Lab 3: Technology Name: Section: General Physic Lab 3 Date: 10/03/2017 Purpose The goal of this experiment was to learn how to apply computerized instruments in physics. In addition, this experiment aimed at enhancing practice on how to use three equipment in the lab: the rotary motion sensor, high resolution force sensor, and motion sensor.…
Title: Alexandra Whitaker, Ms.Dayton, 12/23/16, 2.03 lab permeability Objective(s): The main purpose is to find out if plastic bags are permeable to starch and, or, iodine. Also, to find out wither potatoes are hypotonic, hypertonic, or isotonic by testing the different amounts of sucrose solutions Introduction: The necessary background information needed for this lab is the definition of osmosis, diffusion, active transports, passive transports, permeability, concentration, tonicity, and to now the scientific concepts of hypotonic, isotonic, and hypertonic. Hypothesis: For part 1 my hypothesis is: That the starch will diffuse across the plastic bag and react with the iodine and will have a color change to the water to imply the reaction…
The materials given were three raw chicken eggs, vinegar, maple syrup, tap water, and table salt. Prior to beginning the experiment, the raw chicken eggs were saturated in vinegar for two days, in order to remove the outer shell. Also before beginning the experiment, the mass of the glass dish was obtained, via a triple beam balance, for measuring/zeroing purposes. On the day of the experiment, the three raw eggs were removed from their vinegar bath and rinsed under a stream of tap water, running from a faucet. After rinsing, each egg was patted dry, placed in a glass dish, and measured b y a triple beam balance, in order to obtain the initial mass of the egg.…

Impacts of “Kestrel storm diversion pipe” excavation and implementation: The excavation of the channel for the Kestrel storm diversion pipe will result in the temporary removal of habitable land where the channel is dug and around a small area along its length. This is assumed to be from the physical excavated hole, resulting dense and waterlogged soil which is a possible outcome of excavation as well as human presence and construction equipment. Once excavation of the first pipe begins there will be a displacement of small volumes of soil and sediment around each section of pipe. These are to be stored on site and used to fill the hole after the pipe is placed. Any excess is to be collected by trucks and transported elsewhere.…
A sinkhole turns this whole “perfect” town upside down. Tangerine is the complete opposite of perfect. Most people, like Paul’s family, come Tangerine, FL expecting it to be perfect, wanting it to be perfect, but everything was soon destroyed by a sinkhole that hit Lake Windsor Junior High. Paul is able to put aside his fear and save people, he felt like a hero.…
P1: Natural disasters have occured since the creation of the Earth and its enviornment. Sometimes they happen because it is earth’s way of releasing the stress and pressure that has been exerted onto it wether it was caused by humans or itself. Either way, these disasters can produce a multitude of negative effects towards the natural resources and life on Earth. P2:…

Discussion: Mudboils cause structural failures since they are suspensions of gravel, clay, silt and fine sand creating an unstable surface. Since the beginning of persistent mudboil activity in the 1970’s, natural landscapes and engineered features have become subject to land-subsidence as mudoils continually deteriorate the areas in their path (Tresohlavy 2003, pp. 27). Petroleum pipeline rerouting, telephone cable burials, and the collapse of bridges have demonstrated the true capabilities of mudboil persistence and destruction (Kappel & McPherson, 1998). These impacts have created a motive for truly solving the problems of mudboils within the Tully Valley. Portions of underground pipeline have become exposed due to the land subsidence issues…
How does cereal get soggy? Thousands of people around the world eat cereal with milk everyday. People eat cereal in the morning for breakfast, in the afternoon for lunch, and at night for dinner. Many people love cereal and eat the product all day long. How is cereal made?…
Quantification of Iron in Whole Grain Cereal Jacob Rickman and Yasmeen Coan Submitted to: Curt Zanelotti CHEM 1045, Experiment No. 12, April 15, 2016 LABORATORY WRITTEN REPORT Honor Code Signature: _________________ Objective In this experiment, we gained an understanding of the relationship between chemistry and food products while developing and enhancing good lab techniques. We applied dilution concepts to carry out the experiment.…
Purpose: To study sliding friction and to determine the coefficients of static and kinetic friction. Theory: Friction is a force that opposes motion. Static friction prevents an objects being set into motion by an external force. Kinetic friction opposes the progress of a sliding object.…
I. Introduction A. Have you guys heard of the different theories written about the Bermuda Triangle where pilots lost their time, direction, even their crew, and ways of communication. I wonder which theory you will believe after I finish my speech. B. The Bermuda Triangle is one of the most mysterious places in the world causing the disappearances of ships and planes without an accurate theory till today. C. Thesis Statement: The Devil 's Triangle is a mysterious phenomenon with various theories leaving everyone with a difficult time choosing which one might be true.…
