The methods of this lab were all on being conscientious of how organisms are transferred in the lab. The samples were laid out to which specimen was going to be grown where (as shown in the table above). Before the microbes were involved, a poured agar tray was created from a solid agar deep, melted, then poured into a tray. First, an E. coli sample was taken and grown in both section A of the poured agar tray and in the nutrient broth. This included proper aseptic technique and sterilization of both the inoculation loop and the test tube to minimize contamination. Next, a loop of M. luteus was taken from a control test tube and streaked for growth in section B of the agar dish as well as on the slant agar. A proper streaking pattern was used for the slant agar; smearing up the agar slant starting from the intersection of the agar and the glass test tube all the way to the top of the agar. Sterilization and aseptic techniques were used again to decontaminate the inoculation loop as well as to decrease airborne contaminants from the test tubes. Lastly, a sample of S. marcescens was smeared on the final section of the agar dish, section C. The inoculation loop and test tubes were sterilized. Finally, an inoculation wire, or needle, was used to sample S. marcescens for growth as the contaminated needle was penetrated into an agar deep. A mixed test tube of all three microbes was used for a distribution technique. This included a four-pull method to spread out the mixed microbes…

needs these separation techniques in order to have the separate substances. Dependent Variable: The masses of the materials and the mixture. This is measured by using the balance this is the best way of weighing the mass because this is the easiest way to measure mass. Controlled Variable: The original amounts of the mixture. This is the controlled variable because during the lab, the chemist is trying to obtain the original amounts of each of the materials. Materials: - Heating Plates -…

The first and foremost procedure for this lab is to be familiarized with the lab equipment. The principle components to be interacted in this lab is the work station, the wind tunnel, the AOA adjusting handle, the airfoil with tufts, and the wind tunnel frequency controller. Switch the control mode for the tunnel frequency controller to be LOC or local of local control would be used instead of remote control. Make sure that the tubes are connected in a way such that the air and pressure should…

The procedure involved the process of a trial of series in which one could determine if it is possible to begin with copper, create several copper compound reactions, and still recover copper after these reactions have taken place. Before the start of this lab, it is to be assured that all group members are dressed properly in PPE including lab coats, goggles, and gloves, as this lab involved working with chemicals and creating a toxic gas. To begin, a sample of copper metal wire was cut and…

All of the procedures that I will be doing is as if there was nothing wrong and everything were to go on track. First, I would try to get all of my materials all in around the same time span so that I can get started immediately. Getting the indole-3-butyric acid would be the most difficult because once I buy the chemical, I would have to wait for it to deliver because I would be buying it online. Since the chemical is the most important ingredient to my experiment, it puts me in a temporary…

Task 2 & 3: A. Pile the seaweed up on the tin lid supported on a tripod and begin heating with a strong Bunsen flame. It may have to be added a portion at a time during the heating, given the quantity to be reduced to ash. When all has been turned to ash, about a dessertspoonful of residue will remain. During the experiment we piled the seaweed into a tin container and placed it on top of a tri-pod which was placed over a Bunsen burner allowing the seaweed to burn and inevitably turn into ash so…

During the laboratory section two devices were used; these were the DE2-115 board and a computer, containing the software system Quartus II. Each of these devices were very significant for gathering information during the duration of the lab and shall be explained further. The DE2-115 board was the device provided in the lab that displayed the output for viewing by the student. The portions of the DE2-115 board that were used during the duration of the lab were the switches, the LEDs, and the…

Methods For the experiment these will be the supplies you need. • 10 petri dishes • 10 pieces of cooked pasta • Stopwatch • Glove (s) • Incubator (controlled heater and small room) • Camera • Masking tape and marker • Cotton swab (disinfected) • Distilled water (cup) As the experiment was first thought of when food was dropped on the ground and pondered if it was edible. First thought out to test the five second, but developed to test to see if the amount of time food was on the floor affected…
