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