The exam evaluates biology, chemistry, and physics concepts, focusing on plant cell functions, chemical reactions, and air pressure effects on breathing. Key topics include photosynthesis, metal reactivity, displacement reactions, and evaporation. Investigations address sound wave compressions, reaction rates, and the principle of moments. Practical applications assess electrical circuits, the composition of blood, light dispersion, and sorting elements, compounds, and mixtures. Questions emphasize experimental analysis, data interpretation, and understanding of energy transformations. Keywords: biology, chemistry, physics, STEM education, plant cells, metal reactivity, photosynthesis, evaporation, electrical circuits, energy transformations, experimental science.
