The very first day of the Unknown project I was acquainted with Denise who was very friendly and was very nice as far as assisting me in the project. The first day we were introduced too various different forms of the unknown such as broth‚ Blood agar plate‚ MSA plate‚ MAC plate‚ and the EMB plate. Before that we had done the 3 phase isolate which we had a possible of 10 points of achieving. In the isolation plate we had too take the sample of our unknown‚ which was the letter G. After we had

loops were sterilized by setting them above the cone of the flame to make the loop red‚ then left them to cool in the test tube tack for streaking. The media included a liquid (YED media that was made by 3g yeast extract‚ 6g anhydrous dextrose‚ 6g agar‚ and 300 mL tap water). The liquid media was on a hot plate‚ then an oven mitt was used to carefully transfer onto 4 petri dishes at a tilted angle‚ with the petri dish lids at an angle as well to reduce airborne contamination. After the end of each

to Volume ratio in Agar Introduction: What is an efficient way to maximize mass but minimize diffusion time in cell? Answer: An efficient way to maximize mass but minimize diffusion time in a cell is to increase its surface area. If you increase the surface area of a cell relatively to its volume‚ then the diffusion time will decrease. Materials: Agar cubes‚ bromothymol blue- pH indicator‚ vinegar‚ ruler‚ spatula‚ beaker. Methods: I used agar cubes as cell models. The agar was cut into blocks

For my science exit project I decided to do a project that revolves around bacteria. I was suggested to do a project where I get a petri dish containing my oral bacteria and see the effects of liquid on my oral bacteria. I was very curious about this topic and wanted to know how the bacteria grows so I gave it a shot. For my project‚ I was told to make an “if and then” hypothesis. My hypothesis was that “If I put orange juice on a petri dish containing my oral bacteria then the bacteria on the petri

What can speed up the decay of bread? Aims In this activity you are going to think about the conditions that would affect the speed at which bread decays and then design a fair test to investigate one of the. This will help you to understand all the points you need to consider when planning an experiment. Safety If you perform this activity: * Do not taste any food. * Wear gloves when handling food. * Wash your hands when you have finished setting up your experiment. * Your
