We did a little experiment for Biology that Brandon is taking this year. We had to go to a body of water, pond etc... and gather some water samples. Each sample had to be put in thier own jar.
Each jar had something different like egg yolk, hay, soil and rice. These were different foods for our "hosts".. ick.. lol
After setting for about 4 days you are to look at them under the microscope. There were various ameobe type items floating around in them. Very cool to look at.
