Surface water

simulation will be performed by filling plastic cups with water, adding oil to the water to simulate an oil spill, and then participants will be given the freedom to experiment with the optimal method for removing the oil from the water or stopping it from "contaminating" other areas by using provided materials like spoons and tamper evident bands from water bottles and milk jugs. For instance, a child might decide to remove the oil from the water by scooping it out with a spoon in which case a…

boiling in NaOH and sodium bisulfite (NaHSO3) solution, neutralized with acid, washing with water and drying in the oven. Different concentration of NaOH and NaHSO3, as well as boiling time were applied for the study. Ratio fiber to liquid (w/v) was 1:20. The fibers were washed under warm tap water and then were submerged into 0.3% Hydrochloric acid (HCl) solution for 5 min, before it was rinsed with water again. The fibers were then soaked in commercial softener (3.0 g/l) with ratio of 1:10…

a rather unusual physical phenomenon where hot water freezes faster than cold water, under certain conditions. Intuitively, this doesn’t make any sense. How could water of higher temperature reach freezing temperature quicker than water of colder temperature? Water freezes when it’s molecules lose energy and slow down enough to stick together, forming ice. The molecules of water of high temperature have more energy the molecules in the colder water. So, provided the temperature of the freezer is…

1937. Luminol is highly sensitive to bloodstains or residues, even to old stains, in walls, carpets, upholstery, wooden floors, or painted surfaces. When forensic/crime scene investigators spray Luminol solution on a surface, it reacts with metal ions like iron, which are stored and transported by red blood cells. Very discrete iron concentrations on a surface, such as 1 part per million, are enough to catalyze Luminol’s chemi-luminescence (react and cause it to glow). However, Luminol…

Getting to the beach I could smell the fishy saltwater. I dove into the gigantic blue ocean, an enormous wave hits me, I was knocked to the seafloor. I could not breathe, the burning taste of saltwater went down my throat. When I finally reached the surface I was trying to catch my breath and to my shocking surprise, the massive ocean…

stay in a small or no temperature deviation environment. However, the global warming not only rises the temperature but also increases the sea level. As amphibians, toads can stay in water and land as they want. Also, El Nino and La Nina can impact toad as well. During El Nino year, higher temperature and deficient water resource cause toads to…

responsible for the outbreak. Karenia brevis (K. brevis), a marine algae, causes red tides. 2. A HAB outbreak can have an economic impact: • HAB can affect tourism, public health, jobs, public safety, and coastal communities because it can contaminate water sources used for personal use, recreational use, and fisheries. The cost of red tide nationally have been estimated to reach $50 million with public health representing $20 million, commercial fisheries averages $18 million, followed by $7…

farmers have been cutting down trees among the riverbanks and depleting the last remaining way for the soil to not get washed away with the current. Also, farming also produces waste and chemicals which also enter our water, polluting it. This then creates less pristine or foggy water for the lower parts of the river and more work for the Gold Coast City Council. However, Tourism has also left its mark upon Numinbah Valley. Through tourism, we have interfered with natural environments by…
