Chemistry: Concept & Reactions

Chemistry introduces students to the composition, properties, and transformations of matter. Through structured lessons, problem-solving, and lab-based investigations, students study atomic theory, bonding, reactions, stoichiometry, and the behavior of gases, liquids, and solids. Emphasis is placed on scientific reasoning, quantitative analysis, and real-world applications of chemistry. The course uses openly available instructional materials aligned to secondary science standards and supports both conceptual understanding and practical laboratory skills.
