Physics3a experiments sound: Detailed experiments on sound waves for middle school

  1. 1. PHYSICS 3a SOUND Experiments
  2. 2. <ul><li>Procedure: </li></ul><ul><li>Define the vocabulary found under Experiment 1. </li></ul><ul><li>Pull the string taught by having one person hold the cup and another person hold the other cup. </li></ul><ul><li>With the string taut (lots of tension), speak quietly or whisper a message to the other person into the cup. </li></ul><ul><li>Record observations in the Physics Journal. </li></ul><ul><li>Answer Questions & write up the Conclusion in the Physics Journal. </li></ul>SOUND Experiment 1: Telephone Materials : Physics 2 packet, Science notebook, pencil pre-made ‘telephone’: 10-20 ft length of string, each end fastened to the bottom of a cup (poked through)
  3. 3. <ul><li>Procedure: </li></ul><ul><li>Define the vocabulary found under Experiment 2. </li></ul><ul><li>TASK 1: Tap the table lightly with you finger. Do you hear it? Tap the table the same way with your ear on the table. Do you hear it? </li></ul><ul><li>TASK 2: Tap the balloon. Do you hear it? Tap the balloon with your ear against it. Do you hear it? </li></ul><ul><li>TASK 3: Stand with one person on one side of the door and the rest of the group on the other side of the door. The alone person on the other side says something like “Can you hear me?” in a moderately low voice. Standing a foot from the door, can the rest of the group hear this from the other side of the closed door? (Try a lower voice if you can.) </li></ul><ul><li>Try it again. This time the rest of the group uses a cup opened up against the closed door, ears against the bottom of the cup. Can you hear it now? Rotate so that the person on the other side gets a chance to listen as well. </li></ul><ul><li>Record observations in the Physics Journal. </li></ul><ul><li>Answer Questions & write up the Conclusion in the Physics Journal. </li></ul>SOUND Experiment 2: Traveling Sound Materials : Physics 2 packet, Science notebook, pencil blown & tied balloon, table, door, cups
  4. 4. <ul><li>Procedure: </li></ul><ul><li>Define the vocabulary found under Experiment 3. </li></ul><ul><li>Setup: Line up 8 bottles. Fill the first glass ¼ full. Fill the next one up slightly higher than the first one. Continue until you have filled up the last bottle. </li></ul><ul><li>GENTLY blow across the top of the bottle. Observe the difference in sounds. </li></ul><ul><li>Record observations in the Physics Journal. </li></ul><ul><li>Answer Questions & write up the Conclusion in the Physics Journal. </li></ul>SOUND Experiment 3: Bottle Music Materials : Physics 2 packet, Science notebook, pencil 8 bottles, water
  5. 5. <ul><li>Procedure: </li></ul><ul><li>Define the vocabulary found under Experiment 4. </li></ul><ul><li>TASK 1: Pluck the different rubber bands & observe how the widths & tautness affect the pitches. </li></ul><ul><li>TASK 2: Observe the simulation of ‘male’ vocal chords and ‘female vocal chords. How do they differ? How does this affect the sounds? </li></ul><ul><li>Record observations in the Physics Journal. </li></ul><ul><li>Answer Questions & write up the Conclusion in the Physics Journal. </li></ul>SOUND Experiment 4: Rubber band Band Materials : Physics 2 packet, Science notebook, pencil stretched rubber band between nails, variety of sizes; ‘male’ vocal chord simulation, ‘female’ vocal chord simulation
  6. 6. <ul><li>Procedure: </li></ul><ul><li>Work on Physics Journal. </li></ul><ul><li>Complete any questions/definitions not finished. </li></ul><ul><li>Complete SOUND Worksheets found in the Journal. </li></ul>SOUND Experiment 5: Physics Journal Materials : Physics 2 packet, Science notebook, pencil
