The exam evaluates biology, chemistry, and physics concepts, focusing on renewable energy, chemical reactions, and sound wave properties. Key topics include plastic pollution′s ecological impacts, energy transfer efficiency, light filtration, and forces on pivots. Investigations assess selective breeding, heat transfer in food burning, and fossil formation. Practical applications involve calculating moments, atomic structures, and the effects of distance on sound amplitude. Questions emphasize environmental conservation, experimental design, and understanding energy transformations, material properties, and ecological relationships. Keywords: biology, chemistry, physics, STEM education, renewable energy, energy transfer, sound waves, experimental science, plastic pollution, forces, atomic structure.
