  1. Nature of Science (NOS)

  2. Science Discoveries? • Joseph Priestley – oxygen (1774) • Carl Linneaus – scientific classification (1735) • Dmitri Mendelev – periodic table (1869) • Antony van Leeuwenhoek – microbes (1674) • Gregor Mendel – heredity (1866) • Albert Einstein – space & time (1921)

  3. Traditional Ecological Knowledge TEK “The ancients knew something that we seem to have forgotten. All means prove but a blunt instrument, if they have not behind them a living spirit.” Einstein

  4. TEK Videos • What was/is “known?” • Is this knowledge “science?” • How do you defend your response?

  5. Eurocentric Traditions vs TEK • Genetics • Gregor Mendel vs. Native Americans cultivated corn through selection processes & oral traditions • Vaccination • Edward Jenner (Gloucesstershire) 1796 vs. Onesimus (1721) an African American slave who told master (Cotton Mather) about smallpox vaccination as a child

  6. Eurocentric Traditions vs TEK • Cesarean section & antiseptics • Missionary doctor in E. Africa saw tribal surgeon use banana wine for woman in childbirth & on knife for removing child. Hot irons for cauterization & cactus spike sutures • Quinine • Dr. Ross (Nobel Prize) vs. Incas who used “bark of barks”for illness, including malaria

  7. More TEK • Natural history of animals/plants • Phenology • Agriculture: corn, beans, potatoes, squash • Grassland management • Use of rubber • Biological pesticides • Boat design

  8. Scientific Method • Francis Bacon (1561-1626) the third and most noble ambition for man was “to establish and extend the power and dominion of the human race over the universe....We cannot command Nature except by obeying her and understanding her.”

  9. Combining Science & TEK • Identify what is known, by whom • Describe how the knowledge was developed. • Help understanding through “border crossings” • Describe its value to society. • Compare knowledge from contexts • Explain how it fits within general cultural understanding.

  10. Science for ALL • Involvement • Role Models • Respect
