Scientific Inquiry
100
The topmost part of a wave.
Crest
100
What is the unit that frequency is measured?
Hertz
100
Describe a wave that has a low volume.
Short amplitude
100
What kind of waves do not need a medium.
EM waves
100
Sarah wanted to know which liquid (water, ketchup, sprite, or Pepsi) removes the most amount of rust from a nail. Identify the Independent and Dependent Variables.
IV: Type of liquid DV: Amount of rust removed
200
The bottom most part of a wave.
Trough
200
Define: Volume of a wave
The loudness or intensity of a sound.
200
Describe a wave that has a high pitch.
Wavelengths are short. High frequency.
200
Name the three kinds of mediums.
Solids, liquids, and gases
200
Sarah wanted to know which liquid (water, ketchup, sprite, or Pepsi) removes the most amount of rust from a nail. List three constants.
The amount of liquid, the amount of rust on a nail, the amount of time the nail is in the liquid, the method of rusting the nail, the method of removing the rust to measure it etc.
300
Define: Medium
A substance through which a waves moves
300
What kind of mechanical wave is a sound wave?
Longitudinal
300
Draw a wave that has a low volume and a low pitch.
Long wavelengths (low frequency) and short amplitude
300
Which medium would sound travel through faster through: Ground or Water. Why?
Ground, because sound travels fastest through solids
300
Sarah wanted to know which liquid (water, ketchup, sprite, or Pepsi) removes the most amount of rust from a nail. What is the control?
Water
400
Define: Resting point
The position a medium would take if there were no wave
400
Define: Pitch
The quality of highness or lowness of sound.
400
Draw a wave that has a high volume and a high pitch.
Short wavelengths (high frequency) and tall amplitude
400
Why does sound not travel in space?
Space is a vacuum. There is no matter for sound waves to travel through.
400
Sarah wanted to know which liquid (water, ketchup, sprite, or Pepsi) removes the most amount of rust from a nail. Provide an appropriate title for this experiment.
The Affect of Liquids on the Amount of Rust on a Nail. The Affect of Pepsi on the Amount of Rust on a Nail. (or any variation of this)
500
Define: Amplitude
The maximum distance that a disturbance causes a medium from its resting point.
500
Define: Frequency
The number of waves that pass a fixed point in a given amount of time.
500
Draw a wave that has a high volume and a low pitch.
Long wavelengths (low frequency) and tall amplitude
500
Rank in order of how sound travels through each medium starting with the slowest.
Solid, Liquid, Gas
500
Sarah wanted to know which liquid (water, ketchup, sprite, or Pepsi) removes the most amount of rust from a nail. Write a testable question for this scenario.
Which kind of liquid removes the most rust from a nail. Does ketchup or water remove more rust from a nail? (or any variation of that)
