Explanation:

• Matching:
• A theory is a logical explanation for events, so 1 - D.
• Data is information often organized in graphs and charts, so 2 - G.
• Newton is a famous scientist who contributed to the scientific method, so 3 - F.
• A law is an accepted theory that was tested many times, so 4 - B.
• A hypothesis is an educated guess, so 5 - I.
• A variable is a factor being tested, so 6 - A.
• A control has everything set up the same, but missing the variable, so 7 - C.
• Observe is the first step of the scientific method, so 8 - J.
• Conclusion is the last step of the scientific method, so 9 - E.
• Experiment is the testing of a hypothesis, so 10 - H.
• Multiple - Choice:
• The main purpose of the scientific method is to determine answers to scientific questions, so 11 - B.
• A theory mainly becomes a law when it is approved by the scientific community, so 12 - B.
• The main purpose of the passage is to inform the reader of what the scientific experiment is and its steps, so 13 - D.
• In the quote, "vital" means important, so 14 - A.
