Kinetic Sand: Polydimethylsiloxane

Sand dunes act as a natural barrier against coastal storms and beach erosion caused by strong, destructive wind and waves. They are a vital part of maintaining our beaches as they absorb the impact

Sand nourishment refers to the replacement of sediment on beaches that has previously been lost, generally through natural processes. It is a commonly used practice in coastal management. Collaroy Beach uses sand nourishment as longshore drift has moved sand, which cannot be replenished as there are rock formations preventing sediment from refilling the beach. Collaroy Beach also does not have an established dune system, and cannot trap sand.

This activity is developmentally appropriate for this age group because it teaches the children many things such as weight and properties of matter. It also teaches the children the smell and texture of the sand. This activity allows them to use different things such as buckets their hands the sand and any other item they mite want to use. As a teacher I would be able to facilitate the children through out

Beach nourishment is the physical transfer of sand from an area of excess to where it is being eroded. This often involves dredging and transport of sand by truck or through pipeline. Because of the cost involved, beach nourishment is only used where other strategies prove to be ineffective.

Sand dunes are mounds of windblown sand, which vary greatly in size, from less than one meter to tens of meters high. The size depends upon the supply of sand. Many of the more recognizable dune forms are ridges or complexes of mounds or crescents. The shape of individual dunes is equally variable. Shape relates to the direction and strength of the wind forming it, as well as to the amount of sand available. The impressive sand dunes along the eastern shore of Lake Michigan were created by the prevailing westerly winds blowing the sand deposited along the beaches into the dune

You want to know how to make a peanut butter and jelly sandwitch. One of the best sandwitches on the planet. Get out all of the ingreidants. Get one plate and set it on your counter or table. You will need a knife. You can get any kind of jelly you want or like best. Same with the peanut butter and the bread. When you start you start with the bread. Grab your two slices of bread and set them beside each other on the plate. Make sure you retwist the tie on the bag of bread. Twist the lid off of the peanut butter and get some peanut butter on your knife and spread evenly across the bread until you don’t see the bread anymore. Get out your favorite type of jelly, and set it on your counter. Twist the

Help dunes to form by holding down the sand and not allowing it to blow away with the wind.

Vegetated sand ridges called dunes, built up by dry beach sand blown inland and trapped by plants and other obstructions, back most beaches. As sand accumulates, the dunes become higher and wider.

In 2014, Illinois became the first state in the country to ban exfoliating plastic beads. Plastic microbeads have been running off by the billions into the Great Lakes and the oceans, causing huge amounts of environmental damage. Yet most consumers didn't even realize they existed.

Being very dynamic communities and mobile environments, beach dunes continually moves cause the wind blows sand inland from the beach until trapped by

The diaper contains a powdery chemical absorbent, sodium polyacrylate, which can absorb over 300 times its weight. This chemical absorbs the liquid in the diaper, pulling it away from the skin. When this powder comes in contact with a liquid, its texture changes

As far as qualitative observations go, this is a great lab to see first hand the process of acquiring oil. To begin with, the oil sands were a sticky, deep-black, smooth material with a small shiny speckles throughout. After the boiling solution was added to the oil sands, the physical makeup appeared to change. As stated in Figure 1, the apparent bitumen separated from the solid sand substance that resided on the bottom. The bitumen was a shiny iridescent liquid that floated on the top and was hard to see at first, but gradually became more apparent as it got extracted. For lack of a better comparison, the process mirrored what happens to Coco Pebbles when milk is added. The leftover sand turned from a jet black to more of a gray, looked mushy and compacted, and actually resembling what appeared to be the chocolate cereal. For the most part, the hypothesis as stated before, was correct. Figure 2 clearly represents that adding 18 drops of caustic soda and raising the pH to 12, allowed for more bitumen to be separated and collected. Therefore, it is to be concluded, that the chemical reaction that the sodium hydroxide causes on the oil sands, allows for greater separation of bitumen and is a more efficient way to extraction using this method. However this pattern of applying sodium hydroxide was not allows continuous, as 12 drops resulted in the least amount of bitumen

This substance is frequently found in deep-fried foods as well as in other totally unrelated things, like silly putty, contact lenses, caulking, shampoo and conditioners, cosmetics, polishes, heat resistant tiles, and others.

After performing experiment 4-1 analysis of sand samples, the sand sample from the crime was matched with the sand sample from Panama City FL. After performing the test under the magnifying glass and looking at the sample with the naked eye, samples 1 and 3 were not it because after looking at these sample they had multiple colors in them such as black,tan and white, while the crime scene sand was only white sand. Next the microscope and polarized test samples 5 and 2 were not a match either because they appeared clear and glassy under the microscope while the crime scene with just white when it was put under microscope. The last test was the acetic acid test while confirmed the theory of the sand coming from four because the bubbling

In an event of a flood, the employees will need to work together and decide on where to move all the patients, either to higher grounds or to another facility. Sandbags and shovel will be useful to have because this will help slow down the flood of entering the hospital or area. Also, if the water if too high and the patients can no longer stay in their beds, having something that floats would be useful so patients can be pushed through that method. For the medical records, if there is any paper patient information, the records should be kept at least 24 inches off the floor and/or placed in Ziploc bags to prevent damage. Similar to if there is a fire, as the patients are being moved around, placards should be used to indicate whether the patient
