The exam evaluates biology, chemistry, and physics concepts, including the circulatory system, particle behavior during freezing, and the solar system′s structure. Key topics cover adaptations in desert plants, food chains, reaction rates, and energy transfer in circuits. Investigations focus on making salts, photosynthesis, mineral transport in plants, and the effect of acid concentration on gas production. Practical applications assess toad population impacts, fossil destruction in metamorphic rocks, and speed calculations in motion graphs. Questions emphasize experimental design, data interpretation, and understanding processes in natural and physical sciences. Keywords: biology, chemistry, physics, STEM education, photosynthesis, reaction rates, circuits, experimental science, adaptations.
