Lab Report Assistant This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions‚ diagrams if needed‚ and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor

Oumou Fofana Period: 1 Mrs. Furlong December 19‚ 2012 Gummy Bear Lab Question- If the percent of the concentration of a solution varies‚ will the amount of water gained or lost vary in a linear fashion? Hypothesis- If the concentration of a solution varies‚ then the amount of water lost or gain will not vary in a linear fashion Prediction- I think that the amount of water lost will not vary in a linear fashion. I think the water will vary like one gummy bear would lose 4 grams while

Introduction A computerized simulation experiment will be conducted in order to study the cell transport mechanism via the cell’s selectively permeable membrane and passive processes of simple and facilitated diffusion. The plasma membrane is a gateway which allows nutrients to enter the cell and keep undesirable substances out‚ hence‚ making it selectively permeable. One method of transport is called active transport‚ which uses ATP to transport substances through the membrane. The other is

INTRODUCTION During collisions involving two bodies‚ equal and opposite forces are set up between them. These impact forces influence the subsequent motion of the bodies. Momentum of the system (consisting of both bodies) is preserved if both bodies are free to move in space. This is because there is no external forces act on the system. The forces acting between the bodies during the small interval of time when they are in contact cause changes in the velocities of each separate body. An

The Pythagorean Scale a mathematical method that is used to create all the notes of the musical scale from the harmonic series; this scale is called the Pythagorean Scale. The naturally happening harmonics are whole number multiples. To get the other notes of the scale‚ we must use fractions. The harmonic series gives us the ability to create periods of time of perfect 5ths‚ the ratio of 3/2f‚ "f" being the starting frequency. By using these 5ths‚ we can create the pythagorean scale. We can

Introduction The purpose of this lab was to identify unknown bacteria cultures using various differential tests‚ and my unknown bacteria is #17. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures. The differential

that exists from physical contact between two things. I am pulling the spring scale‚ which measure force in Newtons (kg x m/s2)‚ and then the block is moving. Different masses (kg)‚ or the measure of the resistance of an object to changes in its motion due to a force‚ of an object have different accelerations (∆v/∆t). The more massive the object is‚ the smaller its acceleration. Newton’s third law of force says that if two object interact‚ the force F12 exerted by object 1 on object

9-19-13 Dehydrating and Rehydrating a Hydrate Introduction The mass percent of water was determined using the mass of water and dividing it by the total mass of the hydrate and then multiplying that answer by 100%. The number of moles of water in a hydrate was determined by taking the mass of the water released and dividing it by the molar mass of water. The number of moles of water and the number of moles of the hydrate was used to calculate the ratio of moles of water to moles of the sample

CHEMISTRY LAB REPORTS How to Write a Lab Report Lab Reports gives the explanation of the experiment done Lab reports are an essential part of all laboratory courses and usually a significant part of your grade. If your instructor gives you an outline for how to write a lab report‚ use that. Here ’s a format for a lab report you can use if you aren ’t sure what to write or need an explanation of what to include in the different parts of the report. A lab report is how you explain what you did
