The exam evaluates biology, chemistry, and physics concepts, including plant reproduction, food webs, sound waves, and the solar system. Key topics cover displacement reactions, electrical circuits, and animal adaptations. Investigations assess rock formation, states of matter, and anomalous results in experiments. Practical applications focus on the Periodic Table, density calculations, breeding plants, and energy transfer in food chains. Questions emphasize experimental design, data interpretation, and understanding interactions between environmental factors and organisms. Keywords: biology, chemistry, physics, STEM education, displacement reactions, food web, sound waves, electrical circuits, experimental science, rock formation, solar system.
