  4. Classifying organisms
    according to properties
  5. Taxonomy
    • branch of biology that names and
    • classifies species into groups of increasing breadth

    • Domain
    • Kingdom
    • Phylum 
    • Class
    • Order 
    • Family
    • Genus 
    • Species
  7. 3 Domains
    • Archaea
    • Bacteria
    • Eukarya
  8. Pseudoscience
    • individuals make scientific-sounding claims
    • that are not supported by trustworthy, methodical scientific studies
  9. Anecdotal observations
    • based on only one or a few observations, people conclude that there is or is
    • not a link between two things.
  10. scientific method
    Step 1: Make observations.Step 2: Formulate a hypothesis.Step 3: Devise a testable prediction.Step 4: Conduct a critical experiment.Step 5: Draw conclusions and make revisions.
  11. hypothesis
    • –Proposed explanation for a natural
    • phenomenon

    • –Proposition based on previous
    • observations or experimental studies
  12. theory
    widely accepted hypothesis
  13. living vs non living
    • reproduce via DNA
    • grow and develop
    • take energy from environment
    • sense and respond to environment (plant towards sun) 
    • maintain constant internal conditions (homeostasis)
    • evolve over time
  14. hierarchy of life
    atom, molecule, cell, tissue, organ, organism, population, community, ecosystem, biosphere
  15. Archea
    prokaryotes in extreme environments
  16. Bacteria
