200
Data that is based on characteristics or traits
What is qualitative data
200

200
What does a wave transfer?
What is energy
200
What is the job of the hammer, anvil, and stirrup?
What is to carry vibrations to the inner ear.
200
Measured from the resting point of a wave up to a crest or down to a trough - measures how much energy is in a wave
What is amplitude
300
An educated guess or prediction that can be tested
What is a hypothesis
300
What metric unit would you use to measure the length of a strand of spaghetti?
mm - cm - m - km
What is cm
300
Define: frequency
What is the number of waves passing a fixed point in a certain amount of time
300
What transmits vibrations from the eardrum to the inner ear?
What is the hammer, anvil, and stirrup
300
Define: transverse wave
What is a wave where the disturbance moves perpendicularly to the direction of the wave
400
A test performed to find out whether a hypothesis is right or wrong
What is an experiment
400

1000 - 100 - 10 - 1 - .1 - .01 - .001
km - hm - dcm - m - dm - cm - mm

What is a wave that the disturbance moves in the same direction as the wave does.
400
Describe how human sound is produced (steps)
What is
1) air being pushed from the lungs through the opening between the vocal cords
2) force of the air causes the vocal cords to vibrate
3) vibrations cause sound waves
400
Does sound travel outside Earth's atmosphere in space? Explain.
No, it does not because space doesn't have matter. A sound wave needs a medium (matter) to move through
500
Correctly put the steps of the scientific method in order
What is: 1) Question Problem, 2) Hypothesis 3) Experiment, 4) Record/Collect Data, 5) Conclusion
500
What is a meniscus? How does someone read a meniscus?
What is the "U" shaped curve in a graduated cylinder. You read it by getting eye-level with the graduated cylinder and reading the bottom of the curve.
500
Define refraction
What is bending of a wave as it enters a new medium (different angle)
500
Explain why sound travels faster through iron than through air.
Sound waves move faster through a solid than a gas because the particles are able to move faster.
500
Define: diffraction
What is spreading out of wave through an opening or around an obstacle.
