How Loud
The term for how loud or soft the sound is.
What is volume?
Pitch is related to what word? Amplitude, Volume, or Frequency?
What is frequency?
Sound is made by ___________________.
What is vibrations?
When a sound wave is reflected off a hard surface or a large open area.
What is an echo?
In paper telephones, during what condition will sound not travel and why?
In paper telephones, sound will not travel in a string that is loose. The vibrations can not travel down the string and get lost in the air.
Volume is related to what word?
What is amplitude?
The faster the waves, the higher the frequency, the __________ the pitch.
What is higher?
Why does sound not travel in outer space?
What is in outer space, there is no air particles in a vaccuum so the sound can't vibrate.
In the nail lab when I placed three nails of different length on a sponge, which nail produced the highest pitch? Small, Medium, or Large nail? Why?
What is the nail with the shorter length because it had faster vibrations?
Longer, Thicker, and Wider objects produce _______________ pitches. (Higher or Lower)
What is lower?
Object like carpet, foam, and a small area will ______________ sound. What type of objects are these?
What is absorb sound? What is soft objects?
In a sound wave, what travels in the wave?
Which is the right answer? Energy, Frequency, Matter, or Particles?
What is energy?
What state of matter does sound move the fastest through and why?
What is a solid because the molecules are close together and sound can vibrate them quicker and move sound throughout?
What is it when animals or humans like Ben Underwood reflect sound off objects in the environment to give them an idea of where they are located once the sound bounces back? Give me one animal that does this.
What is echolocation? What is dolphins, whales, and bats?
Shorter, Thinner, Smaller, and tighter strings produce _________________ pitches. (Higher/Lower)
What is higher?
Objects like concrete, wood, and large open area will ____________ sound. What type of objects are these?
What is reflect? What is hard objects?
Why do dogs hear dog whistles but humans do not?
What is the sound of the dog whistle is outside of the human frequency range of 20 to 20,000 hertz to hear things?
Sound moves out from a source like a slinky would. When the air molecules are squeezed together or the slinky pieces are close together, we say the sound wave is a ____________________ wave.
What is compression?
What is the science term of the material that scientists call that allows sound to move through it?
What is medium?
I have a bell. I start to ring it. The people near me start to hear it....a few seconds later, the people further away start to hear it. What is happening to sound? How does sound move out?
What is sound moves out in all directions from the source of the bell?
A high amplitude is a loud or soft sound?
What is a loud sound because amplitude is the amount of energy compared to a normal sound wave?
If a sound is high pitched and soft, the sound wave is _________ frequency and _______ amplitude.
What is high frequency and low amplitude?
What two things could you do to change the pitch of a stringed instrument?
What is tighten or loosen the strings, change the length of the strings, and change the width of the strings making some strings thicker or thinner?
When we blew into the bottles, explain the bottle that gave me the highest pitch and which bottle that gave me the lowest pitch?
What is the bottle with the most water gave us a higher pitch because there was less space to vibrate producing high frequency waves. The bottle with the less water gave us a low pitch because there was more space to vibrate producing low frequency waves.
How does sound travel to your brain so you can hear it? Must have 3 of the ones below to have the answer correct.
What is the air molecules are vibrating, the molecules create a sound wave, the sound wave moves through the ear canal, the vibrations hit the ear drum, the drum hits 3 small bones, the vibrations move to the cochlea that moves tiny hairs sending impulses through the nerves to the brain.
