...CHEM 321 Experiment 1 Basics Review and Calibration of Volumetric Glassware There are three types of containers used in lab to contain or deliver liquids: volumetric, ordinary, and disposable glassware. Volumetric glassware are containers that have been calibrated at a specific temperature to deliver or contain VERY PRECISE amounts of liquid. Examples of volumetric glassware that we will use include burets, pipets, and volumetric flasks. Ordinary glassware has less precise volume calibrations and are used whenever the volumes do not have to be measured as accurately. Examples include beakers, Erlenmeyer flasks, and graduated cylinders. Disposable glassware (or plastic ware) is used to transfer or hold liquids temporarily and may not contain any volume markings. Examples include medicine droppers and disposable pipets. In this experiment you will be exposed to a variety of important concepts related to quantitative experimentation, including the proper use of glassware, analytical balances, and statistics. You will calibrate a volumetric pipet or flask, that is, you will experimentally determine what volume a pipet or flask really delivers. You will also calibrate a beaker or Erlenmeyer flask and a 50 mL buret. You will use these calibrated values throughout the remainder of the quarter. Construct a table at the front of your laboratory notebook to record calibration values or tape in the calibration tables from Chapter 2 of Harris’ 7th edition. How to read the level of......

...Lab 1: Measurements What is the scientific method? This week we will start with a brief discussion of the scientific method in general. This will be followed by a more detailed description of how the scientific method will be applied in this course. In the end, this discussion will give you the format for the lab reports you will write over the next 15 weeks. Our first lab will focus on taking good measurements, graphing techniques, and how to extract the important information from the data to reach a conclusion. You will be measuring round objects, so you are invited to bring different-sized round objects to class on the first day. In preparation for class, consider how round objects can be measured. 1) Brainstorm to develop the testable question. How does one measure the roundness of a round object? 2) Develop the hypothesis. Note: While the relationship in this lab is very simple and should be well known, this will not always be the case. This lab is meant to introduce the lab format without too many complications. If the diameter is increased, then the circumference is increased in a directly linear proportional manner. 3) Brainstorm for variables: The two variables that make up the testable question must be included. Identify the variables. Independent: Diameter Dependent: Circumference Control: Round objects 4) Develop the design table. | |D(cm) ...

Research Paper

...Lab Research Report SCI 110 January 27, 2014 Strayer University Lab Research Report Research in the physical sciences has often been limited by our abilities of safety observing and studying the phenomenon in question. Even before the thought of microscopes, it would have been impossible to comprehend the composition of the most basic cells. The exact issues are the current issues in the field of physical science today, but it’s particularly true in the world of physics. While new technologies exist to measure phenomenon, it is not always safe to do so in the field that deals with radiation, unstable compounds, particles and atoms. As a result, the technology that we have in the field of physics, but across the board in the physical science field of astronomy, chemistry, physics and earth science. Challenges in Measurements Over the years there have been many adventures that allow for direct measurements within the field of physics, there are still many obstacles and challenges to making direct observations. Physics is the study of energy and matter and the interaction between-both of which are impossible to observe with the naked eye. The first major challenge in making direct measurement in physics is the size of the particles being studied. To solve this issue, physicists study these particles indirectly through things like associated radiation, their energy, or the displacement of other atoms. Almost all measurements that have been made on atoms......

Intro to Physical Science

...Lab Research Report 1: Procedures in the Physical Sciences Robert Hugee Professor Brian McCann SCI110024VA016-1134-001: Introduction To Physical Science April 25, 2013 One of the underlying challenges in astronomy measurement is the determination of precise distances. Without a knowledge of its distance, the size of an observed object in space would remain nothing more than an angular diameter, and the brightness of a star could not be converted into its true radiated power, or luminosity .astronomy. (2013).  Direct measurement of the wavefunction had also long been deemed impossible because of the key tenet of the uncertainty principle. University of Rochester (2013, March 3). Getting around the uncertainty principle: Physicists make first direct measurements of polarization states of light. ScienceDaily. Large-scale surveying & mapping problems are also key challenges in making direct Measurements in astronomy. Pogge R.(2006) One of the indirect forms that the scientists have used is to resort to GEOMETRY to find the Distance. Parallax is one of the indirect methods where astronomers can measure the position of a nearby star very carefully with respect to more distant stars behind it, then measuring those distances again six months later when the Earth is on the opposite side of its orbit. Allen J.,Boyd P. (1997,April 15) The limitation of parallax is that it just gives distances to stars tp up to a few thousand light Years and beyond......

