Biology Chapter 1 (Introduuction)
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 DISCOVERIES
Technology is used to make INVENTIONS
*More discoveries equal greater inventions, we discover stuff through inventions
What drives science?
What drives Technology?
Wants and Needs
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
Form of Hypothesis Science
"General to Specific"
Hypothesis --> Experiment
Limitations of Science
"Anything that cannot be tested, proved, disproved"
B. Proving supernatural
C. Faith or Belief
"The study of life"
Cell (meaning and description)
"Fundamental unit of life"
1. Enclosed in membraine with passage
2. DNA- genetic information
3. 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 explanation
2. Hypothesis (Proposed explanation) must be testable and falsifiable.
Control group- no change; used to compare
Experimental group- change of simple variable
Conclusion- test falsifies or does not falsify hypothesis
Hypothesis must meet 2 conditions:
Testable and Falsifiable
Broad in scope
-explains several observations
-supported by large amounts of evidence
-generates new hypothesis
2 general groups of Microscopes
Uses Inductive Reasoning
based on Observations and measurements
Uses Deductive Reasoning
Regulation of internal environment (PH and temp)
Ex. "Sweating in human beings)
