The exam evaluates biology, chemistry, and physics concepts, focusing on plant cell structures, energy transfer, and respiratory processes. Key topics include selective breeding, sound wave properties, reactivity of metals with water and acids, and light refraction. Investigations explore weed killer concentrations, pH measurement, and gas composition differences during respiration. Practical applications assess the Periodic Table, magnetic field strength, and the splitting of white light. Questions emphasize experimental design, data analysis, and understanding of chemical properties and physical processes. Keywords: biology, chemistry, physics, STEM education, selective breeding, energy transfer, respiratory system, reactivity series, light refraction, experimental science.
