The exam evaluates concepts in biology, chemistry, and physics, covering cell functions, energy types, rock hardness, and the respiratory system. Key principles include light filtration, heart rate patterns, density calculations, and natural selection. The Periodic Table is applied to understand atomic structure and chemical reactions, while thermal energy transfer mechanisms are explored through convection, conduction, and radiation. Practical investigations focus on photosynthesis, acid-carbonate reactions, and using indicators for acids. Keywords: biology, chemistry, physics, natural selection, energy transfer, density, atomic structure, chemical reactions, STEM education, photosynthesis, periodic table.
