  1. CH104 • CHEMISTRY • FOR • ALLIED HEALTH • CHEMEKETA COMMUNITY COLLEGE • INSTRUCTOR: Dr. Jan Cammack • http://faculty.chemeketa.edu/jcammack/

  2. 1st Day Stuff • Who are you? Are you in the right place? • GOB • Chemeketa elearn site • Course Web Page • Course Syllabus & requirements • Who am I? • Web CT Quizzes

  3. CH104 Recitation & Lab: Week 1 • Read through • Lab 1A: Safety and • Lab Experiment 1B: The Scientific Method • Homework problems due each day • Online quiz due Tuesday

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

  5. Definition of Chemistry • Chemistry is the study of substances in terms of • Composition What is it made of? • Structure How is it put together? • Properties What characteristics does it have? • Reactions How does it behave with other substances?

  6. Major divisions of Chemistry Elements besides Carbon Methods of analysis Theory and concepts Carbon based compounds Chemistry of living things • General • Inorganic • Analytical • Physical • Organic • Biochemistry

  7. Chemistry in Our Lives Scientific Method:Thinking like a Scientist

  8. The Scientific Method • Process used by scientists to explain observations. It involves • making observations • writing a hypothesis • doing experiments • proposing a theory

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

  10. Summary of the Scientific Method

  11. Everyday Scientific Thinking The sound from a CD in a CD player skips. Observation: The CD player is faulty. Hypothesis 1: 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.

  12. Learning Check The step of scientific method indicated in the processes below is • 1) observation2) hypothesis • 3) experiment4) theory • A. A blender does not work when plugged in. • B. The blender motor is broken. • C. The plug has malfunctioned. • D. The blender does not work when plugged into a different outlet. • E. The blender needs repair.

  13. Solution The step of scientific method indicated in the processes below is • 1) observation2) hypothesis • 3) experiment4) theory • A. A blender does not work when plugged in. 1 • B. The blender motor is broken. 2 • C. The plug has malfunctioned. 2 • D. The blender does not work when plugged into a different outlet. 3 • E. The blender needs repair. 4

  14. Chemistry in Our Lives A Study Plan for Learning Chemistry

  15. Text Features for Learning • The study features in the text include: • Learning Goals • indicate what to learn • Concept Checks • develop new concepts • Sample Problems • provide step-by-step problem solving models • Guides to Problem Solving • give directions for working out a problem

  16. Studying for Chemistry 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

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

  18. Learning Check 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

  19. Solution 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
