How is sound produced?
By vibrations
How does heat transfer?
From the warmer object to the colder object.
What is position?
A place where something is located.
When you compare data, what MUST BE THE SAME??

To determine speed, what TWO things do you need to measure?
Time and distance
What other form of energy is tied to sound energy?
Energy of motion. (mechanical energy)
What is a conductor?
A material that allows heat to move through it easily.
What is direction?
The way something is facing or a way in which something has moved.
What is an observation?
something that has been seen, heard or noticed. just stating a fact.
When using a ramp, what data is needed to determine speed?
The HEIGHT of the ramp.
How is a high pitch made?
vibrations are quick because sound waves are closer together.

Describe the marshmallow flyer's direction if it hit the ceiling then fell back to the floor.
It's direction went UP then STRAIGHT DOWN.
When comparing speeds, what must be the same?
Same units were used to measure distance traveled
Same unit of time was used to measure how long it took.
How is low pitch made?
vibrations are slower because sound waves are farther apart.
What would cause a metal habitat to be warmer than the others?
The metal walls conducted more heat
If something moved while you weren't watching, how would you be able to tell it had been in motion?
It might have a new position or direction.
