The objective of this procedure is to determine the identity of three unknown samples by using two different tests: The Iodoform test and the Tollen’s test. Procedure Part A- Iodoform Test • In three clean and empty test tubes, three drops of each respective unknown liquid were inserted via pipette to their respective labeled test tube (which were labeled according to whatever compound they would contain, i.e. A, B or C). These test tubes were subsequently treated with 2 mL of water and 2 mL…

To begin the experimental set up, grab a napkin/paper and place it under the spot plates. Across the top of the spot plates, on the napkin, write Temperature and label each column using 0°, 25°, 55°, and 85°. Along side the spot plates write Time and label each row using 0, 2, 4, 6, 8, and 10 minutes. Next, acquire four different test tubes and label each of them with a different temperature, label the enzyme source (B for bacterial or F for fungal), add the group number. Obtain another 4 test…

Introduction: This Laboratory experiment mainly focused on the fundamental concepts of basic Chromatography. We had a goal of learning about the properties of color additives, studying their molecular structures, and their rates of solubility when added to a strip of paper and temporarily placed into a beaker of solution. When actually performing the experiment, it is relatively easy and straightforward to do as long as you do not increase the concentration of the dye or leave the wrong side of…

Imagine being locked in a cage with thousands of drugs pumping through your system, not only leaving long-term damage but having the effect to kill you. This is happening to thousands of animals. Animal testing has said to have been around since the third and fourth centuries when pigs and goats were dissected to study their insides. What once started as pure curiosity has turned into people using animals, for almost everything. You have to agree that this is wrong and has to be stopped.…

set of quantitative date, through studying the results derived from their controlled experiment, which they presented as evidence to support their claim. In contrast to this Levine used the discourse analysis approach, and gathered qualitative evidence to support his claim. This leads onto another difference in the methods of research applied during these two varying studies, in that Latané and Darley’s experiments were closely controlled, they were able to introduce variables, and manipulate…

Happiness Leads to Less Stress It’s safe to assume that more stress leads to less happiness, but is it safe to assume that happiness leads to less stress? Questions like these are those that social psychologists ask everyday. Social psychology originates from the broader study of psychology that focuses on human behavior in social settings (McLeod, 2007). There are a variety of research methods that social psychologist can employ such as, correlational, observational, and experimental. The…

even further understanding in research. While this is true Doke and Dhawale state in Alternatives to Animal Testing: A Review “Every year, millions of experimental animals are used all over the world” (224). The use of animals for research and lab experiments is not only an outdated method that harms animals, but is also unreliable and unneeded. Using animals for research and experimentation, while a lucrative business for many, has proven to be not “only unsafe, but also expensive,…

categories. Participants in the misattribution category were told the supplement had some side effects such as tenseness, anxiety, and increased heart rate. The second, control category was told the supplement had no side effects of any kind. In this experiment the independent variable being the categories, and the dependent variable being the results from the participants. The participants were then given a green colored drink to ingest. Immediately after, they were given the Spielberger 20…

my lack of memory of science from grades k-12 is a reflection of poor and uninspiring teachers that did not show me that science could be fun and touches on multiple elements of the world. Science was always portrayed as just one thing such as, experiments and playing with chemicals. It was never expressed as something that was all around…

Hypothesis This study attempts to assess two research hypotheses. Our hypothesis answers the research question, what difference, if any, can be found between the two concentration when describing dissertation characteristics? Our first hypothesis (H1) states that clinical track dissertations are more likely to be experimental than administrative track dissertations. Our second hypothesis (H2) states administrative track dissertations are more likely to have advanced statistical analyses than…
