Observations and Measurements

random errors on the data. The graph can be used to detect random errors through the amount of scattering in the results. Improvements could occur, with numerous trials, therefore, conducting an average of trials to minimise the effect of inaccurate measurements on the…

Diagram of Prototype A that consisted of an octagonal prism with a length of 11 in. or 27.94 cm. and height of 10.16 cm., while we created corrugated layers within the prism. We decided to change all the dimensions to centimeters instead of using inches as the units. Tinkercad model of Prototype B that consisted of a hexagonal prism with a length of 27.94 cm., height of 10.16 cm., and sides of the base of 4.445 cm. WIthin the hexagonal prism consisted of 6 equilateral triangles are connected…

Sit and reach test was a test to see how flexible your hamstrings are. You had to sit with you feet flat against a board and try and push the measuring scale to see how far you can reach. This test was a really rough test for me. I have always had really bad hamstrings and sense I can remember I have never been able to touch my toes. However, I was not expecting such a lousy score. I got a whooping 17 cm, which is beyond pathetic considering the needs improvement scale is below 24 cm and good is…

The Purpose of this Lab: The purpose of this lab was the help the experimenter gain a better understanding of consolations by helping the experimenter be able to identify the circumpolar constellations, understand the effects of earth’s rotation on viewing consolations, be able to use the Sky Map app, and to describe the characteristics of an astronomy photograph. Description of the Materials: Within this lab, the experimenter uses the Sky Map or SkyView in order help label and identify various…

In this extension experiment there were a few errors that occurred in some of the trials. This is to be expected as perfect sterile techniques are unable to be achieved in the conditions provided. This is also why it was chosen to do three trials of each antiseptic so when errors do occur they can be easily recognised as anomalies. In the Domestos trials the main error was in the second plate where no results could be found for any of the four sections. As can be seen in the photo a small…

how the children that took a nap were better able to recall the learning verbs. b. How is it measured? (self-report survey, self-report interview, ethnography, naturalistic observation, systematic observation) ¬ This study was measured by systematic observation. Systematic observation is when there is a careful observation of one or more specific behavior in a setting. (Dyer, 2017) For example, within the context of the article we can infer that Sandoval and her colleagues were looking at the…

that would cause the object to exhibit behavior that is not probable. Being able to predict what an object is going to do with accuracy does not even come close to eliminating uncertainties that affect science in big ways though. In nearly every measurement in every experiment, there is some level of uncertainty. Some measuring tools are more accurate than others but the farthest number to the right of a decimal point is usually rounded which can seem to have little effect on the end calculation…

The article, “Effects of new smoking regulations in Italy” entails a research observation made in regards to the smoking ban in Italy that was placed into effect January 2005. The smoking ban put into place affected smoking in public areas, such as restaurants, cafes, airports, railways, and also included the workplace (public or private). It is pointed out within the article that Italy was the fourth European nation to adopt such laws. Furthermore, the research is conducted to measure the…

I chose to focus my observational study on gender biases (between male and females) that occur during the cleanup period of a meal. The observation took place on March 27th, 2016 in my home located in Montville, NJ. After Easter lunch I observed, for thirty minutes, the “cleanup period”—the period where the table is cleaned, food is put away, and dishes, utensils, and glasses are washed. I observed twenty individuals. Eleven participants were male and nine participants were female. The age range…

MELTING POINT 65-67 °C DENSITY 1.31 g/mL HAZARDS SKIN, EYE, AND RESPIRATORY IRRITATIONS Irritation FIRE HAZARD Combustible is high temperature TABLE I: Table of physical properties and hazards of benzhydrol. PROCEDURE AND OBSERVATIONS ¬ FINDING MELTING POINT OF UNKNOWN SUBSTANCE: We used a micro spatula to retrieve unknown substance MP-14 from its jar. We placed a small amount of MP-14 on a watch glass and…
