Measurement

Moment of Inertia for Rotating Objects Lab Report For this lab, the guiding question that needed to be answered was: For the system shown below, is there a functional relationship between the rotational inertia of the rotating object and the time required for the hanging mass to fall a known distance that can be determined experimentally? (as seen in Figure 1) Before beginning to attempt to answer the question, the lab had to be set up correctly. First, the rotating object was set tangent to…

Most important type of validity is the Construct Validity. Any research is impossible without employing constructs (Shadish et.al, 2002). In every research, we aim to understand or imagine constructs and measure their indicators to make inferences as well as judgements. Locke (2012) explains that construct validity is nothing but validating such constructs depending on their correlations with other variables that are indicators or theoretically related to the constructs in question. In order to…

Health Measurement: Purposes and Key Determinants Population Health means health outcomes and their distribution within the group of people. In other words, it is a health approach with a purpose of improving health of human population in whole. This improvement is achieved due to number of wellness activities aimed to support the purpose. However, in order to manage this improvement, population health should be measured and determined. Three main purposes of population health measurement are…

length and width of a wrench jaws, and the length and width of the cutting edge of the chisels. As mentioned previously, class characters were also recorded for the tool marks themselves. These class characteristics include, but are not limited to, measurements of the length, width and depth (if applicable) of the…

In this experiment my partner and I will set up a chemical system arrangement in order to determine the effectiveness of neutralizing of a commercial antacid, per gram. When the arrangement is set we will test the different variations of the experiment, for example during step A we will be my partner and I will be determining the mass of the antacid and preparing the antacid for analysis. For step C my partner and I will be using what we have recorded in order to complete the calculations.…

The Evolution of TPACK Technological Pedagogical Content Knowledge (TPACK) is a framework for teachers in how they make connections between pedagogy, content knowledge, and technology (Koehler & Mishra, 2005). This paper briefly discusses the evolution of this theory, its strengths, and challenges it presents. Article One: Reviewing the Literature Voogt, J., Fisser, P., Pareja Roblin, N., Tondeur, J., & van Braak, J. (2012). Technological pedagogical content knowledge - a review of the…

As technology continues to advance, romantic relationships are continuously challenged to evolve and adapt with media. Many issues arise with social networking sites like Facebook, Twitter, and Instagram. These sites may generate jealousy, uncertainty and questioning of satisfaction within a relationship. The authors’ purpose was to research the relationship between FB relationship maintenance behavior and satisfaction, uncertainty, and jealousy in relationships. The authors’ first hypothesis…

What factor(s) affect the rate of reaction? Problem: What effects does temperature have on the rate of reaction? Purpose: The aim of this investigation is to investigate how changing the temperature of sodium thiosulphate affects the rate of reaction in a chemical reaction. In order to complete this practical the temperature will be changed three times and the rate of reaction will be measured each time. Variables: Independent: -the temperature of the sodium thiosulphate. Dependent:…

The essay is divided into four sections, separated by whitespace. What do each of the sections accomplish? The four sections are each divided based on how to dumpster dive. The author wants the reader to know how he dumpster dives and informs the reader on how to do so. In the first section he claims that when you first begin scavenging, you are filled with disgust and self loathing. In the second section he lets the reader know many people think of it as an art and the objects they find. In…

Rabia Iqbal Biol 395-1005 lab 01/31/2015 Broadford assay Absorbance Figure 1. The concentration and absorbance of Bradford assay. Four samples containing Bovine serum albumin, diluent, and Bradford. At 0.25 mg/ml concentration the absorbance was 0.109 nm and the relation between absorbance and the concentration held constant throughout except at the 0.50 mg/ml when the concentration absorbance was 0.186 nm. Figure showed that as the concentration is increased the absorbance elevates also. All…
