Basic Laboratory Skills
If you missed lab this week, please check the make-up module. It is due next week in lab.
Lab Unit 1 Write up– print and bring to lab if you DO NOT have a new lab manual the first week.
Examining Live Specimens
- Observations: Statements determined by using any one of a person’s five senses (empirical reasoning). It is typically the first step in the Scientific Method and can lead to hypotheses.
- We will be using Microscopes to make Observations of small living specimen and writing descriptions to practice Scientific Communication skills.
Reminders:
- Label all notes with date, time, and place.
- Record all results; don’t rely on memory.
- Make sure to record what you SEE not what you THINK should be there.
- Detail is key, pay attention to even the smallest things.

- Video on How to Use a Compound Microscope
- Directions for determing Total Magnification, Field of View Measurements and Cell Size can be found in your lab manual Unit 1 Activities One to Four.
- Basic Concepts of Microscopy
