The exam evaluates biology, chemistry, and physics concepts, including plant organs, adaptations in desert organisms, and characteristics of rocks. Key topics are reaction rates, selective breeding, sound wave properties, and the behavior of light. Investigations emphasize plant growth with fertilizers, magnetic field patterns, and gas production in reactions. Practical applications include analyzing distance-time graphs, interpreting Periodic Table data, and the refraction of light. Keywords: biology, chemistry, physics, STEM education, plant organs, reaction rates, light refraction, sound waves, magnetic fields, selective breeding, adaptation, experimental science.
