  • FOCUS / ARONGA

    FOCUS / ARONGA learning intentions:

    • We are FOCUSING...on identifying the chemical and physical changes used in Halloween (and other holiday) decorations so wen can develop our own decorations
    EXPLORE / TŪHURA

    EXPLORE / TŪHURA learning intentions:

    • We are EXPLORING...how matter changes between states so we can interpret and integreate their uses into society (eg. Halloween)
    • We are EXPLORING... chemical and physical changes by experimenting with different materials used in holiday decorations
    Context: Halloween

    Success Criteria:

    - Investigate chemical changes used in special effects, including fire works, so we can apply and make our own special effects or decorations

    - Record detailed observations to draw simple conclusions and ask deeper questions

    Keywords: chemical change

    Activities:

    Practical: investigate conductivity of liquids, examine a candle to identify chemical vs. physical changes, explore other chemicals to identify signs of chemical changes

    Literacy: Google Classroom (Properties of materials worksheet) 

    In-class: Demo of chemical changes
