• Scientific Method

• Inductive reasoning: use detailed observations to draw general conclusions.

• Deductive hypothesis: flows from the general to the specific: If ... then ... logic - predictions.
  • Can make predications.
  • Tested by a falsifiable expermient.

• Write a deductive hypothesis for each of these observations:
  1. Fruit fly development from egg to adult speeds up in warmer temperatures.
  2. Increasing amounts of pesticide kill beneficial organisms like songbirds.

• Hypothesis can be a null hypothesis: no difference between experimental and control groups. Example:
  There is no difference in the survival rate of birds subjected to 0.1% pesticide and 5% pesticide ingested in their food.
