Life Cycle
The series of stages in form and functional activity through which an organism passes between successive recurrences of a primary stage.
An electromagnetic radiation in the wavelength range including infrared, visible, ultraviolet and x-ray and traveling in a vacuum with a speed of about 186,281 miles (300,000 kilometers) per second; specifically the part of this range that is visible to the human eye.
A fluid (such as water) that has no independent shape but has a definite volume and does not expand indefinitely and that is slightly compressible.
A device with fixed and moving parts that modifies mechanical energy in order to do work.
A class of physical phenomena that include the attraction for iron observed in lodestone and a magnet, are inseperably associated with moving electricity, are exhibited by both magnets and electric currents, and are characterized by fields of force.
The process of making a raw material into a finished product; especially in large quantities.
The tangible substance (chemical, biological, or mixed) that goes into the makeup of a physical object. One of the basic resources used in a technological system.

Natural Material
Material found in nature, such as wood, stone, gases and clay.
A path described by one body in its revolution about another (as by the earth about the sun or by an electron about a nucleus).
