1 CHAPTER 1 Introduction to Chemistry

2 Chemistry is…  The study of the composition of matter and the changes that matter undergoes

3 1. Organic Chemistry  Study of substances containing carbon  For example, petroleum based products, fuels, etc

4 2. Inorganic Chemistry  Study of substances that do not contain carbon  For example, rocks, precious metals, mining

5 3. Analytical Chemistry  Study of the composition of substances  For example, finding small quantities of medication in blood

6 4. Physical Chemistry  Study of the behavior of chemicals  For example, the stretching of nylon, bathing suits, chewing gum

7 5. Biochemistry  Study of the chemistry of living things  For example, the process of digestion and respiration

8 Applications of Chemistry:  Materials  Energy  Medicine and biotechnology  Agriculture  Environment  Astronomy

9 CHEMISTRY is ALL AROUND You… You just need to learn how to look for it!!!

10 The Scientific Method  O bservation (use your senses)  H ypothesis (proposed explanation for observation)  E xperiment (test the hypothesis)  C onclusion (what did you find?)  Reject or support hypothesis?  May need to revise hypothesis and re-experiment  Communicate O.H.E.C. Not AGAIN!!!

11 Laws and Theories  Theory = an idea that is widely supported by scientific experimentation  Can never be proven because it can always be challenged  Gives one the power to predict the behavior of natural systems  Law = concise statement that summarizes the results of many observations and experiments

12 Scientific Method Worksheet  Inference vs. observation  Qualitative vs. quantitative  Control vs variable

13 Chapter 1 EOC Questions  Page 25-27 # #16, 18, 22, 25, 29, 41 Mystery Cubes
