  • FOCUS / ARONGA

    FOCUS / ARONGA learning intentions:

    • We are FOCUSING...on changing states of matter
    • We are FOCUSING...on separating mixtures
    • We are FOCUSING...on comparing mixtures and solutions


    Success Criteria: I can/have:

    • identify mixtures
    • separate mixtures by filtering
    • define the terms solvent, solute, and solution
    • separate solutions by evaporation
    • define the terms dilution and concentration


    Activities:

    - investigating solubility of sodium hydrogen carbonate and sodium chloride: which is more soluble in water? We will investigate this by dissolving tablespoons of each in water one at a time until no more dissolves. 

    - Worksheet on solutions on GC: what are the definitions of solute, solvent, mixture, solution etc. Name things tha can and cannot dissolve in water

    - Making a dilution series with potassium permanganate
