State the formulas to find the volume of a 6-sided 3D object and a cylinder.

Pi x radius squared x height
Distinguish the difference between a pure substance and a mixture.
A pure substance is an element or a compound.
A mixture is a combination of substances that occurs without any chemical reactions. The substances retain their properties and can be separated.
Describe Electromagnetic Radiation.
Waves of pure energy at any wavelength in the electromagnetic spectrum.
List the four fundamental forces found in nature.
Gravitational Force
Electromagnetic Force
Strong Nuclear Force
Weak Nuclear Force
Define the Law of Conservation of Energy.
The principle that energy cannot be created or destroyed, only changed from one form to another.
List the 3 Laws of Motion.
An object remains in its present state of motion -- either at rest, or moving at a constant speed in the same direction.
The acceleration of an object is proportional to the force of acting on it.
When one object pushes on one another with a certain force, the second object pushes back on the first one with equal force.

Define or state the difference between molecular and crystalline compounds.
Molecule is a chemically bonded cluster of atoms.
Crystal is a substance held together by ionic bonds, characterized by the orderly arrangement of atoms in a rigid lattice structure.
What are the 3 subatomic particles of an atom?
Netrons, Protons, and Electrons.
What are 3 of the 6 conditions necessary for life, and why are they essential?

Just the right distance from the sun so that earth doesn't burn or freeze.
Atmosphere to trap heat.
Large moon stabilizes the earth's axis.
Physical constants must have just the right values.
Magnetic field around the planet to shield us from. harmful solar wind.

What are the 3 Laws of Nature?
"There is NO reason" that nature exists.
"There is some underlying natural principle, that just happens to be part of nature, and compels things to be this way"
"The universe was intentionally and intelligently designed."
What is the formula for Mass-Energy Equivalence? What does each variable in the formula represent?
E=mc2
E = energy
m = mass
c = speed of light (300,000,000 meters per second)
What is the volume of a box that is 5 ft. long, 8 ft. wide and 2 ft. tall?
5 x 8 x 2 = 80 ft3
