Characteristics of Living Things Lab
Objectives:
1. Observe living organisms and write down observations for each organism found.
2. Observe any characteristics that make the living things alive.
3. Find the approximate size of the organisms.
4. Draw accurate, detailed diagrams of the organisms observed.
Procedure:
1. Using an eyedropper, transfer a drop of the sample of water onto a clean slide. Add a cover slip
at a 45˚ angle onto the specimen. Observe the slide you prepared under a microscope under low
power and then high power if needed.
2. Draw a diagram of all the living organisms. If you can’t tell if a thing is living, ask the teacher.
3. Include in your diagrams:
a. Possible identification of the organism
b. Total magnification (ocular lens X objective lens)
c. Approximate size of the specimen
i. Fill in the following calibration chart for each objective by viewing a ruler under
each lens and writing the diameter of the field of view.
ii. Estimate specimen size using your calibration chart.
