I am Mr. McGee, a high school science teacher but a lifelong scientist with a need for adventure and inquiry. I live near Washington D.C. in the Commonwealth of Virginia.
This is my RU-vid channel dedicated to instruction for my classes, as well as the general public.
The "particals" all move in the same direction, from the bottom of the screen towards the top. As i understand it that is not what we are expected to see; they all should move randomly in different directions. I think you should have used pure water first; show it through the microscope that there is nothing visible, then add tiny particals and show the result. This is a very bad executted experiment and proves nothing. Yes you said that you disolved milk into water, but you can say anything you like, i want proof! Mr Brown didnt use milk, he added polm to water
Thinking that a molecule of oxygen or nitrogen could jiggle around a much more massive fat molecule, is like saying that 100 children with pea shooters can buffet around a boulder with their pea bullets. In reality they will just bounce off and the massive object will not move.
Sir I want to thank you for teaching how to do graphs. I am not at all in your class but I found your video in my time of need for my Bio lab report. Thank you man.
