The exam evaluates concepts in biology, chemistry, and physics, focusing on nutrient functions, thermal energy transfer, gas behavior, and reactivity of metals with acids. Key topics include adaptations in species, the effects of air resistance, pollination mechanisms, and energy conservation. Practical skills are assessed through calculating moments, interpreting sound waves, and exploring planetary orbits. Questions emphasize the Periodic Table, atomic structure, and photosynthesis rates. Environmental science concepts such as species extinction and energy efficiency are included. Keywords: biology, chemistry, physics, STEM education, energy transfer, reactivity series, adaptations, atomic structure, photosynthesis, environmental science.
