Waste Water Treatment Samuel Rodriguez May 29th‚ 2013 Abstract: In this lab‚ we were introduced into the steps that the San Diego Water Treatment plant does to clean and filter that water that goes into millions of homes in San Diego. The purpose of this lab was to correctly follow the safety procedures that the San Diego Public Utilities Water and Wastewater plant have to follow so that we can raise our awareness of our own backyard‚ our own streets‚ our own oceans‚ and our own world

Water lab Research Question: How many drops of water can fit on a coin? (Water properties involved are cohesion and surface tension. Cohesion plays a consequential role in the transport of water within plants specifically within the phloem. Surface tension also dictates an important role within the transpirational pull of the xylem.) Variables: Variables | Type of Variable | How it was manipulated | Independent | Water drops‚ different types of water | Determining how many drops of the

Plop Plop Fizz Fizz Expt # 1 I. INTRODUCTION: In this lab I will try to see in what an Alka-Seltzer tablet will dissolve fastest in. I need to figure out if the Alka-Seltzer tablet will dissolve slowest or fastest in tap water‚ warm water‚ cold water‚ salt water‚ or acidic water. In this lab I wall develop and test a hypothesis‚ analyze data and draw a conclusion. In this experiment I will find out that in a type of water the Alka-Seltzer will dissolve faster and slower. Alka-Seltzer is

of Earth’s land animals and plants live in forests‚ and many cannot survive the deforestation that destroys their homes (National Geographic‚ 2015). The forests are the home to a large number of animals; trees are also an important component of the water cycle (Bose‚ 2012). The roots of trees hold the soil together and prevent soil erosion. Deforestation at such alarming rate has been a cause of constant worries for environmentalists the world over (Bose‚ 2012). In some developing countries‚ massive

My Science Project Can water float on water? My Prediction I predict that water can’t float on top of water. Simply because it sounds impossible‚ but it will be interesting to find out if however it is possible. The Experiment First‚ I found two 1litre bottles and marked one with ‘+ salt’ and the other with ‘fresh’. I then went on to add red food colouring to the fresh bottle and yellow to the + salt bottle. The reason for doing so was to establish which ones were which and see if they

2015 Daphnia Lab Results Paper Abstract The goal of the study was to observe the effects of multiple chemicals on a Daphnia magna’s heart-rate compared to a control (pond water). The different chemicals were caffeine and alcohol. The heart-rate was the main variable in this experiment. The Daphnia’s heart-rate was observed for 15 seconds and then multiplied by 4 to show its heart-rate in one minute. This was repeated 4 times for each chemical. The data was averaged at the conclusion. It was discovered

Water Pollution Water pollution is the contamination of bodies of water such as ponds‚ lakes‚ oceans‚ rivers and even groundwater. Water pollution is mainly caused by many human activities‚ which can be harmful to animals and plants which live in these bodies of water are located. Nature also takes its toll on water pollution such as volcanoes‚ severe storms‚ and earthquakes also cause major changes in the quality of water. Water is typically considered to be polluted when it’s impaired

Seperatation Technqiues of Sand/Salt/Water Mixture Most of the material that are encountered in everyday life are not pure substances. Materials ranging from cement‚ food and ink are formed from physical combinations of various substances called mixtures. A mixture is a type of material that consists of two or more different substances that are not chemically combined. All mixtures can be separated back into its original state except for those that undergo irreversible change. A mixture can take
