Units / Unit A
Energy and Matter in Chemical Change
Nature of ScienceTeachableChemical changes involve energy and transformations of matter. Students explore molecular and ionic compounds, acids and bases, classification, nomenclature, balanced equations, conservation of mass, and the mole concept.
Focusing questions
- How has knowledge of the structure of matter led to other scientific advancements?
- How do elements combine?
- Can these combinations be classified and the products be predicted and quantified?
- Why do scientists classify chemical change, follow guidelines for nomenclature and represent chemical change with equations?
Key concepts (POS)
- WHMIS and safe practices
- IUPAC nomenclature
- ionic and molecular compounds
- acids and bases
- evidence of chemical change
- writing and balancing equations
- law of conservation of mass and the mole concept
