Lab Report 1: Measurement Lab Date: January 17‚20XX Lab Partners: XZ Report Date: January 24‚2014 Report Written by: XXXXXX Introduction: Measurement is a form of quantitative observation. The ability to make accurate and precise quantitative observations is crucial to science. Accuracy in this sense refers to the closeness of the measured result to the hypothetical “true” value (Motzny 2014). Having a precise measurement implies its exactness.

Basic Lab Measurements and Equipment Purpose This lab experiment displays the accuracy of scientific measuring equipment. This experiment also helps to familiarize the students with these instruments. Procedure: Measure Volumes and Masses 1. Obtain a 400mL beaker and record its mass in grams. 2. Add 40mL of water to the beaker and record the volume. 3. Records the beaker’s mass now with the added water 4. Transfer the water from the beaker to a 50mL graduated cylinder and record the measurement

Explain TWO precautions that the learners must take to ensure that the results are reliable. In the investigation on transpiration‚ measurements of the distance travelled by the air bubble in the capillary tube were taken every minute. The opening of the capillary tube had an area of 4 mm2. Study the table below of the results obtained‚ and answer the questions that follow. Time (minutes)

was laboratory techniques and measurements. The purpose of this lab was to familiarize ourselves with different techniques used in the lab‚ taking proper measurements‚ and how to use the International System of Units (SI). Throughout lab we learned about mas‚ volume‚ length and temperature‚ and to be able determine density and concentration. To be able to documents properly and make effective observations we must be able to understand the International Measurement System. Length‚ temperature‚ time

Refractive index measurement is actually a measurement of the speed of light in a medium. The speed of light (usually denoted by c) is 299 792 458 m/s in vacuum. In other media the speed of light is lower than this value‚ and the refractive index‚ R.I.‚ of a medium is a measure of how much the speed of light is reduced in the medium. The refractive index (n) of a medium is defined as the ratio of speed of light in vacuum (c) in to that in the medium (v) The speed of light in a medium depends on

ARCELIA ARRATIA MEASUREMENT OF LENGTH‚ MASS‚ VOLUME‚ AND DENSITY PHYSICS LAB REPORT Physics is the scientific study of matter and energy and how they interact with each other. Physics utilizes the scientific formula to test hypothesis and calculate matter such as density. Tools were created to measure material in a laboratory and have been perfected to reduce error. In this experiment measurement of length‚ mass‚ volume and density will be obtained through instruments of measuring

Title: Laboratory Techniques & Measurements Purpose: To become familiar with the International System of Units and common laboratory equipment and techniques. To learn how to determine volume‚ mass‚ length‚ and temperature of a wide variety of items. To learn how to calculate density and concentration of dilutions. Procedure: I used a ruler‚ thermometer‚ and scale to take measurements. I used a graduated cylinder‚ short step pipet‚ scale‚ and ruler to determine volume and density. I used a

This can be measured when we perform our observations. By measuring a patient’s respiratory rate‚ oxygen saturations‚ peak flow (in asthma patients)‚ pulse rate‚ systolic and diastolic blood pressure‚ core temperature‚ blood sugar‚ pupil reaction and Glasgow coma scale. All these combined measurement can give us an insight into the patient’s

Laboratory Measurements and Density Objectives: A. To determine the density of Aluminum (lit. value = 2.7 g/cm3) by determining its mass‚ and measuring its volume by dimensional analysis and water displacement. We will also examine the % error in our determination based on the literature value. B. To determine the mass and diameter of select ball bearing. Plot graphs of mass vs. diameter‚ mass vs. surface area‚ and mass vs. volume. Afterwards use slop of the mass vs. volume graph to determine density
