1st Grade Science › Sound and Vibration
What does it mean if something vibrates?
It moves quickly back-and-forth
It moves slowly one time
It is a type of dance move
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.

Which investigation provides evidence relating to sound and vibrations?
Investigation 1: Jack hits a tuning fork on a desk and watches it move back and forth and hears a noise when he moves close. Jack observes a still tuning fork and hears nothing.
Investigation 2: Amber feels rumbling and hears growling in her stomach so she eats mac and cheese for lunch.
Investigation 1
Investigation 2
Neither investigation
Investigation 1 provides evidence that there is a relationship between sound and vibrations. The tuning fork is moving back and forth (vibrating) and a sound was made. Jack is able to see the vibrations and then hear a notice when he makes his observations. This shows a link between sound and vibration.
Vibrating materials make a sound. What can we change about a sound by making it vibrate differently?
The volume and pitch.
How good or bad it sounds.
The sound cannot be changed.
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.

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?
Vibrating materials (like the fork and can) make sounds and cause other vibrations.
The tuning fork is magic so it allows the rice to move and make sounds.
There is no relationship between the vibrations and sound.
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.
How does sound travel to our ears?
Sound waves
Ocean waves
A waving hand
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.
Which investigation does NOT provide evidence relating to sound and vibrations?
Investigation 1: Austin plays a song in the talent show with a guitar he's made. He put four rubber bands over the opening of an empty tissue box and plucks them. When they move it makes music.
Investigation 2: Kim treats her friends poorly and says mean things to them in the science lab. She was trying to hit them with the ruler and snap them with rubber bands. They asked her to stop.
Investigation 2
Investigation 1
Neither investigation
Investigation 2 does not provide evidence to sound and vibrations. There is a sound that takes place when the students ask Kim to stop or when she is saying mean things, but there is no evidence of vibrations that we can see. Investigation 1 includes information about the rubber bands moving when plucked and that this creates music. This investigation does provide proof of sound and vibrations being related.
