What is Biology

• Chapter 1

2
BIO LIFE

• Interactions of life
• All functioning parts work together to create a
  balance of nature
• All living things depend upon other living things
  
• All living things also depend on their
  environment

3
What is Life

• What is Life 5 characteristics
• Organization orderly structure
• Cells ? Tissue ? Organ ? Organ System ? Organism
• Reproduction production of offspring (creating
  more of oneself)
• Growth and Devlopement
• Growth increase in size
• Development changes throughout ones life
  (maturation)
• Adjustment Homeostasis
• Stimulus any condition that requires and
  organism to adjust
• Response reaction to stimulus
• Adaptation Evolution
• Change over time to become better suited for
  their environment

4
Logy Study of

• Science a process that produces a body of
  knowledge
• Applied science using knowledge to solve
  problems
• Scientific Method process used to study science

5
Scientific Method

• Observation
• Watching the natural world and asking questions
• Question the problem
• Hypothesis
• Solution to the problem
• Educated guess
• MUST be TESTABLE

6
Scientific Method contd

• Experiment
• Techniques used to prove of disprove hypothesis
• Controlled Experiment all variables being
  tested stay the same except one
• Control group the group in which all variables
  stay the same
• Control the variable that stays the same
• Experimental group the group in which the one
  variable is manipulated
• Independent variable the variable being
  manipulated (what your testing for)
• Dependent variable the change that results from
  the independent variable

7
Scientific Method contd

• Data/Results
• Information that is collected from the experiment
• Record information (table and or graphs)
• Draw Conclusion
• Analyze data to prove disprove hypothesis
• If proven redo experiment exact same way
• If disproven redo hypothesis and perform
  another experiment

8
Theory vs Law

• Theory
• Explanation of nature, proven hypothesis that
  withstood test of time
• Big Bang Theory
• Law
• Statements that are factual based, these events
  always occur in nature
• Law of Gravity

9
Research

• Descriptive words
• Used mostly with comparisons through observations
  and conclusions
• Quantitative numbers
• Metric system SI (International Unit of
  Measurement)
• King Henry Died by drinking chocolate milk
