HYPOTHESIS: I believe if the bacteria are taken from a say more used then more will gain on the spot of the knockout where the tape was endued.

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 PROCEDURE: ingathering bacteria: 1.First get all the materials that are needed. 2. Divide the petri dish into four equal parts, and number each section. 3. Take a serviceman of tape, about 1 ½ inch 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 gently place the piece of tape on the ogar, and then take the tape off, close the cover of the dish and throw the tape away. Do this tether more...
