Do this to each of your dishes. 33. Now‚ take one petri dish‚ placing it on your paper and let the numbers face right side up. Along the bottom of the lid‚ write ‘Gain-A’. This label will be used to remember what the dish is containing. And place that dish to the side‚ holding the petri dish properly.

lantern was poured into two Petri dishes in each of the four stations. One was used for the control and the other dish was used for the experiment. To each of the Petri dishes 1 mL of buffer solution was added. At station 1 the control two drops of ATP were added to each Petri dish. The control Petri dish was left alone and a pipette was used to deliver several drops of acetic acid to the experimental dish. Several drops of sodium hydroxide were added to the experimental dish. Results were observed

soap was added. After adding the food colouring into the water‚ the food colouring slowly began moving towards the center of the Petri dish. After adding the food colouring into the milk‚ the food colouring instantly sinks towards the bottom of the Petri dish‚ and slowly disperses. After about one minute of the food colouring sitting on the bottom of the Petri dish‚ it then begins to move upwards once again and separates. After adding the food colouring into the oil‚ it stays in the same spot‚

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

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
