The Living Protists Lab

Click here to view product.

The microscopic world is fascinating to students. Students of all ages love to look at living organisms under the microscope. 

I just spent the last three days in the lab with my biology students observing a variety of living protists.  I use this lab for both my standard Biology I students as well as my AP Biology students.  No matter what the age or the ability level, kids love this lab!  

This lab provides an extensive look at many different species of living algae and protozoa. 

To complete this lab as written, you will need to order the following protist cultures from a biological supply company. 
1) Spirogyra
2) Algae Survey Mixture (Contains 6 representative algae)
3) Diatom Mixture
4) Protozoa Survey Set (Contains 6 representatives: Ameba, Euglena, Paramecium, Spirostomum, Stentor, and Volvox)
5) Marine Dinoflagellates
6) Preying Protozoa Set

This lab was written with a high school biology class in mind, but it is so easily adaptable to younger ages.  This is one of those labs that just gets kids excited about science.  I have not had a student yet who did not enjoy watching these amazing organisms under a microscope.  Even students who have shown no previous interest in your class will perk up during this lab.  

Happy Teaching!


  1. what structure contains the amoeba's DNA ?

  2. Since the Ameba is eukaryotic, the DNA would be found inside its nucleus.
