-Garlic press - 2 Petri Dishes -Radish Seeds (25 seeds per dish) -1 clove of garlic (crushed‚ only used 1.0 g) -collecting qualitative and photo data‚ once a day for one week! Dependent Variable: If the dish with radish seeds and crushed garlic germinate and grew faster‚ than the dish without the crushed garlic. Independent Variable: Radish seeds are sealed in 2 petri dishes‚ 1st dish without crushed garlic and 2nd dish with crushed garlic. Methods and Materials: -1st Petri Dish: We took a

1. The five petri dishes are stored in a refrigerator. The petri dishes are brought to room temperature before the start of the experiment‚ by taking them out of the refrigerator and allowing them to attain room temperature. The petri dishes are labeled A‚ B‚ C‚ D‚ and E. Before starting the … we make sure to wear sterile gloves to avoid transferring other bacteria on hands onto cotton swab/petri dish. 2. The sterilized cotton swabs are first made damp using sterilized water. The swabs are rubbed

chosen. Methods 1. Gather two paper towels and two petri dishes‚ no safety goggles or gloves will be required for this experiment. 2. Place a petri dish on a paper towel and trace the bottom of it so a circle is drawn. Do this twice on each paper towel so there are four separate circles drawn. 3. Separate the top and bottom of each petri dish so they can each be used separately‚ creating four dishes. 4. Label the petri dishes: Distilled‚ .25 solution‚ .50 solution‚ and .75 solution

Question: What antibiotics work best in preventing E. coli k12 from growing; amoxicillin‚ ampicillin‚ or ciprofloxacin? Hypothesis: If ciprofloxacin‚ an antibiotic‚ is added to petri dishes covered in live bacteria and left to sit for four to six days in an incubator at 37 degrees Celsius‚ then the petri dishes containing ciprofloxacin will have the largest zone of inhibition out of all of the other antibiotics tested because research shows that ciprofloxacin in one of the strongest antibiotic currently

Place petri dish A into the incubator with the temperature set to 47°C 6. Place petri dish B into the refrigerator with the temperature set to 5°C 7. Water the seeds every other day for nine days. 8. Measure the grow of the radish seeds from the roots to the leaves every other day for 9 days. Control group: 1. Label one petri dish C 2. Get a paper towel‚ fold it‚ and wet it with 15 ml of water and put it into petri dish C. 3. Put 6 seeds into petri dish C. Name each

was determined what antiseptic or disinfectant was able to best inhibit this kind of bacterial growth. Nutrient Agar was poured into a Petri dish with four quadrants and then a pipette was used to place bacterial culture on top. Using forceps‚ a filter disc was dipped into each inhibitor and then into a separate quadrant of the Petri dish. The lid of the Petri dish was taped on using masking tape and then

The materials used in the process of the petri dish were the petri dish. Then the nutrient agar was used in the petri dish. Also a cotton swab(Equate) was used in the process as well. The last thing used was 2 pieces of tape to close up the petri dish. First the tape was taken off the petri dish. The Equate Q-Tip which was bought from Sam’s Club. After the petri dish was taken to the bathroom to grab the sample needed for the petri dish. Then the Q-Tip was rubbed about 7 to 8 times in the
