    I am brainstorming ideas for a Sound, Heat, Light enrichment unit for 2nd grade... I'm coming up short on experiment ideas for heat... would love to hear what you've done with your classes! thanks in advance!!


    Sound ideas:
    - Slinky activity to show wavelength, pitch, etc.
    - Tissue box guitars
    - Pitch bag scavenger hunt
    - Tuning fork in water to see sound waves
    - Straw activity to show change of pitch
    - Jumping to music – vibration activity with rice and sugar


    Heat ideas:
    - Which heats up the fastest?
    - Do things dissolve faster in hot or cold water?


    Light ideas:
    - Prisms
    - Bending light
    - See the light – shining flashlight through different solutions – do you see the light? You don’t see it in a solution.
    - light box to show refraction
    - drawing your shadow in the early morning, afternoon, late afternoon
    - rainbow light drawings

    This is an EASY one for heat. Using one of those mug warmers (the flat kind-- I usually use 3 of them so that we can do all 3 dishes at the same time), and 3 small glass dishes.... place in the 3 dishes: a pat of butter, a piece of chocolate, and a piece of ice.
    Have the children sketch pictures of what each item looks like. Then place the dishes on the warmers, and kiddos observe what happens. They then sketch the items at the end and write their hypothesis about why this change occurred (of course, they were discussing this as it happened, and they came up with the correct assumption).
    I make the recording sheet up on the computer so they have little boxes to draw their observations and a space to write their hypothesis.
    If you have time and the proper climate, you can do this using the heat of the sun rather than the warmers.
    Hope this helps!!

    By the way, at the end of my sound unit, I always have the kids do a special homework project where they make homemade instruments (for extra credit). I send home a list of suggestions to get them thinking.
    They LOVE it!!:p

    wrap one thermometer in black paper and one in white paper. set them in the sun for 30 minutes. track the temperature difference.

    the edu store here sells solar beads (change color in sunlight).

    If your classroom is heated with radiators, it should be easy to show the kids convection: use strips of tissue paper.
