Light
When light hits an object and bounces in a new direction.
What is reflection?
Anything that has both volume and mass.
What is matter?
A property of matter that can be observed or measured without changing the identity of the matter such as color, odor, mass, and volume.
What is a physical property?
The variable that is directly changed or manipulated.
What is the independent variable?
The state of matter where atoms stick together, have definite volume, definite shape, and cannot be compressed.
What is a solid?
Any object that allows all light to travel through it.
What is transparent?
The space an object takes up.
What is volume?
The physical form in which a substance exists such as a solid, liquid, or gas.
What is a state of matter?
The variable that is measured to observe if the change had an effect.
What is the dependent variable?
The state of matter where particles are free to move around and take up as much space as the size of their container.
What is a gas?
Any object that allows no light to travel through it.
What is opaque?
The amount of matter in an object.
What is mass?
A property of matter that can only be tested by attempting to subject it to a chemical change and observing its reaction.
What is a chemical property?
The variables that must stay exactly the same each time an experiment is conducted.
What is a controlled variable?
or
What is a constant?
The phase change where an increase in temperature causes a solid to change into a liquid.
What is melting?
The process where light hits an object and is converted into thermal energy.
What is absorption?
The force of attraction between objects that is due to their masses and the distance between them.
What is gravity?
When one or more substances react and change into new substances with different properties.
What is a chemical change?
In order for an experiment to be meaningful, there must be exactly one of these variables.
What is the independent variable?
The state of matter where particles are free moving, still hold together and have definite volume, but not definite shape and cannot be compressed.
What is a liquid?
The process where light waves move apart from each other when passing from one medium into another.
What is refraction?
The tendency of all objects to resist any change in motion.
What is inertia?
The physical property of matter that describes the relationship between the mass of a substance and how much volume it occupies.
A variable that is unlikely to change unless acted upon by another variable.
What is a dependent variable?
This term describes the freedom of movement that allows both liquids and gases to take on the shape of their container.
What is a fluid?
