    Chemical Reactions and Conservation of Mass

    Investigate chemical changes, analyze evidence of reactions, and understand the fundamental principle of mass conservation in chemical processes.

    Chemical Changes
    Conservation of Mass
    Reaction Evidence
    Energy Transfer
    Catalysts

    Essential Learning Outcomes & Chemical Understanding

    Essential Learning Outcome 1: Analyze and interpret data on chemical reactions to provide evidence that atoms are conserved during chemical reactions.

    Observable Evidence of Chemical Reactions:
    • Color changes in reactants and products
    • Gas production (bubbling or effervescence)
    • Temperature changes (heat release or absorption)
    • Precipitate formation (solid from liquid solutions)
    • Light emission or changes in luminescence
    • Odor changes or new smell production
    Data Collection Methods:
    • Before and after mass measurements
    • Temperature monitoring during reactions
    • pH changes using indicators
    • Visual observation and documentation
    • Gas volume measurements

    Detailed Curriculum Outcomes

    Comprehensive chemical reaction learning expectations
