Vibrations cause all sounds. When something vibrates sound waves are sent through the air to our ears to hear. Without vibrations there would be no sounds.

Sound travels to our ears through sound waves. Once something vibrates sound waves travel through the air and our ears receive and process the sounds.

Creating sound is done by making vibrations. Plucking a stretched rubber band would cause the object to vibrate and sound waves would be created. We would hear a sound if we listen to the rubber band.

We can change the volume or pitch of something when we change the way it vibrates. Volume is how loud or soft something sounds and pitch is how high or low the sound is. By making something vibrate more or less, faster or slower, we can change the way it sounds.

Vibrations are quick back-and-forth movements that create sound waves that travel to our ears for us to hear. An example would be the vibrate setting on a cell phone or holding a ruler off a desk and flicking it so it bounces back and forth on the edge of the table.

The best set-up of an investigation to see how vibrating materials make sounds would be to use a tuning fork. Once the metal tuning fork is hit on the best students can visually see the fork vibrating and can move their ears closer to listen. Students will be able to see and hear how the vibrations work.

Put a plastic ruler at the edge of the table so half of it hangs over the edge. Observe the ruler. Hold the ruler down with the palm of one hand on the table. With your other hand push the end of the ruler down and let it go. Observe the ruler again.

This investigation demonstrates the difference between a still ruler (no movement or sound) versus a ruler that has been pushed and caused to vibrate (moves up and down, and there is a sound). When the ruler is still, there is no sound, when it begins to vibrate, a sound is heard. This shows that vibrations make sounds.

This picture demonstrates a drop of water rippling outwards in waves. A similar process happens with sound. Vibration causes a sound wave to be formed, and that sound wave moves outwards towards our ears so it can be processed into sound.

The player would bang the drumstick on the surface of the drum, which would cause a vibration of the air in the drum against the outer material. This would travel to our ears as a sound wave so we could hear the music being played.

Vibrating means small, quick back-and-forth movements. When you pluck a rubber band, it vibrates, when we talk our vocal cords vibrate, everything vibrates when it makes sounds.

Pat's class is given an empty metal can with plastic wrap stretched across the top secured with a rubber band. His teacher sprinkles salt on the top of the plastic wrap. He is given a tuning fork and told to strike it on the desk and touch it to the side of the can. The rice starts to jump and he hears a sound. Why is this happening?

The salt moved because of the vibrations of the tuning fork. When struck on the desk it begins vibrating which makes a quiet sound. When the tuning fork is placed against the can it gets louder because the can is also vibrating. This causes the rice to start "jumping" because it is also vibrating. Pat will hear the tuning fork, metal can, and the sound of the rice hitting the plastic wrap because of the vibrations.

This is a true statement. Vibrating materials do create sounds. If you think if the strings of a guitar, when strummed the strings vibrate and create the sounds. Sound comes from vibrations.

A drum produces sound when it is struck with a hand or object because the skin or outer covering vibrates. The air vibrates and sound waves move through the air producing the banging noises we hear with drums.

Students place their hands on the front of their throat. The teacher asks them to hum softly and write down what they feel. The teacher asks them to hum louder and write down what they feel. The teacher asks them to be silent and write down what they feel.
Why was there no humming sound when there was no vibration?

When materials (including our vocal cords) vibrate, a sound is produced. When the students hum, there is a vibration; when there is no sound, there is no vibration. For sound waves to be produced, the material has to vibrate.

Students are told to make sounds in class. They stomp their feet, whistle, clap, and snap their fingers.

All of these sounds have movement in common. Something is moving before or during the sound so cause it to happen. Vibrations from clapping or whistling create the sound waves that carry the noise we hear to our ears.

Place a ruler on the edge of a desk, so that eight inches of it hangs over the side. Place one hand on the four inches that remain on the desk to hold the ruler securely. With your other hand, whack the end of the ruler that is hanging off of the desk. The ruler will vibrate up and down.
