Purpose: During our lab‚ Galileo’s Water Clock‚ we created our lab to describe the motion of a ball on a plane using the water clock as an alternative method for measuring time. Our main purpose in this lab was to determine if the displacement of the ball is determined by the time or the time squared. Procedure: Once the water clock was set up‚ a ball was let go from the ramp at various distances for three trials each. Once the ball was let go‚ the water clamp was opened and then immediately

In the article “Houston Flood Waters Are Tainted With Bacteria And Toxins‚ Tests Show” by Sheila Kaplan and Jack Healy‚ flood waters in Houston neighborhoods have been contaminated. Plus‚ the spread of the toxic waters is not clear on how far they have gone‚ but it is hinted that the breaches of several waste plants have made the waters more dangerous. Testing has occurred and has found traces of Escherichia coli which is a fecal contamination. In the Clayton Homes public housing development‚ high

Aracely Arzola Contaminations We were only gifted with one Earth so it’s up to us to take care of it and make sure environment remains beautiful and full of life. Contamination is a big threat that Earth faces today because it pollutes our environment and destroys it little by little. All the waste‚ smoke and trash have to come to an end because they pose a menace to the purity of our ecosystem. We find all that we need for life from water to plants and air in our environment.

Topic 6 Water Quality and Water Management What determines water quality? Drinking water should be colorless‚ odorless and flavorless; this means that there are no organisms and sediments in the water‚ but it does not mean that if your drinking water look‚ smells and taste clean‚ that does not mean that there is nothing else it. Water also contains dissolved solids: •Sulfur •Calcium •Magnesium If water contains a lot of dissolved calcium and magnesium it is called hard water

Noah tries to prove his dad right by exposing the ship for flushing human waste to the ocean. The author‚ Carl Hiaasen is famous for writing books that are all about environmental problems in Florida. Specifically‚ this book is about water contamination. Water contamination is a big problem in Florida. I really enjoyed the book because it was realistic and interesting. It was very funny and kept me wanting to read more. I really liked many things in the book but probably my favorite was the characters

Percent Water in a Hydrate PURPOSE To determine the percent water in a hydrate sample. INTRODUCTION Many substances contain water molecules as a part of their crystal structure. We call such solids hydrates‚ and we call the bound water the water of hydration. A hydrate has a definite number of water molecules bound to each anhydrous salt unit. The formula of the hydrate copper(II) sulfate pentahydrate is CuSO4 · 5 H2O The dot indicates that the molecules of water are attached to the ions in