  7. 7. <ul><li>Procedure: </li></ul><ul><li>Work with a partner in your group. One person fill the film canister with a small object, without the partner looking. </li></ul><ul><li>The other person shakes the canister and tries to use sound clues such as pitch, vibration, & interference to guess what is in the canister. Guess? (What did the person guess? Was it right?) </li></ul><ul><li>Switch jobs. </li></ul><ul><li>Repeat several times. </li></ul><ul><li>Record observations in the Physics Journal. </li></ul><ul><li>Answer Questions & write up the Conclusion in the Physics Journal. </li></ul>SOUND Experiment 6: Sound Shakers Materials : Physics 2 packet, Science notebook, pencil
  8. 8. <ul><li>Procedure: </li></ul><ul><li>Define the vocabulary found under Experiment 3. </li></ul><ul><li>Setup: Line up 8 glasses. Fill the first glass ¼ full. Fill the next one up slightly higher than the first one. Continue until you have filled up the last glass. </li></ul><ul><li>2. GENTLY tap each glass. Observe the difference in sounds. </li></ul><ul><li>2. Record observations in the Physics Journal. </li></ul><ul><li>3. Answer Questions & write up the Conclusion in the Physics Journal. </li></ul>SOUND Experiment 7: Bottle Music Materials : Physics 2 packet, Science notebook, pencil 8 glasses, metal striker, water
  9. 9. <ul><li>Procedure: </li></ul><ul><li>Cut circle out of wax paper bigger than circle of toilet roll. </li></ul><ul><li>Tightly fix the wax paper onto the end of the toilet roll with a rubber band. </li></ul><ul><li>Use your pencil to make a small hole (size of a dot) in the toilet paper roll 1 inch below the rubber band. (Make sure the wax paper is cut away from this spot. </li></ul><ul><li>Blow/Sing into the open end of the Kazoo. </li></ul><ul><li>What kind of sound is made? Can your group sing the ABC song? What about another song? </li></ul><ul><li>Take turns singing a song, having teammates guess the tune. </li></ul><ul><li>Record observations in the Physics Journal. </li></ul><ul><li>Answer Questions & write up the Conclusion in the Physics Journal. </li></ul>SOUND Experiment 8: Kazoo Materials : Physics 2 packet, Science notebook, pencil empty paper towel or TP roll, rubber band, wax paper
  10. 10. <ul><li>TASK 1 </li></ul><ul><li>Tap the tuning fork with the rubber mallet. What do you see? </li></ul><ul><li>Stop the vibration with your hand around the tines. </li></ul><ul><li>Strike again & gently touch it to the tip of your nose. What do you feel? </li></ul><ul><li>Strike again & gently touch the handle to the table. Put your ear down to the table. What do you hear? What do you feel? </li></ul><ul><li>TASK 2 </li></ul><ul><li>Tape aluminum foil ball to the side of the table so that it is suspended. </li></ul><ul><li>Strike the tuning fork. </li></ul><ul><li>Hold the tuning fork so that it barely touches the suspended ball. Describe observations. </li></ul>SOUND Experiment 9: Tuning Fork Materials : Physics 2 packet, Science notebook, pencil tuning fork, rubber mallet, rice, ping-pong ball, aluminum foil, paper plate, container ½ full of water, small length of string, tape, ruler <ul><li>TASK 3 </li></ul><ul><li>Strike the tuning fork & lower it (tines-down) into the container of water. </li></ul><ul><li>Repeat with another tuning fork. Describe observations. </li></ul><ul><li>TASK 4 </li></ul><ul><li>Pour rice onto the plate. </li></ul><ul><li>Strike the tuning fork & place tines on the rice. Describe observations. </li></ul><ul><li>TASK 5 </li></ul><ul><li>CLEAN UP!!! </li></ul><ul><li>Make sure that all of the materials are put up as they were when you came into the room. </li></ul>RULES: To strike a tuning fork 1. ALWAYS strike gently with a RUBBER mallet. 2. NEVER strike against glass or your eyes.
  11. 11. <ul><li>Procedure: </li></ul><ul><li>Work on Physics Journal. </li></ul><ul><li>Complete any questions/definitions not finished. </li></ul><ul><li>Complete SOUND Worksheets found in the Journal. </li></ul>SOUND Experiment 10: Physics Journal Materials : Physics 2 packet, Science notebook, pencil
