What is Gravitation potential energy.
100
Waves carry this from place to place, not this.

The variable found on the y-axis of a graph
What is the dependent variable.
200
This type of energy is dependent upon its mass and position.
What is potential energy.
200
If the amplitude of a wave increases, its energy does this.
What is increases.
200
The strength of the pull of gravity on an object.
What is weight.
200

What are the signs of a chemical change.
300
My plant has grown 3 inches this week is this type of data.
What is quantitative data.
300
This law states that energy cannot be created or destroyed, only change forms.
What is the law of conservation of energy.
300
The distance from crest to crest.
What is a wavelength.
300

500
Data you collect using your 5 senses.
What is qualatative data
500
A book falls from a shelf; as it gets closer to the ground its kinetic energy does this.
What is increases.
