Title: Scientific Method


1
Scientific Method
  • Basic Steps
  • (The Rattlesnake Experiment)

2
Definition
  • Scientific method basic steps that scientists
    follow in uncovering facts and solving scientific
    problems

3
Basic Parts of Scientific Method
  • Stating the problem
  • Gathering information
  • Suggesting an answer for the problem called a
  • HYPOTHESIS!!!
  • Performing an experiment to see whether the
    suggested answer makes sense
  • Recording and analyzing the results of
    experiments or other observations
  • Stating conclusions

4
Stating the Problem
  • What invisible trail does a rattlesnake follow in
    tracking down its bitten prey?

5
Gathering Information
  • A rattlesnakes eyes are only sensitive to visible
    light
  • A pair of organs located under the eyes detect
    invisible light in the form of heat
  • A rattlers tongue smells certain odors in the
    air
  • The sight or smell of an unbitten animal does not
    trigger the rattlers tracking action

6
Hypothesis
  • After the snake wounds its victim, the snake
    follows the smell of its own venom to locate the
    animal

7
Experiment
  • Drag a dead mouse that has been struck and
    poisoned by a rattlesnake along a curved path on
    the bottom of an empty cage
  • Place the snake in the cage
  • The snake follows the exact trail that has been
    laid out
  • Control
  • Drag an unbitten dead mouse along the path
  • The snake seems disinterested

8
Recording and Analyzing Data
  • Do the experiment many times
  • Record the data

9
Conclusion
  • The scent of venom was the only factor that could
    cause a rattlesnake to follow its bitten victim.
