Lab Report: Scientific Method Your Name: Alyssa Melincoff Purpose of this Lab What is the goal of this lab? What question is it trying to answer, or what problem is it trying to explain? To find out how table salt affects the boiling temperature of water. Hypothesis After reading the lab instructions - but before starting the lab - record your best â€Å"educated guess† about what will happen in the experiment. What hypothesis can you generate about the effect of adding salt to water? Adding table salt to boiling water will cause the water to boil at a higher temperature Experimental Design List the materials used in this lab, and the procedure you followed. Materials: 1.Kitchen Stove 2. 2 cup measuring cup 3. sharpie†¦show more content†¦Use the digital thermometer. Record the temperature when the pot reaches a rolling boil. Data Record the data you collected in the lab. (The data table and the graph.) Table 2. Boiling point temperatures of various salt solutions. Beaker/Concentration of NaCl (M) Boiling Point Temperature ( °C) Analysis Analyze the data you collected in the lab. How does the data presented above relate to the hypotheses you generated earlier in lab? Are any hypotheses disproved by your experiment? Use your graph to determine the boiling point of a solution made with 2  ½ tablespoons. This use of a graph has generated a hypothesis that a 2  ½ tablespoon solution boils at __219__degrees F. Prepare a 2.5 M solution and verify your hypothesis.Correct! †¢Is the hypothesis correct? Yes. Adding table salt to water causes the water to boil at a higher temperature. †¢Problems with doing the experiments. The temperature readings were hard to make. Gloves had to be worn to keep my hands from getting too hot. Had to be careful that the stove heat was not hitting the thermometer. †¢Other things learned. Be careful when adding salt to boiling water. It makes the water boil vigorously for a second or two. Conclusion After conducting the experiment, how would you now explain the problem(s) or answer the question(s) raised when you described the purpose of the lab? Be sure to base your answer on the data you collected.

It was hypothesized that the relative amount of starch consumption was very high for my personal ancestral diet, thus my AMY1 diploid gene copy number in my genome and salivary amylase concentration would be significantly higher than the population mean.

The DNA fragments, after cutting has occurred, are separated using agarose gel electrophoresis. The DNA fragments are placed in the gel, and an electric current is run through the matrix of the gel-like agarose. Migration of the fragmentsRead MoreBiology Beetroot Lab Report2895 Words   |  12 Pagesusing this knowledge gained. A risk assessment has been conducted in the process of planning this investigation and the possible risks may be glass breakage or burnt by hot water. These dangers can be prevented with more careful actions around the lab. It is also essential that safety glasses are worn during the entire course of the experiment. Method: 1. Take all safety precautions: wear safety glasses, hair tied back, wear close-toed shoes, ensure a clear surrounding with no obstacles inRead MoreMolecular Genetic Experiment : Biology Lab1793 Words   |  8 PagesExploring the Expression of an Auxin Induced Gene pCNT103, a Constitutive Gene GapC and a Cytokinin Induced Cig1 Gene in the DNA and RNA Extracts of Differentiated Shoot, Root, and Callus Tissue of Nicotiana tabacum Demaris Gonzalez Genetics Lab Professor Kamil Starczak March 23rd , 2017 Abstract: The experiments purpose was to understand and observe the gene expressions in the genes pCNT103, cig1 and GapC in the shoot, root and callus tissues of the tobacco plant, Nicotiana tabacum.
