These are pictures of Paramecium they are swimming around in water this is evidence that they are living! Me and my class had a vial full of them and we used an microscope and studied them watching them move also watching them eat! What my teacher Mr. Gonzalez did was die the yeast that they eat red and put it with the Paramecium. To see if they ate the yeast we looked to see if they had red on them. There was a problem that some of the water absorbed the red die so it was kind of red but if we looked good enough we saw that they did eat some! Watch this video and see for yourself(I'm sorry the video taker i used speeds it up so pause or slow the video down if you want).
