In this section…. Scale of chemistry. Measuring matter. Pure matter on the macroscopic scale. The lab technician shown here is using a magnifying lens to examine a bacterial culture in a petri dish. When scientists cannot see the details of what they study, they try to obtain experimental data that help fill in the picture.. Development of the Atom. The Hellenic Market. Fire Water Earth Air. ~. ~. The Greeks. History of the Atom. Not the history of atom, but the idea of the atom . In 400 B.C the Greeks tried to understand matter (chemicals) and broke them down into earth, wind, fire, and water.. Science is based off of observations.. A Scientific Law is a summary of what is seen in observations. . A Scientific Theory is an explanation of why these observations are occurring.. Both laws and theories are tested by using them to predict what would happen in certain situations.. Scale, Scale Factor, & Scale Drawings. Objective:. 7.2.01 & 7.3.03. Essential Question:. .
