General ChemistryPeople often have a very narrow view of chemicals, thinking of them only as dangerous poisons or pollutants.Compose Ordinary Things There is nothing you can hold or touch that is not made of chemicals. Chemicals make up virtually everything we come into contact with.Knowledge as a Result of the Senses:• Observations involve measuring or observing some aspect of nature. • Hypotheses are tentative interpretations of the observations. • Laws summarize the results of a large number of observations. • Theories are models that explain and give the underlying causes for observations and laws.Scientific MethodScientific MethodOne or more well-established hypotheses may form the basis for a scientific theory.A number of similar observations lead to
