The exam assesses biology, chemistry, and physics topics, focusing on living organism characteristics, chemical reactions, energy transformations, and solubility rules. Key concepts include blood vessel functions, energy resource trends, plant water absorption, and reactivity of metals. Investigations explore current in electrical circuits, pulse rates after exercise, thermal energy changes, and anomalous results in distance-time graphs. Practical applications include pie chart analysis for energy trends, celery experiments for water absorption, and identifying insoluble salts. Keywords: biology, chemistry, physics, STEM education, energy transformations, reactivity series, solubility, water absorption, energy resources, experimental design.
