BIOL 3702 Lecture Videos

(January 1, 2021)

Welcome to the web page that contains links to a selection of videos associated with BIOL 3702, the lecture course for Microbiology taught by Dr. Cooper in the Department of Biological Sciences at Youngstown State University.  Many of the linked videos presented here are used in lecture.  A separate web page contains links to laboratory-related videos.  

These video links are presented to help students enhance their understanding of the lecture material, and perhaps to entertain students as well.  Certainly, students should use these videos in their study efforts. 

The sources for some of these videos include Crash Course, Amoeba Sisters, Bozeman Science, and McGraw-Hill Animations, and McGraw-Hill Higher Education.  Others were simply collected from reliable and authentic sources.  As other notable and relevant videos are discovered, pertinent links will be added to this web page.  Students may wish to check back periodically.

Notice!  Many of these videos linked on this web page are the copyrighted property.  Other videos linked herein are available to the general public via the internet and vary in copyright.  Regardless, the videos posted herein are solely for educational purposes of students enrolled in BIOL 3702 others who are interested in the microbiological sciences.  Videos that are copyright protected, though posted here, should never be copied, directly distributed, or otherwise used without permission of the copyright holder.

All original material contained in the web page is the intellectual property of Dr. Cooper.  Students and instructors of all educational institutions are welcome to “borrow” any of the original materials (NOT copyrighted materials provided the same restrictions for the distribution of this material required of the laboratory component of this course are followed.
