The procedure for Lab 5 contained four parts. For Part A, a clean, dry 100 mL beaker was obtained and filled with 60 mL of distilled water. Next, the beaker was placed on a ring stand with a thermometer attached to the ring stand to record the temperature of the water. After the thermometer had been in the water for two minutes, the temperature was recorded. Following the recording of the temperature, a 10 mL pipet and a bulb was used to pipet 10.00 mL of distilled water into a clean, dry,…

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…

Methods There are many important factors to any experiment, including the materials. To continue, the quantity of materials for this experiment varies from a refrigerator to tweezers, but they all need to be included for the best results. First, the larger materials needed to complete the experiment are refrigerator, freezer, stove, one ice box, one scale which could be large or small, one blender, one cooking pot, one large jar or cup, and at least 400 milliliters of distilled water. Next, the…

Methods: Materials needed: Bottled water, control (tasteless) strips, PTC testing paper with ~ 0.003mg per strip, 1-inch strips of black licorice. 1. Provide each student with one large medicine cup filled of water. 2. Each student rinse his or her mouth of any residue prior to tasting the PTC paper with water to avoid misreading for data collection. 3. Give each student blindly a tasteless paper strip as a control. 4. Have each student again rinse his or her mouth of any residue then proceed…

1. Clinical Laboratory Scientists/ Technician a. Career Title: Clinical Laboratory Scientists/ Technician b. Salary: $40,000-$60,00 c. Years of school: 2-4 years d. Very briefly summarize the overview: Clinical Laboratory Scientist/ Technician (also called medical scientists or medical laboratory technicians) are highly skilled scientists who discover the presence or absence of disease and provide data that helps physicians determine the nest treatment for the patient. In addition, CLS collect…

A strip of magnesium (Mg) ribbon was cut with a scissor. Said piece had a length of 6 cm, and a weight of 0.071 g. The magnesium piece was rolled into a compact ribbon. After that, with copper turnings the mg piece was covered. Next, 700-mL of water was placed into a 1000-mL beaker. Then, the copper-wrapped magnesium was placed in the beaker. A 100-mL graduated cylinder was filled completely with water. After, said cylinder was covered with a small piece of paper towel over the entire rim, and…

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…

1. Items needed for this experiment are: three nutrient broth tubes, graduated pipet, alcohol, disposable cups, E. coli, S. epidermidis vials, yeast packet, candle, lighter, permanent marker, paper towels, bleach, safety gloves, goggles, face mask and apron. 2. Before beginning the experiment, wash hands with soap and warm water, then put on apron, safety goggles, face mask and gloves. 3. Disinfect the work area with bleach and paper towels. Then pour some bleach in a bucket for anything that…

I strive to enhance the quality of human life. The human race is plagued with disease, disorders and societal plights that treatment with traditional medicine would cease to assuage the recurrent issues. For example, diabetes is currently one of the top health challenges in the United States. The influx of diabetic patients will not decrease with insulin treatment alone, one must alter their injurious diet. Physicians are expected to treat patients based on symptoms. The analysis is then capped…

Original Hypothesis: Prior to performing any measurements or calculations in the lab, it was originally hypothesized that the 10 mL volumetric pipette would be the most precise and most accurate instrument, while the 10mL graduated cylinder would be the least precise and least accurate instrument. Sample Calculation: For the 10 mL volumetric pipette, three weight of water measurements were taken by first weighing a beaker on the scale, measuring 10 mL of water with a volumetric pipette,…
