5th grade topic 1 question
5th Grade Topic 1 Question
  • If Mrs. B was plucking a string on her guitar and she wanted to create a higher pitch sound, what would she need to do to the string?
5th grade topic 1 answer
5th Grade Topic 1 Answer
  • Mrs. B would need to tighten the string on the guitar by turning the tuning key. Once Mrs. B tightened the string, the string would create a higher pitch.


5th grade topic 2 question
5th Grade Topic 2 Question
  • Define wavelength. How do we measure it?
5th grade topic 2 answer
5th Grade Topic 2 Answer
  • Wavelength measures the actual length of a wave. We measure wavelength by looking at the distance from either crest to crest or trough to trough.


4th grade topic 3 question
4th Grade Topic 3 Question
  • Which pitch has the slowest vibration and the lowest frequency? A low, medium, or high pitch?
4th grade topic 3 answer
4th Grade Topic 3 Answer
  • A low pitch has the slowest vibration and the lowest frequency.


4th grade topic 4 question
4th Grade Topic 4 Question
  • How does sound travel? Describe where sound starts and how it travels to its ending point.
4th grade topic 4 answer
4th Grade Topic 4 Answer
  • Sound starts at a sound source, and travels though a medium (solid, liquid, or gas) and into our ear. The sound then bounces off of our eardrum, and then the nerves in our ear transport the sound to our brain, which then processes the sound.


3rd grade topic 5 question
3rd Grade Topic 5 Question
  • How is sound made?
3rd grade topic 5 answer
3rd Grade Topic 5 Answer
  • Sound is made when an object or material vibrates.


3rd grade topic 6 question
3rd Grade Topic 6 Question
  • What is amplitude? How do we measure amplitude on a sound wave?
3rd grade topic 6 answer
3rd Grade Topic 6 Answer
  • Amplitude measures the intensity of a sound.
  • We can determine a sound waves amplitude by looking at the height of the wave. The higher the amplitude, the louder the sound, and vice versa.


2nd grade topic 7 question
2nd Grade Topic 7 Question
  • If Daniel had a thin rubber band and Emma had a thick rubber band and both of them plucked their rubber bands, what would the difference be in sound?
2nd grade topic 7 answer
2nd Grade Topic 7 Answer
  • Daniel’s thin rubber band would create a higher pitched sound. (Faster vibrations.)
  • Emma’s thicker rubber band would create a lower pitched sound. (Slower vibrations.)


2nd grade topic 8 question
2nd Grade Topic 8 Question
  • Where are the crest and the trough located on a wave?
2nd grade topic 8 answer
2nd Grade Topic 8 Answer
  • The crests are located at the high points of a wave, and the troughs are located at the low points of the wave.


1st grade topic 9 answer
1st Grade Topic 9 Answer
  • Pitch is how high or low a sound is. A flute would be an example of an instrument that creates a high pitch sound, and a tuba would be an example of an instrument that creates a low pitch sound.


1st grade topic 10 question
1st Grade Topic 10 Question
  • What is frequency? How do you create high frequency? How do you create low frequency?
1st grade topic 10 answer
1st Grade Topic 10 Answer
  • Frequency is the speed at which something vibrates(or the number of vibrations per unit of time).
  • To create a high frequency, one would need fast vibrations (and we would see many crests and troughs).
  • To create a low frequency, one would need slow vibrations (and we would see fewer crests and troughs).


1 000 000 question
1,000,000 Question
  • Explain the difference between pitch and volume. Support your explanation by giving examples!
1 000 000 answer
1,000,000 Answer
  • Pitch is how high or low a sound is. Volume is how loud or soft a sound is. Some high pitch sounds can both be loud and soft. For example, both a kittens’ meow and a fire trucks’ siren have high pitches, but a kitten projects a soft volume, while a fire truck projects a loud volume. The same goes for sounds that have low pitches, too!
