Biology Laboratory Report MEASURING RATE OF WATER UPTAKE BY A PLANT SHOOT USING A POTOMETER Introduction All plants need salts minerals‚ water‚ CO2 and O2. To fulfill their requirements different plants use different ways. Lower plants use diffusion‚ however higher plants use vascular tissue that is located in the middle of the root and in the vascular bundles in the stem. The transpiration is the important process in the plant. The main reason is that transportation

Effect of Temperature on Salt Diffusion Rates and it’s Relation to the Human Body Hypothesis: Ordinary table salt is known to dissolve easily in water. Dissolving or diffusion is the spreading of particles in another substance. This is seen when smoke from a chimney diffuses in the air around it‚ or when dropping coloring in water. When NaCl‚ sodium chloride‚ or otherwise known as ordinary table salt is combined with water the separate salt and water molecules will be attracted to each other

officially ban. Modern audiences have become accustomed to attitudes‚ language‚ and stories that are political‚ graphic‚ violent‚ and more than just a little bit avant garde. Obviously‚ such was not the case in the blacklisting days of the 1950s! “Salt of the Earth” violated every aspect of the white‚ middle-America‚ conservative mindset of 1954. As a political statement‚ it demonstrated the inter-connection that exists between working class‚ feminist‚ environmental and Latino concerns‚ and yet it

This is then reduced by means of iron powder or sodium sulphide to get para-aminophenol. The recovery of para-aminophenol is completed by dissolving the para-aminonphenol hydrochloride salt in water‚ decolourising the aqua solution and crystallising the para-aminophenol by neutralizing the salt. The resulting para-aminophenol is reacted with acetic anhydride to produce paracetamol. The reactions are summarized as shown below: Process using Paranitrochlorobenzene as a starting

The main purpose of this lab is to explain what emulsifiers and emulsions are and how emulsifiers affect emulsion stability. An emulsion is a mix of to or more liquids that usually do not mix together. One liquid is evenly dispersed in small droplets throughout the other liquid. Many emulsions contain water as one of the phases. There are two different types of emulsions. One type of emulsion contains oil droplets that are dispersed within water. It is considered oil in water emulsion. The other

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:

INTRODUCTION As for the visual documentation of a living or dead specimen‚ digital photography has largely replaced traditional illustrations of the living specimen as the standard method of recording the colour and anatomy of the specimen in the field today. Earlier traditional illustration (coloured and black and white) are still considered scientifically important because they can stress fine anatomical features that are often obscured by liquid. Even today‚ these earlier traditional illustrations

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
