    Context: Taking the Leap



    FOCUS / ARONGA learning intentions:

    • We are FOCUSING...defining terms relating to sound, waves and energy
    • We are FOCUSING...describing and explaining how sound is produced and travels in different medium
    >Success Criteria    :        I can/have:
    • an understanding of the terms related to sound
    • begin to have an understanding of the properties of sound - how it travels and as a form of energy
    • relate sound to everyday living giving suitable examples
    • made a record observations in my science book of experiments done in the lab.
