The exam assesses key scientific concepts in biology, chemistry, and physics. Topics include arthropod classification, energy conservation, chemical formulas, and the reactivity series. Environmental issues such as carbon dioxide emissions and renewable fuels are explored alongside practical applications like diffusion, endothermic reactions, and the principle of moments. The properties of Group 7 elements, sound wave behavior, and planetary distances are analyzed through data interpretation. Questions emphasize experimental design, critical thinking, and problem-solving. Keywords: biology, chemistry, physics, environmental science, energy conservation, periodic table, sound properties, planetary science, STEM education.
