Estimation of Duckweed Geometric Population Density Phosphate Depletion By Ana Rosina Alarcon University of Texas at El Paso Department of Environmental Science Instructor: Gebregiorgis Alay G. Introduction Duckweed is a small aquatic plant that is able to grow rapidly‚ making it the ideal specimen for our experiment. It is hypothesized that altering the amount of light received by duckweed will alter its photosynthetic rate. It is predicted that a lower light intensity will

Although the reproduction of harmful bacteria may be hazardous‚ it is necessary for microbiologists to grow high populations of bacteria in the attempt to study the causes and provide prevention methods for spreading harmful bacterium. The purpose of this lab was to collect and observe microorganisms from the environment and the human body and placing into the appropriate media using aseptic transfer techniques. The necessity and value of collecting‚ identifying and analyzing is critical for learning how

Science: Investigating the best fabric for science laboratory clothing. (Final Report) Abstract: This experiment looked at the effectiveness of cotton‚ wool and polyester to come up with a hypothesis to which material would be the best used in a lab coat. After the hypothesis was made an experiment was done on the 3 materials‚ to find out which material is the best to use in a lab coat. The results of the experiment were that wool was the best material to be used in a lab coat. Introduction:
