Protozoans Video II: In the Eye of the Needle

This 25-minute presentation takes a more in depth look at protozoans. A metric measuring unit, the micrometer, is introduced and with on-screen graphics, twenty different protozoans are identified with their corresponding sizes. The speed of a Paramecium is determined and a number of cell parts and organelles of various protozoa are identified. Learn about the spring-like myoneme on the Vorticella, the cirri of Euplotes, chloroplasts in the Euglena, water expelling vesicles in a Paramecium and see a variety of different shaped nuclei. From a single tiny cell in a Volvox colony to the giant amoeba, Pelomyxa, it's all here and can be seen inside the eye of a needle!

With over 150 illustrations, you'll find the Protozoan teacher handbook to be a valuable resource in itself! It includes worksheets for students, information pages that reinforce topics discussed on the videos, illustrated guides to help you identify unknown specimens and even a student quiz covering each video. Our customers rave about this handbook. Use it and the three videos to teach an exciting, comprehensive unit in protozoology!
