Electrokinetics 20-200 Monitoring over long periods Phytoextraction 5-40 Disposal of biomass The process of using plants to remove pollutants from the environment or reduce them to harmless levels is called phytoremediation. Phytoremediation deals with clean-up of organic and inorganic chemicals. There are four methods of phytoremediation that leads to decrease in pollutants: 1. rhizodegradation and phytodegradation 2. phytoextraction 3. rhizofiltration 4. phytovolatization‚ 5. phytostabilization

The refraction of light lab used common materials to examine the process of the refraction of light. The title of this lab is exactly what occurs throughout the four different experiments. All four parts of this lab use prior knowledge to observe the complex concept of refraction. Refraction is the bending of a light when it enters a medium where the speed of light is different. When light enters through the glass and water the speed of light becomes decreased. This is due to the density of water

An old‚ deaf man sits in a cafe‚ drinking late in to the night. All the other customers have left‚ and he is the sole patron remaining. Two waiters‚ one young and one older‚ sit at a table and watch him‚ sharing what they know of him through hearsay. One waiter says the old man tried to kill himself the week before. When asked why‚ the waiter says the old man was despairing over nothing‚ since he "has plenty of money." (The subject and a level of confusion in the phrasing of dialogue has been a contentious

This lab report will be detailing the steps taken and the results discovered when using spectrophotometry to determine the percentage of copper in a copper-clad penny and the thicknes of the copper layer on the copper-clad penny. After 1982‚ copper coating has been used in the creation of the penny because the cost of pure copper has increase to the point that the amount needed t omake a penny cost far more than the actual value of the penny. This lab allowed us to see just how much copper coating

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

This concept creates an opportunity to manufacture piezoelectric tiles. Re-nergy Tiles: Future of Clean & Sustainable Energy Piezoelectricity is produced by certain ceramics like quartz‚ Rochelle salt etc that generate an electric current when their material structure is misshaped.

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that
