  1. Why Study Chemistry?

  2. Why Study Chemistry? • Everywhere

  3. Why Study Chemistry? • To see the glory of God • Where did I come from? • Why am I here? • Where am I going?

  4. Why Study Chemistry? • To connect Genesis and chemistry • Man is created in the image of God. • Creation Mandate

  5. Creation Mandate Man is to exercise good and wise dominion.

  6. Why Study Chemistry? • To connect Genesis and chemistry • Man is created in the image of God. • Creation Mandate • Dominion science

  7. dominion science scientific activity that seeks to bring glory to God and benefit other humans by controlling aspects of creation

  8. Why Study Chemistry? • To understand the purpose of science • Science does not establish truth. • Science makes models (simplified representations).

  9. Why Study Chemistry? • To understand the purpose of science • The goal of science is workability. • Science always has uncertainty. • It is a matter of faith.

  10. Why Study Chemistry? All worldviews are based on certain presuppositions. • To distinguish truth from error in worldviews

  11. presupposition an idea assumed to be true without proof

  12. Why Study Chemistry? • To distinguish truth from error in worldviews • Naturalistic worldview • Matter is all that exists. • Human reason informed by science is the only reliable path to truth.

  13. Why Study Chemistry? • To distinguish truth from error in worldviews • Naturalistic worldview • Evolution − the Creator= no accountability. • Chemistry exists for humanity’s survival.

  14. Why Study Chemistry? • To distinguish truth from error in worldviews • Christian worldview • The Bible is the ultimate authority. • Seeing the world through the lens of the Bible

  15. Why Study Chemistry? • To distinguish truth from error in worldviews • Christian worldview • God created us as His image bearers. • Man rebelled. • God is implementing His plan to redeem fallen man.

  16. Why Study Chemistry? • To help make life choices • Careers • Life • Logical thinking • Issues • See naturalistic biases

  17. What Is Chemistry?

  18. Chemistryis…. • A Natural Science • A language with its own vocabulary • A way of thinking

  19. Chemistry the study of matter • structure and composition • changes in structure and composition • interactions with energy • properties • takes up space and has mass

  20. Influences on Chemistry • Old Testament Times—The Age of Practical Skill • Focused on practicality • Metallurgy—the process of extracting metal from ore

  21. Influences on Chemistry • Old Testament Times—The Age of Practical Skill • Apothecaries—pharmacists

  22. Influences on Chemistry • Ancient Greece—The Age of Critical Thought • Focused on philosophy and knowledge • Developed critical thinking, but no experimentation

  23. Influences on Chemistry • Ancient Greece—The Age of Critical Thought • Stagnated science for centuries • Four elements—earth, wind, fire, water

  24. Influences on Chemistry • The Alchemists—The Age of Applied Experimentation • Focused on experimentation • Developed sublimation, precipitation, distillation, and crystallization

  25. Influences on Chemistry • The Alchemists—The Age of Applied Experimentation • “transmutation”—tried to change elements (lead into gold) • Paracelsus—started pharmacology

  26. Influences on Chemistry • The Transition—The Rise of Modern Chemistry • Questioned Greek “truths” following the Reformation • Boyle—shattered tradition by proposing a new definition of elements

  27. Influences on Chemistry • The Transition—The Rise of Modern Chemistry • Priestley—discovered oxygen by experimentation

  28. Influences on Chemistry • The Transition—The Rise of Modern Chemistry • Lavoisier— • engaged in careful experimenting and recording • overthrew the phlogiston theory

  29. Chemistry • An academic field since the 1800’s • Different branches developed

  30. Branches of Chemistry • Inorganic—all elements but carbon • Organic—carbon compounds • Biochemistry—chemical processes in living things

  31. Branches of Chemistry • Nuclear—nucleus and radioactivity • Physical—interactions and energy changes • Analytical— • Qualitative: What is it? • Quantitative: How much?

  32. Physical Chemistry Chemistry Physics Biology Biochemistry Biophysics

  33. What Do ChemistsDo?

  34. science the total collection of knowledge gained through the systematic observation of nature

  35. Science • Pure Science— probes world simply to learn new things • Applied Science— searches for specific applications • Scientific Questions— direct and stimulate scientific inquiry

  36. How Do Chemists DO Science?

  37. Scientists … • Notice something which elicits a question • Gather information • Objective information • Unaffected by observer’s personal inclinations and presuppositions

  38. Scientists … • Notice something which elicits a question • Gather information • Objective information • Subjective information • Affected by observer’s personal inclinations and presuppositions

  39. Scientists … • Collect data • Quantitative—numerical • Qualitative—nonnumerical • Use reasoning processes • Deductive reasoning • Applying a premise to many different situations

  40. Scientists … • Collect data • Quantitative—numerical • Qualitative—nonnumerical • Use reasoning processes • Deductive reasoning • Inductive reasoning • Using facts to lead into a conclusion

  41. Scientists … • Make models • To make sense of data • To identify causes and effects • To suggest practical application • To establish connections • To direct predictions

  42. Models are simpler than reality for the sake of workability. Workability is the key to models.

  43. Scientists … • Perform experiments

  44. experiment a repeatable method that involves observing a natural process, sometimes under controlled conditions, for the purpose of analysis

  45. Scientists … • Perform experiments • Record data from experimentation • Empirical data—gathered experimentally

  46. Scientists … • Form hypotheses

  47. hypothesis a simple, reasonable, testable statement that tries to predict the results of an experiment If……, then….

  48. Scientists … • Form hypotheses • Perform experiments

  49. natural experiment an experiment in which the conditions cannot be controlled
