Sound travel
How does sound travel?
through sound waves in the air
can you feel sound? Give an example
Yes, the paper cup telephone
Where did Jake and Sam go to learn about sound in our story, 3 cheers for ears?
the Science Museum
What was the invention that repelled kids? How did it repel the kids?
The Mosquito, repelled kids by making a high-pitched sound only kids can hear
What exists in the ocean other than water?
big sea animals, fish, trash :(, and SALT
can sound break glass?
Yes!
Can you see sound? Give an example
Yes, sprinkles on plastic wrap
What did Jake and Sam learn about at the Science Museum?
the reasons a person might not be able to hear
Why are some sounds high and some sounds low?
wavelength!
once salt dissolves, it looks like it completely vanishes. Is it actually still there?
yes
can sound travel underwater?
Yes
What is an oscilloscope?
a machine that reflects the shape of the sound waves
What is an eardrum?
A thin piece of skin that vibrates when sound waves hit it
What is a "wavelength"?
the distance between each wave's peak
Where is the Dead Sea located?
What would happen if you screamed in outer space?
No air, so no sound travel. You would not be heard.
How does an oscilloscope work? Use examples from the oscilloscope and bouncing sound websites
Sound waves are made as we speak and make noise. For the bouncing sounds, emojis/balls/numbers/etc. moves up and down like waves as we spoke and made noise
What happens when a sound wave hits the eardrum?
the eardrum vibrates
What is the difference between a high-pitched sound and a low-pitched sound?
high-pitched: have short wavelengths (peaks are close together)
low-pitched: have longer wavelengths (peaks are more spread out)
It is so salty that nothing can live in it
With an oscilloscope, sounds that are a max of pitches make messy waves. What was one of the sounds that made a simple wave
whistling
What happened to the oscilloscope waves when we made a sound louder or softer?
the waves changed frequency and height
As a person ages, special cells inside the ear called the hair cells start to die. What is an effect of this?
the person is unable to hear high-pitched sounds
Why did the Mosquito make a high-pitched sound?
the sound waves it creates move at a high frequency
The water that runs into the Great Salt Lake, like all lakes, is fresh. What causes the water to become so salty once it runs into the Great Salt Lake?
As the water runs over the ground, it touches rocks and soil. Some parts of the rocks and soil break up or dissolve in water. As this water flows into the Great Salt Lake, it brings in dissolved materials, such as salt. U
