EXPERIMENT 2: SUSPENDED SOLIDS 1.0 OBJECTIVE This objective of this experiment is to determine the quantity of suspended solids in polluted water samples. 2.0 INTRODUCTION Water quality is vitally important in our daily life. However‚ due to water pollution‚ the quality of water is questionable for safe usage. In order to determine water quality‚ one of the indicator and measurement that can be used is by suspended solids (SS). Suspended solids is one type of physical water-quality measurement

Organic Chemistry I Simple and Fractional Distillation The Simple and Fractional distillation experiment was divided into two parts. We split up the procedure in this experiment. My group did the simple distillation and we received the Fractional distillation from another group in class. In this experiment‚ we examined the effectiveness of fractional and simple distillation to determine which is more successful at extracting a pure sample. This experiment was very successful. We are able to

Meselson–Stahl experiment From Wikipedia‚ the free encyclopedia The Meselson–Stahl experiment was an experiment by Matthew Meselson and Franklin Stahl in 1958 which supported the hypothesis that DNA replication was semiconservative. In semiconservative replication‚ when the double stranded DNA helix is replicated each of the two new double-stranded DNA helices consisted of one strand from the original helix and one newly synthesized. It has been called "the most beautiful experiment in biology.[1]"

Doctors for these camps came in all shapes and sizes including former S.S. Troops‚ Women‚ and a variety of prisoner doctors. The experiments differed as much as the doctors themselves; however they stayed the same in one factor‚ medical curiosity become killing in atrocious

Technology based laboratory to improve science learning Abstract Till date‚ manual routine devices and methods are used to perform different test strategies in the greater part of the science research centers in our nation. The manual instruments are cumbersome though the robotized ones are expensive. It does not enthuse youthful analysts towards the science laboratories. There is a need to create applications which can be easily integrated‚ customized in school and undergrad level laboratories and are prudent
