100
Logical interpretations of observations based on prior knowledge.
What are inferences?
100
A traveling disturbance that carries energy from one place to another.
What is a wave?
100
Sound travels fastest through this medium.
What is a solid?
100
Materials that fall into this category transmit light.
What is transparent?
100
A push or a pull.
What is a force?
200
Involves all of the five senses.
What is observation?
200
A wave that requires a medium to travel.
What is a mechanical wave?
200
Sound travels as this kind of wave.
What is a longitudinal wave?
200
Objects of this color absorb every color.
What is black?
200
This force on an object is the sum of all forces acting on it.
What is net force?
300
A testable explanation for an observation related to a scientific question.
What is a hypothesis?
300
The three parts of a longitudinal wave.
What are compressions, rarefactions, and wavelengths?
300
The speed of sound depends on these three characteristics of the medium it is traveling through.
What is elasticity, density, and temperature?
300
This acts as a lens, refracting light as it enters the eye.
What is a cornea?
300
This force pulls objects toward Earth.
What is gravity?
400
A well-tested idea that explains and connects a wide range of observations.
What is scientific theory?
400
The height of the wave and the maximum distance moved from the rest position.
What is amplitude?
400
This causes the particles of a wave to move faster (warm, cold)
What is warm?
400
The retina cells that respond to color.
What are cones?
400
Any force that causes objects to move in a circle.
What is centripetal force?
500
The one factor that a scientist changes during an experiment.
What is a manipulated variable?
500
The number of waves that pass a given point in a given amount of time.
What is frequency?
500
This part of the ear converts the sound waves into a form your brain can understand.
What is the inner ear?
500
Objects that cannot be passed through by light.
What is opaque?
500
Forces that are equal and are exerted in the opposite direction that have a net force of zero.
What are balanced forces?
