Lab 1 Objectives
  • Introduction to the Scientific Method and
    Hypothesis Testing
  • (2) Compound Light Microscope Overview
  • (3) Introduction to Physical Measurements

7
Scientific Method
  • A process by which we investigate and understand
    the universe.

8
Scientific Method
  • Ask questions based on observations.
  • How? Qs are better than Why? Qs.
  • How? Qs lead to hypotheses that are
    experimentally testable.

9
Microscopes
10
Microscopes
  • Your desired specimen should first be in the
    field of view and in focus with the 10X objective
  • Then switch to the highest power objective (40X)
    by rotating the revolving nosepiece.

11
Lab Exercise
  • Work with a partner
  • Follow lab manual directions

12
Physical Measurements
  • Estimating Distances
  • Pacing

Physical Measurements
  • Estimating Height
  • Pen Trick

17
Pen Trick Height Estimates
If perpendicular -gt stand back until you see
entire height of the object in height of the pen.
Flip pen 90 and note the points where pen
covers horizontal distance
Pace distance.
