Biology Ch 1


How are Science and Technology different from each other?


Science: used to "Understand Nature"

Technology: used to "Apply Knowledge"


How do Science and Technology "depend" on each other?


Science is used to make DISCOVERIESTechnology is used to make INVENTIONS
*More discoveries equal greater inventions, we discover stuff through inventions


What drives science?


Curiosity


What drives Technology?


Wants and Needs


Inductive Reasoning


Form of Discovery Science"Specific to General" (Specific observations to general conclusions)Ex. an individual with black and white strips is a zebra---All zebras have black and white stripes


Deductive Reasoning


Form of Hypothesis Science"General to Specific"Hypothesis --> Experiment


Limitations of Science


"Anything that cannot be tested, proved, disproved"A.GodB. Proving supernaturalC. Faith or Belief


Biology (meaning)


"The study of life"


Cell (meaning and description)


"Fundamental unit of life"1. Enclosed in membraine with passage2. DNA- genetic information3. Two types: -Prokaryotic- simple (very diverse, bacteria) -Eukaryotic- complex (plants, people, mushrooms)


Hypothesis Science Format/Steps


1. Observation (usually from discovery science) leads to wanting an explanation2. Hypothesis (Proposed explanation) must be testable and falsifiable.3. Experiment/Test:Control group- no change; used to compareExperimental group- change of simple variableConclusion- test falsifies or does not falsify hypothesis


Hypothesis must meet 2 conditions:


Testable and Falsifiable


Theory (explanation)


Broad in scope-explains several observations-supported by large amounts of evidence-generates new hypothesis


2 general groups of Microscopes


1. Light2. Electron


Discovery Science


"Describes" natureUses Inductive Reasoningbased on Observations and measurements


Hypothesis Science


"Explains" NatureUses Deductive Reasoning


Homeostasis (explanation)


Regulation of internal environment (PH and temp)Ex. "Sweating in human beings)
