The exam evaluates biology, chemistry, and physics concepts, including human anatomy, metal reactions, and adaptations in organisms. Key topics cover skeletal functions, air pressure effects, the electromagnetic properties of materials, and diffusion processes. Investigations explore sound wave analysis, rust prevention, and reaction rates of metals with acids. Practical applications assess stopping distances, solar system knowledge, and strengthening electromagnets. Questions emphasize experimental design, data interpretation, and understanding environmental adaptations and their implications. Keywords: biology, chemistry, physics, STEM education, anatomy, reaction rates, electromagnetism, diffusion, stopping distance, rust prevention, experimental science.
