The exam evaluates biology, chemistry, and physics concepts, including cell structures, states of matter, and photosynthesis. Key topics explore the Sun-Earth-Moon system, plant reproduction, chemical reactions, and sound wave properties. Investigations assess light intensity effects on carbon dioxide levels, temperature changes in reactions, and electrical circuits. Practical applications involve calculating density, analyzing nutrient deficiencies, and tracing life on Earth timelines. Questions emphasize data interpretation, experimental design, and understanding of energy transfer and material properties. Keywords: biology, chemistry, physics, STEM education, photosynthesis, reaction rates, density calculation, plant reproduction, experimental science, energy transfer.
