The 3 things present on a good graph

Scientific Method
A way to gain, organize, and apply new knowledge
Steps of the Scientific Method
1. Recognize a problem 2. Make a hypothesis 3. Predict the consequences 4. Perform experiments 5. Formulate the simplest general rule
3 other ways that scientific discoveries are made
1. Trial and Error 2. Experimentation w/o guessing 3. Accidental Discovery
Scientific Fact
A close agreement between competent observers about a series of observations
Hypothesis
An educated guess that is presumed true until experimental test
Laws or Principles
Hypotheses that are tested over and over again but not contradicted
Scientific Theory
A synthesis of a large body of information that encompasses well tested and verified hypotheses about certain aspects of the natural world
What makes a good hypothesis
1. Must have a test for "wrongness" 2. Must be scientific
Explain the difference between science and technology
Science is what we discover while technology is how we use that discovery. Science is neither good nor evil but technology can be used for good or evil.
