spectrophotometer measured for absorbance‚ which was used to calculate initial cell density. The caps on each of the samples were then loosened to allow movement of gas in and out of the tube. After a week of growth under fluorescent lighting‚ the tubes were inverted for mixing and measured for absorbance again. The values were used to calculated the corresponding final cell density. The calculations of initial and final density of cells were used to determine the algal growth rate of cells per milliliter

Be Specific The sun was shining on the flower in the window‚ no‚ wait‚ scratch that. The summer sun was shining on the pink rose sitting on the windowsill. Now doesn’t that sound better? Natalie Goldberg believes people should be specific. It paints a vivid picture when we do. Buying a book of the names of plants and flowers in her environment was her start to feeling ore connected and grounded to our Earth.

Anxiety Lab Report Abstract: The aim of this study is to investigate the relationship between cognitive anxiety‚ somatic anxiety and self confidence in two different situations; non-stressful and stressful. It is to examine the effects on anxiety of a simple golf putting task. The stressor used in this experiment can be described as situational‚ namely the stressor of social comparison‚ the type of stressor that leads many performers to question their own ability which in turn evokes symptoms

Physics Lab Report Format General Remarks: Writing a lab report is the only way your TA will know what you have done during the lab and how well you have understood the process and the results. Part of your lab experience should be learning how to organize and present your work in a scientific way. There is no framework that can be used as a “one size fits all”‚ therefore this sample lab report should only be used as an example. Any lab report should have the following features:

Engineering Laboratory (Lab) Report Department of Engineering Faculty of Engineering and Science‚ University Tunku Abdul Rahman (UTAR) 1. Introduction Laboratory (Lab) reports are the most frequent document written by engineering student. These reports can contribute a significant amount of marks and yet little time or attention is devoted in understanding on how to write them well. The aim of this document is to provide a general guideline on writing a lab report. A lab report should not be

Introduction The aims of the lab session was to familiarize with the principles‚ operation and application of a light spectrophotometer. This report discusses an experiment to study the relationship of absorbance and concentration‚ the interaction of electromagnetic radiant energy(ERE) and matter which is an important aspect of the Beer-Lambert ’s Law. This law states that the absorption of a compound is directly proportional to the concentration of that particular compound. This is because (a &
