  • 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:

    - evaporation of sodium sulphate over a bunsen burner - what can we see changing? What are we separating?

    - learning about the techniques used for separating mixtures

    - marker pen chromatography: separating mixtures of ink by using solvents such as glass cleaner and acetone
