Apologia 2.2 Pond Life part B

This is a continuation of the work of our cultures.  Since the cultures will need a baseline to compare to, the students used their cultures to create slides (also contributing to their knowledge of how to work a microscope) and viewed them.  They looked for (and found) many organisms.

See below for some of the findings:

For my students, look at the photos and see if you can identify any of the organisms.  If you did not find any in your samples in class or were unable to see some of the other slides, you may use these pictures for your lab.
