MATERIALS: petri dish, tape, marker, microscope, incubator, bacteria slide, nutritious agar, distilled water, crystal violet, cockeyed pin, inoculate, butzen burner, slide, beaker, staining tray, tissues, notebook computer PROCEDURE: ingathering bacteria: 1.First get all the materials that are needed. 2. Divide the petri dish into four equa l parts, and number separately section. 3. ! Take a serviceman of tape, about 1 Â½ adjoin long and place it on the outside glass of the fish tank. Then outcome over the petri dish so no water gets on the augar and open the cover of the dish. Quickly and piano place the piece of tape on the ogar, and then subscribe the tape off, close the cover of the dish and throw the tape away. Do this tether more...
