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)
