Systems of measurement

Part #1.- Adian and I created a carrier for two Ping-Pong balls that look like pair of glasses. To make this model we used four rectangular prisms and a cube. We used two long and skinny rectangular prisms to make the two temples of the glasses, and we used two rectangular prisms to make the two lenses. Then, we made a cube to be the bridge of the pair of glasses. We selected these shapes because when put together they resemble a pair of glasses, and we were familiar with the shapes. We also…

measuring the gravity. I found this experiment to be very interesting since I’ve seen and used pendulums a lot before, but I have never really reflected on why they oscillate. After this lab and understanding of the theory, I even know how to relate measurements to figure out the force of gravity. That is why I love physics, everything is related which makes it possible to explain phenomena seen in the everyday life.…

10/15/15: Today my experiment was approved. I plan to start on the 18th. 10/18/15: Today was the start date of my experiment. Today I performed the bulk of the procedure. First, I gathered all of the materials. Then, I put 147mL of soil in each of the cups and marked each cup. Next, I did level one (100 W) for 30 seconds in the microwave. Coming out of the microwave they were about the same temperature and texture. For level 5 (500 W), the grass seeds were in the microwave for 30 seconds and…

Basic Rhetoric Analysis of Science Fair Fun Booklet The purpose of this memo is to analyze the booklet titled Science Fair Fun, written by the United States Environmental Protection Agency’s Office of Solid Waste and Emergency Response (OSWER). This booklet will be evaluated on how it incorporates Markel’s six main characteristics of technical documentations effectively. The analysis will be written with sections categorized by the six characteristics. Summary of the Booklet The booklet,…

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…

Questionnaire-related Measurement Error Questionnaire- related measurement error could have occurred in a couple questions within our survey because of the way that the questions were worded and the possible answers that were listed. One of the questions where this occurred was in question 8 that asks, “Should the U.S. immigration laws be made stricter, looser, stay about the same, or are you uncertain?” This represents a questionnaire- related measurement error because this question does not…
