100
Objectively perceiving something via any of the five senses.
What is observing?
100
A solid, liquid, or gas that mechanical waves require in order to travel.
What is a medium?
100
The electromagnetic waves immediately preceding visible light on the spectrum.
What are infrared waves?
100
A reference point.
What is needed to determine whether an object is in motion?
100
The category of waves under which sound waves fall. (categorized by how it travels)
What are longitudinal waves?
200
The universal, consistent system used by scientists worldwide.
What is the metric system?
200
Crest, trough, wavelength, and amplitude.
What are the parts of a transverse wave?
200
High-energy, high-frequency waves on the higher end of the spectrum. Can cause cancer.
What are ultraviolet rays, X-rays, or gamma rays? (Any of the answers are acceptable.)
200
Distance traveled in a given direction by a moving object over a period of time.
What is velocity?
200
Any force that causes an object to move in a circular motion.
What is a centripetal force?
300
No personal pronouns, not written as a question, and a testable statement.
How must a hypothesis be written?
300
When a wave passes a barrier or moves through a hole in a barrier and consequently bends and spreads out.
What is diffraction?
300
The scattering of light occurs. (Hint: when they strike a specific type of material)
What occurs when visible light rays strike translucent material?
300
Calculating the net force of forces exerted in OPPOSITE directions.
When does one subtract?
300
The absence of reflected color.
What is blackness?
400
The metric tool used to measure mass.
What is a triple beam balance?
400
The quotient of speed and wavelength.
What is frequency?
400
The part of the eye that bends light as it enters.
What is the cornea?
400
An object that is thrown.
What is a projectile?
400

500
The SI unit of length spanning approximately 10 soccer fields.
What is a kilometer?
500
345 m/s (660 mph) at 21°C (room temperature).
What is the speed of sound?
500

What law states that gravity acts among all objects in the universe?
500
