  1. New Core Curriculum week 2, class-1 Foundations of Scientific Process Theories and Scientific Laws Science vs. Pseudoscience

  2. Movie “Contact” http://www.youtube.com/watch?v=SRoj3jK37Vc What ? Where ? How ? Why ? Scienceis concerned with investigating and making sense out of the environment and trying to predict future observations.

  3. Theory&Scientific Law Theoryis defined as a broad, working hypothesis that is based on extensive experimental evidence ex. Plate Tectonics Theory http://en.wikipedia.org/wiki/Plate_tectonics When theory is around for a long time it is sometimes promoted to a “Law of Nature” of Scientific Law Scientific Law describes what is happening in nature (how it is, not how it aught to be)

  4. Science vs. Non-science vs. Pseudoscience

  5. Pseudoscience: deceptive practice that uses the appearance or language of science to convince, confuse or mislead people into thinking that something has scientific validity when it does not Examples ?

  6. Scientists are healthy skeptics Questions to Ask ?

  7. Phrenology Franz Gall (1758-1828) Study of personality characteristics by measuring bumps on the head Famous Anatomist Gall: So observed these facile memorizers and “I noticed that they all had large and protruding eyes .”

  8. The Theory of Phrenology: Assumptions 1. Physiology 2. Behavior Basic innate traits Brain has different, distinct areas. 3. Connection Different areas responsible for different traits. b. The larger the brain area, the more prominent the trait.

  9. You need measurements to test a theory Bumps on skull (couldn’t measure brain)

  10. The Theory of Phrenology

  11. The Theory of Phrenology: Pseudo-science popular in 19th century. Karl Marx Advertisement for a Phrenology Lecture- 1888 Charles Darwin Gregor Mendel

  12. ? President Andrew Jackson (1767-1845) President 1829-1837 Reference appears in the Congressional Record in 1834. Senator Henry Clay (1777-1852) Clay suggested that the President’s head should be examined by phrenologists and that they would “find the organ of destructiveness prominently developed.”

  13. The Theory of Phrenology: Why it failed ? Wrong & too simplistic measures of brains activity

  14. Scientists are healthy skeptics

  15. Arsenic-based bacteria: Fact or fiction? Steven Benner, a chemist at the Foundation for Applied Molecular Evolution in Gainesville, Florida told New Scientist: “In order to measure the apparently modified DNA, it has to be put into a water-containing gel, which would rapidly dissolve any arsenic-containing chunks of DNA, but not those containing phosphorus. Since they found large chunks of DNA, it must contain phosphorus, not arsenic...”
