Light & Matter
The path light travels in.
What is a straight line?
The phase of matter that moves about freely and has a lot of space between its particles.
What is a gas?
When hailstorms typically occur.
What is later in the day?
or
Spring, Summer, Fall months
The variable in an experiment that is being measured or observed.
What is the dependent Variable?
The average of a set of numbers.
What is mean?
When the brain receives multiple inputs, it will respond to this one.
What is the strongest signal?
Where the water droplets that form on the outside of a cup of cold water come from.
What is the air outside the cup?
Earth's temperature will do this as you move away from the surface and higher into the atmosphere.
What is decrease?
Anything that has mass and takes up space.
What is matter?
No matter can get in or out of the system.
What is a closed system?
When light shines on an object it will reflect, transmit, and/or be absorbed depending on this.
What is the object's material?
The smallest particle of water.
What is a molecule?
This will happen to a parcel of air that is cooler than the air surrounding it.
What is sink?
When molecules of water in liquid form go into gas form over time.
What is evaporation?
The tool used to measure air pressure.
What is a barometer?
Glass has these, which cause light to be refracted when trying to pass through it.
What are impurities?
A double-walled cup with a vacuum or air between the walls slows down or minimizes this because there are fewer or no particles to collide between the walls.
What is conduction? (conduction of energy)
Solid surfaces in the air that water vapor can stick to.
What are cloud condensation nuclei?
Representation we use for explaining a phenomenon.
What is a model?
When water is below this point, the molecules are moving slow enough to remain in liquid form.
When a light input is detected by sense receptors in our eyes, it is turned into a signal that travels along this nerve to the brain.
What is the optic nerve?
Particles with different amounts of thermal energy will always move in this direction.
What is hot to cold?
A mixture of different types of substances in gas form including water vapor.
What is air?
A measure of the average kinetic energy of the particles in a sample of matter.
What is temperature?
The amount of water vapor in the air in comparison to how much it can hold at a given temperature?
What is relative humidity?
