The exam evaluates biology, chemistry, and physics concepts, including nutrient functions, photosynthesis, and states of matter. Key topics cover sound wave frequencies, plant adaptations, star patterns, and soil pH. Investigations include displacement reactions, pressure calculation, and forces in sports. Practical applications assess variables affecting photosynthesis, the decay of leaves, and electrical circuit analysis. Questions emphasize experimental design, data interpretation, and identifying mixtures at the molecular level. Keywords: biology, chemistry, physics, STEM education, nutrient functions, displacement reactions, sound waves, photosynthesis, soil pH, forces, experimental science, electrical circuits.
