The exam evaluates biology, chemistry, and physics topics, focusing on selective breeding, natural selection, reaction rates, and energy transfer. Key concepts include plant water transport, sound reflection, and cell adaptations. Investigations explore temperature changes in chemical reactions, the properties of charged objects, and the energy efficiency of systems. Practical applications emphasize rock formation, adaptations of camels, and evaporation. Questions highlight scientific reasoning, data interpretation, and experimental design. Keywords: biology, chemistry, physics, STEM education, selective breeding, energy transfer, natural selection, reaction rates, adaptations, scientific investigation, thermal energy, plant physiology.
