  1. Scientific method By Daniel Witt

  2. Observation • What is noticed • This plane is big.

  3. Research question • What you are trying to learn • If ___ than___ question • Are Jet engines more powerful than regular engines?

  4. Hypothosis/theory • Hypothesis- what you think will happen, this car goes fast. • Theory- tested thousands of times and believed to be true, this car goes really fast.

  5. Pure and Applied Sciences • Pure science- Trying to figure out big questions, like what the meaning of life is, evolution, etc. Often has little to no effect on present life. • Applied science- Science that effects us right now, how can we get more lift out of aircraft, how can we retard global warming.

  6. IV, DV, CV • IV- independent variable (what you change) • DV- dependent variable (resulting change) • CV constant variable (never changes) • Eg. High wing vs low wing planes; IV is wing hieght, DV is handling

  7. Fair test Non-opinionated test

  8. Bar/line graphs • Bar used when time is not a factor • Line used when time is a factor.

  9. Inferences • What is believed to have happened

  10. Mean/Median/Mode • Mean- Determined by adding all numbers than by dividing how many total numbers there are • Median- determined by arranging all numbers numerically than removing one from each side • Mode- number that appears most often

  11. Control/ Experimental groups • Control- No change; the regular moped • Experimental- change; the “manly” moped with twin jet engines.
