4.  What is Chemistry  The Scientific Method  How To Study

5.  Chemistry is the study of substances in terms of Composition What is it made of? StructureHow is it put together? Properties What characteristics does it have? ReactionsHow does it behave with other substances? 5

7. Scientific Method: Thinking like a Scientist

8.  Process used by scientists to explain observations. It involves  making observations  writing a hypothesis  doing experiments  proposing a theory

9. Observe: Observe: Take notice Hypothesize Hypothesize:Form an educated guess to explain your observation. Test Test the guess: Design an experiment. Reject or confirm the hypothesis Modify Modify the guess or test if needed. Conclude (Propose a Theory) Conclude (Propose a Theory):

10. Develop a theory Experiment Do more experiments Question Hypothesis Try new tests Did it work? Yes Observe No

12. Observation: The sound from a CD in a CD player skips. Hypothesis 1: The CD player is faulty. Experiment 1: When the CD is replaced with another one, the sound from the 2nd CD is OK. Hypothesis 2: The original CD has a defect. Experiment 2: When I play the CD in another player, the sound still skips. Theory: My experimental results indicate that the original CD has a defect.

15. A Study Plan for Learning Chemistry

16.  The study features in the text include: 1. Learning Goals indicate what to learn 2. Concept Checks develop new concepts 3. Sample Problems provide step-by-step problem solving models 4. Guides to Problem Solving give directions for working out a problem

17. Activities that can help you learn chemistry successfully include the following:  attend class regularly  go to your instructor’s office hours  form a study group with other students to discuss problems and their solutions  study and work problems every day  do not wait until the night before the test to prepare for an exam

18.  Active participation will help learn the material more quickly and with more understanding. 1. Obtain an overview from the Looking Ahead topics. 2. Form a question from the section title. 3. Read the section, and answer your question. 4. Work the Sample Problems and Study Checks. 5. Check Answers at the end of the chapter. 6. Proceed to the next section in the text and repeat above.

19. Which of the following activities would be part of a successful study plan? A. staying out late the night before an exam B. reading the text before class C. working problems with a study group D. skipping the lecture 1 or 2 times a week E. discussing a problem with the instructor

20. Which of the following activities would be part of a successful study plan? A. (No) staying out late the night before an exam B. (Yes) reading the text before class C. (Yes) working problems with a study group D. (No) skipping lecture 1 or 2 times a week E. (Yes) discussing a problem with the instructor
