6. Initial Questions Listen to this sound: Describe the sound. Record your answers on the Sound worksheet. Sound worksheetSound worksheet

7. What Sounds do You Hear? Think – Pair - Share Think Think about what sounds you hear everyday. Pair Pair up with a partner and share what you know. Record your answers on the Sounds We Hear worksheet.Sounds We Hear worksheet. Share Share with the class.

8. Sounds We Hear (Class share results) School Sounds Outside Sounds Night Sounds Street Sounds Kitchen Sounds

9. Whole Group Activity Tap your pencil lightly on your desk. What is the pencil doing when you hear the sound? What caused the sound you heard when you tapped your pencil against the desk? (the vibration of the pencil against the desk) Was the sound high or low? (The highness or lowness of a sound is the pitch.) What are some examples of sounds that are high, low; loud, quiet; harsh, pleasant; emergency?

10. High or low Pitch? Dolphin whistles: http://www.dolphinear.com/de-sound.htm Car horn: http://www.autospeak.com/library.htm Cow: http://www.angelfire.com/az/moocows/images/cows2.au Bell:

11. Let’s graph our results:

12. Small Group Experiment MYSTERIOUS MAGIC INTRODUCTION Let's start our investigation of sound by making some salt move without touching it. Is it a mystery? Is it magic? Or is it science? WHAT YOU NEED 1 rubber band 1 piece of plastic 1 large can 1 wood ruler 1 small can salt

13. What to do: (record results on your worksheet) your worksheetyour worksheet 1. Find a place to work that is not too close to another team. 2. Pull the plastic tightly over the open end of the large can and hold it while your partner puts the rubber band over it. 3. Sprinkle some salt on top of the plastic. 4. Hold the small can close to the salt and tap the side of the small can with the ruler. What happens to the salt? _______________________________________________________________________________________________________________________________ 5. Try tapping the small can in different spots or holding it in different directions. Find out how you must hold and tap the can to get the salt to move the most. ______________________________________________________________________________________________________________________
