The exam evaluates biology, chemistry, and physics concepts, including the functions of cells, chemical reaction products, and the life cycle of plants. Topics include the respiratory system, energy resources like wind turbines, and properties of solids, liquids, and gases. Investigations explore the bending of rulers under weight, particle behavior in diffusion, and water pressure. Practical applications assess the reactivity of metals, temperature recording, and arthropod classification. Keywords: biology, chemistry, physics, STEM education, chemical reactions, energy resources, respiratory system, diffusion, water pressure, reactivity series, experimental science.
