The microscopic world is fascinating to students. Students of all ages love to look at living organisms under the microscope. This lab provides an extensive look at many different species of living algae and protozoa. This lab was written with a high school biology class in mind, but it is easily adaptable to younger ages. Your download will include two versions of the lab: a PDF version and a word document.
This lab is the perfect activity to use when teaching about algae and protozoa. I use this lab as a follow up to my lecture called: The Kingdom Protista: PowerPoint and Notes for Teacher and Student
This document is 19 pages in length. The lab handout for students is 11 pages in length. Space is provided for many drawings, and space is allotted to answer questions. I hope that you will download my free preview in order to get an idea of the formatting that is used. After the 11 page student handout, there is an additional 8 pages of answers and teacher support materials.
To complete this lab as written, you will need to order the following protist cultures from a biological supply company.
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
In addition to these living cultures, you will need the following lab supplies: Compound Microscope, Slides, Cover slips, Protoslo, Cotton balls, Congo Red, Toothpicks.
Three days (assuming a one hour class period) will be required to complete the lab. You can easily shorten the lab by omitting some of the specimens that will be observed. Even though this is quite time consuming, it is one of my favorite labs because my students always enjoy it so much.