...University Physics I Lab Section: 81419 Lab Report Number: 1 Lab Title: Meaning of Measurement Name: Group Members: Date: 8/27/2014 PURPOSE: Learn the basics of measurement and statistical analysis in context of volume and density. EQUIPMENT: Three different geometric solids: 1 identified as white cylinder, 1 identified as brass-colored cylinder, 1 identified as silver-colored sphere. Meter stick (wooden, displaying measurements in cm) Analog scale (zero-ed prior to experiment) Manual caliper Digital caliper (zero-ed prior to each measurement) PRINCIPLE: This lab is intended to reinforce the importance of using proper techniques to attain precise measurements. It further demonstrates that reliability of results from different measuring devices. In this experiment, the most rudimentary measuring tool was the meter stick followed by the manual caliper and then the digital caliper. Measuring each object five times should reinforce the different interpretations of team members as well as the variance between the different tools used to measure the objects. In addition to measuring the length, width and height of each object, the mass was attained through the use of an analog scale. While a digital scale would have shown a more precise measurement, the analog scale was a more appropriate tool with the meter stick and manual caliper as the significant figures produced by each are more comparable. After measurements are taken, the......

How to Titrate a Solution

...Telicia Peet ENG 231 3/15/2014 How to Titrate a Solution A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution (ChemMed). In a titration a solution of a known solute (titrant) is added to a solution with an unknown solute (analyte). The chemical composition of a substance is very intricate, and learning how to titrate a solution is the most fundamental step toward determining the chemical makeup of that substance”. When a substance becomes synthesized, it is important to know that it has the chemical makeup expected. The point at which the solutions meet is known as the equivalence point; here the amounts of the two substances are stoichiometrically equivalent. The endpoint is the point at which the titration is complete (Princeton). There are numerous ways to determine the composition and structure of a substance, yet this manual demonstrates how to titrate a solution. To conduct this experiment, he or she will need a burette, an Erlenmeyer flask, a lab coat, goggles, and an unknown solution to titrate. Typically this is done in a laboratory but anywhere with an ample amount of space is fine. The burette is used to dispense accurate volumes of a substance. Attached to the burette is a stopcock that is used to release or withhold a substance. Normally the titrated solution is purple, but the color of the titrant may vary also. An Erlenmeyer flask is a piece of glassware used to pour the......

Written and edited by: Karon Felten and Nutrition 121 TA’s With Special Thanks to: Chris Pritsos Ph.D. Nutrition Department Chairman ABSTRACT: In nutrition, there are many factors that influence an individual’s health and body weight, such as heredity, food selection, eating behaviors, and physical activity. Scale weight is not always a good indicator of body fat, lean mass, body water or overall health (1). This laboratory experience will give students the opportunity to conduct physical assessments by evaluating body weight and body composition. To determine body weight and body composition, techniques such as bioelectrical impedance analysis (BIA), body mass index (BMI), waist circumference, wrist circumference for determining frame size, and a scale will be utilized. Students will also evaluate their own risk for cardiovascular disease and assess cardiovascular health in volunteers by measuring heart rate, filling out a heart disease risk score form, and estimating oxygen consumption and energy expenditure through a technique known as the Queens College Three-Minute Step Test. BACKGROUND: Your body is made up of the six essential nutrients: water, fat, protein, carbohydrates and various vitamins and minerals. Many factors can influence an......

...not received any anticoagulation medications and proper technique is followed, hemostasis can be achieved for venous sheaths smaller than 9F in about 5 minutes. For arterial sheaths of 4F or 5F, hemostasis may be achieved in less than 10 minutes; for 6F to 8F, 10–15 minutes of manual compression is generally sufficient. If arterial sheaths of 9F or greater are used, compression time will need to be adjusted accordingly (Watson, & Gorski, 2011). Problems associated with manual pressure for hemostasis include poor technique such as staff fatigue, inconsistent pressure, and tendency to carpal tunnel syndrome related to hand and wrist strain. Alternative use of C-clamps or FemoStop can relieve the manual strain associated with holding the femoral site for extended lengths of time (Watson, & Gorski, 2011).

Even with the tools that exist it is not always possible to safely do in a field that deals with atoms, particles, radiation, and unstable compounds. The technology in the area of physical science makes it very important on how much is learned and studied in the fields of astronomy, chemistry, physics and even earth sciences. There have been many advances that allow for direct measurements in the field of physics, there are many obstacles and challenges to making direct observations in many circumstances. Physics is the study of energy, matter and the interaction between the two, which are impossible to observe with the naked eye. One common thing the field studies is energy creation to non-particles, all of the most recent discoveries in subatomic particles and the origins of the universe have all creative methods to study things that are extremely tiny. This would be the first major challenge to making direct measurements in physics. To avoid this problem, physicist usually studies these particles indirectly through things like associated radiation, energy, or the displacement of other atoms and/or compounds.
