The exam assesses scientific concepts including classification of organisms, material properties, forces, energy transfer, and environmental conservation. Key topics involve food chains, sound properties, seed germination, states of matter, shadow formation, human anatomy, and substance solubility. Questions emphasize experimental design, data interpretation, and the application of biological, physical, and chemical principles. Skills tested include separating mixtures, analyzing sound volume, identifying organ functions, and modeling the Earth-Sun relationship. Keywords: organism classification, material properties, forces, food chains, sound, seed germination, shadows, anatomy, solubility, energy transfer, mixtures, conservation.
