These are the two different types of waves we have discussed.
What are transverse and compression waves?
100
Energy that travels as transverse waves in a straight path/ ray.
What is light?
100
Sound travels best through this medium because the molecules are tightly packed.
What is a solid?
100
This is an observation made using your senses.
What is qualitative data?
100
This is the variable that is purposely changed by an experimenter.
What is the independent variable?
200
This is the lowest point on a transverse wave.
What is trough?
200
A thin beam of light moving in a straight path from its source
What is a ray?
200
This is the range of normal human hearing.
What is 20 Hz- 20,000 Hz?
200
This is an observation made with measuring instruments such as rulers, balances, thermometers, etc.
What is quantitative data?
200
This is the variable that responds or changes as a result of what the experimenter has manipulated.
What is the dependent variable?
300
This is the highest point on a transverse wave.
What is peak or crest?
300
Absorbed, reflected, transmitted, or refracted.
What are the four things that can happen to light after it leaves a source?
300
This is how high or low a sound is and is determined by the frequency of the wave.
What is pitch?
300
The insect was 3 centimeters long.
What is quantitative data?
300
This is the standard for comparison in an experiment, or the group that receives no change.
What is the control?
400
This is the part of a sound wave where the molecules are bunched closest together.
What is compression?
400
Red, orange, yellow, green, blue, violet
What is the visible spectrum?
400
This is the height of the wave and determines how loud or quiet a sound is heard.
What is amplitude?
400
The sun is bright.
What is qualitative data?
400
A student designs an experiment to test color absorption by placing ice cubes on both black and white papers in the sun. In this experiment, these were the location, the size and type of paper, the size of the ice cubes, and the time.
What are constants?
500
This is the number of wavelengths per second.
What is frequency?
500
A student shines a flashlight through a glass of water onto a mirror. Explain what happens to the light waves in the order it would happen and why. Use at least 4 vocabulary terms from our light flip book.
Refraction through the glass of water because it is a different medium and transparent, then reflected off the mirror because it is smooth and shiny and opaque.
500
You have three equal sized glass bottles, one nearly full of water, one halfway filled with water, and one with very little water in it. Which would produce the lowest pitched sound and why?
The one with the least water would make the lowest pitch because there is a longer column of air.
500
This is a conclusion reached on the basis of observation, evidence, and reasoning.
What is an inference?
500
An investigation was completed to see if keeping the lights on for different amounts of time each day affects the number of eggs that chickens laid. This was the number of eggs laid.
What is the dependent variable?
