Engineering Laboratory (Lab) Report Department of Engineering Faculty of Engineering and Science‚ University Tunku Abdul Rahman (UTAR) 1. Introduction Laboratory (Lab) reports are the most frequent document written by engineering student. These reports can contribute a significant amount of marks and yet little time or attention is devoted in understanding on how to write them well. The aim of this document is to provide a general guideline on writing a lab report. A lab report should not be

Problem or Research Question: How does zinc effects the color change in a copper penny? Hypothesis: If copper and zinc comes together‚ then it will form brass‚ which gives gold color to copper penny. Variables: There were no variables at this experiment PROCEDURES: Materials: Zinc (SN) filling‚ 3M NaOH solution‚ Copper penny‚ tongs‚ Hot plate‚ 100 ml beaker‚ 250 ml beaker‚ Bunsen burner‚ Water‚ Spoon. Procedure: First‚ we turned on the hot plate. Then‚ we filled 250 ml beaker with 125

kN/m3‚ and 19 kN/m3‚ respectively. It can be observed that the values are relatively large‚ this is because the soil sample is fully saturated. However‚ the results of each test using different vane sizes yielded different values. The differences in the values can be caused by 1) Personal Errors‚ 2) Overburden Stress 3) The moisture content of the soil and the 4) condition of the soil. Since the whole experiment is done by eye‚ it is very much susceptible to personal errors; a group member could have

6) Observe and record the initial volume of the NaOH buret. Note the markings on the buret. 7) Begin the titration by twisting the lever on the side of the buret until small drops come out. Keep swirling the solution until a pink color is visible throughout from the phenolphthalein. 8) If over titration occurs ask the teacher for further instruction. 9) Write down the final volume in the NaOH buret 10) Subtract the final volume of NaOH from the initial volume. 11) Repeat this process at least

Lab 1: Low Nail Company |Scenario/Summary | After making some wise short-term investments at a race track‚ Chris Low had some additional cash to invest in a business. The most promising opportunity at the time was in building supplies‚ so Low bought a business that specialized in sales of one size of nail. The annual volume of nails was 2‚000 kegs‚ and they were sold

Kiley O’Toole Lab Report 3 Purpose The purpose of this lab was to uncover the number of layers of zinc atoms around a piece of galvanized iron. This was done by pouring the hydrochloric acid onto the galvanized iron‚ thus removing the zinc from the piece of metal. Laboratory Procedure 1. Measured and recorded the mass of a piece of galvanized iron using a centigram balance and a ruler 2. Measured and recorded the length and width of the galvanized iron using the ruler 3. Put the

Wanni Lin Biology 110 March 2‚ 2015 DNA Lab BACKGROUND In this laboratory experiment‚ students were introduced to DNA electrophoresis. DNA electrophoresis is an instrument that many forensic scientists use to get a DNA fingerprint as an evidence for crimes. Not only can it be used for forensic science‚ people can use this for paternity test‚ as well as look for evolutionary relationships among organisms. Agarose is used to make the gel that the DNA fragments are going into. Since DNA particles are

as well as wasting very precious resources. Therefore hormones in the plant signal the formation of proteins that inhibit production of chlorophyll and promotes extensive growth‚ ensuring that the plant will reach sunlight as soon as possible. This process is called etiolation. Once the plants reach the sunlight‚ they start the reverse process‚ called deetiolation‚ in which their growing significantly slows‚ they sprout leaves and start producing chlorophyll. Another factor to consider is the
