Mrs. Algier
Do Now: Write down 2-3 things that you want me to know about you

11. YWBAT Identify 5 traditional areas of study in Chemistry
Identify 4 steps in the Scientific Method
Identify the location and function of safety items in the classroom

12. The Central Science

13. Traditional Areas of Study in Chemistry
Organic Chemistry
Inorganic Chemistry
Biochemistry
Analytical Chemistry
Physical Chemistry

14. Organic Chemistry Study of chemicals that contain carbon
Examples include fuels, plastics, perfumes, pharmaceuticals

15. Inorganic Chemistry Study of chemicals that do not contain carbon
Examples include metals, minerals, electronics

16. Biochemistry
Study of processes that take place in living organisms. Examples include digestion and muscle contraction.

17. Analytical Chemistry
Study of the composition of matter

18. Physical Chemistry
Studies the mechanism, rate, and energy transfer that occurs when matter undergoes a change

19. Careers that use Chemistry
Research
Engineering
Medicine
Environmental
Manufacturing
Management
Teaching
Law
Safety

20. Activity – Part 2

21. Scientific Method
Logical, systematic approach to the solution of a scientific problem.

22. Scientific Method

Observation
Hypothesis
Experiment
Conclusion

23. Observation
Uses your senses
May lead to a question

24. Scientific Method Vocabulary
Hypothesis: proposed explanation for an observation Experiment: procedure used to test a hypothesis Independent Variable: variable that you change during an experiment Dependent Variable: variable that is observed during the experiment

25. Mythbusters

26. Scientific Method
Big Bang Theory

27. Testing Hypotheses
For the results of an experiment to be accepted, the experiment must produce the same result no matter how many times it is repeated, or by whom.
This is why scientitst are expected to publish a description of their procedures along with their results.

28. Testing Hypotheses
Sometimes the experiment a scientist must perform to test a hypothesis is difficult or impossible.
For example, atoms and molecules, which are some of the smallest units of matter, cannot be easily seen.
A model is a representation of an object or event.
Chemists use models to study chemical reactions and processes.

29. Developing Theories
Once a hypothesis meets the test of repeated experimentation, it may be raised to a higher level of ideas. It may become a theory.
A theory is a well-tested explanation for a broad set of observations.

30. Scientific Laws
Scientific Law – concise statement that summarizes the results of many observations and experiments.
