1.
Analytical Chemistry: Is the area of study that focuses on the composition of matter. (A task that would fall into this area of chemistry is measuring the level of lead in drinking water.)
2.
Applied Chemistry: Is research that is directed toward a practical goal or application. (In practice, pure chemistry and applied chemistry are often linked. Pure research can lead directly to an application, but an application can exist before research is done to explain how it works.)
3.
Biochemistry: The study of processes that take place in organisms. (These processes include muscle contraction and digestion.)
4.
Biotechnology: Applies science to the production of biological products or processes.
5.
Chemistry: Is the study of the composition of matter and the changes that matter undergoes. (Because living and nonliving things are made of matter, chemistry affects all aspects of life and most natural events.)
6.
Experiment: A procedure that is used to test a hypothesis.
7.
Hypothesis: Is a proposed explanation for an observation.
8.
Inorganic Chemistry: Is the study of chemicals that, in general, do not contain carbon. (Inorganic chemicals are found mainly in non-living things, such as rocks.)
9.
Macroscopic: The world of objects that are large enough to see with the unaided eye.
10.
Manipulated variable: The variable that you change during an experiment. (Also known as an independent variable.)
11.
Matter: Is anything that has mass and occupies space.
12.
Microscopic: The world of objects that can be seen only under magnification.
13.
Organic Chemistry: Is defined as the study of all chemicals containing carbon.
14.
Physical Chemistry: Is the area that deals with the mechanism, the rate, and the energy transfer that occurs when matter undergoes a change.
15.
Pollutant: Is a material found in air, water, or soil that is harmful to humans or other organisms. (Chemists help to identify pollutants and prevent pollution.)
16.
Pure Chemistry: Is the pursuit of chemical knowledge for its own sake.
17.
Responding variable: The variable that is observed during the experiment. (Also known as a dependent variable.)
18.
Scientific Law: Is a concise statement that summarizes the results of many observations and experiments.
19.
Technology: Is the means by which a society provides its members with those things needed and desired.
20.
The Scientific Method: Is a logical, systematic approach to the solution of a scientific problem. (Steps in the scientific method include: Making observations, testing hypotheses, and developing theories.)
21.
The steps for solving a conceptual problem:: Analyze and solve.
22.
The steps for solving a numeric word problem:: Analyze, calculate, and evaluate.
23.
Theory: Is a well-tested explanation for a broad set of observations.
