The exam evaluates concepts in biology, chemistry, and physics, focusing on the alimentary canal, types of rocks, selective breeding, and atomic structure. Key principles include sound wave properties, energy transfer, and gas behavior. Investigations explore pollination, thermal conductivity, and the cooling of liquids. Applications cover selective breeding in chickens, adaptations in elephants, and pressure calculations in physics. Topics emphasize scientific reasoning, practical skills, and data interpretation. Keywords: biology, chemistry, physics, alimentary canal, selective breeding, sound waves, atomic structure, energy transfer, thermal conductivity, STEM education, pollination, pressure calculations.
