
