3. Section 1: Chemists use an internationally recognized system of units to communicate their findings.
Section 2: Scientists use scientific methods to systematically pose and test solutions to questions and assess the results of the tests.
Section 3: Measurements contain uncertainties that affect how a calculated result is presented.
Section 4: Graphs visually depict data, making it easier to see patterns and trends.
