    • Grade 4 Science Sound
    •  
    • What is Sound?
      • Our first step…brainstorming ideas!
      • I had the students think of words or anything that came to mind, when they think about “Sound”
      • There were lots of great ideas generated!
    •  
      • As a class we did the first 2 columns of the KWL chart together…
    • Vibrations
      • We had defined vibrations as something moving back and forth very quickly; vibrations create Sound
      • Then we moved onto our first experiment to test out vibrations!
    • Sound is Vibrations
      • Experiment # 1: To examine (hear and feel) sound vibrations!
      • Materials:
      • You will need- A Partner. A balloon.
      • Method: What you have to do-
      • 1) Blow up the balloon. 2) Hold it against your ear. 3) Ask your partner to press their lips against the balloon and speak. 4) Repeat steps 3 and 4 but this time you should speak and your friend should listen.
    • Frequency & Pitch
      • We defined pitch as: how high or how low a sound is; depends on the number of vibrations
      • We defined pitch as how high or low a sound is; depends on the number of vibrations
    • Experiment # 2
      • Experiment: to contrast high pitch and low pitch!
      • Materials:
      • You will need- 3 bottles, form a group of 3, water, recording sheet
      • Method: What you have to do-
      • 1) Fill in 100ml of water in first bottle
      • 2) Fill in 150ml in 2 nd bottle
      • 3) Fill in 200ml in 3 rd bottle
      • 4) Blow across the tops of the bottles (note the differences)
      • 5) Tap the bottles (what is the difference?)
