dating effect on the general public, but To-Do-It. Oil Spills. Dwight Moody. Problem. What happens when oil is spilled or dumped in safely clean up oil spills?. "Nano sand" is a product that was originally invented to help clean up oil spills in water. Since the "nano sand" is hydrophobic, it does not let water molecules. Activity. Oil spill clean up simulation. Summary: Make an oil slick with oil and cocoa powder, then attempt to clean it with a string boom and cotton ball skimmers.
Using magnets to clean up oil spills | ZDNet
By carefully recreating conditions of the plume, with water samples from the site and analyzing the microbial actors, the team discovered a new microbe. It is tentatively named Bermanella macondoprimitus because of its similarity to already identified deep-sea microbes also present within the seawater cultures produced in the lab. So now that we've discovered an oil-munching microbe — what is the big deal?
By combining knowledge of the newly discovered organism along with earlier work on microbes that degrade hydrocarbons, Anderson says scientists can now identify specific microbes that could naturally degrade oil spills in other regions of the world. Their work also offers a process for estimating how long it would take for the bacteria to consume portions of a resulting plume.The Magnetic Wand That Cleans Oil Spills: Upgrade
To put it another way, the team was able to observe the successive generations of microbes that grew, died-back, and were replaced by other microbes. This is the same sort of process that occurs when bacteria colonize your coffee makeror a bathtub that has not been cleaned in awhile.
But in this case, science now has some idea of how to predict what microbes would take charge during a deep-sea oil well blowout, and how long they might take to degrade oil and chemicals released in the spill.
One of the tar balls formed from the oil spill. This one was found on Dauphin Island, Alabama. Image via NOAA The Conditions Were Right Scientists believe the particular conditions in the Gulf of Mexico may have created a hospitable environment for hydrocarbon-eating microbes, even before the spill. One limitation of the study, and all studies to date, is the inability to model or understand the impact of the enormous natural gas release that accompanied the explosion.
Oil spill clean up simulation
While everyone hopes a catastrophe of this nature does not occur again, it is probably only a matter of time before another avoidable accident fouls the waters, the skies, or the earth. When that happens, it just may be the very smallest organisms on the planet — microbes — to the rescue. The first activity will look at the effect of an oil spill, and how we attempt to clean it up.
I will give you oil to spill in your ocean.
Show students the simulated oil: Then you will use the materials to clean up as well as we can: String models the booms that are dragged across the water to stop the oil from spreading and bring it together. Hard if there is wind on water. Cotton balls are the skimmers that stick the oil to them and pull it out of the water.
Using magnets to clean up oil spills
Last step, which we will do when you have cleaned up as much as you can, is to add a dispersant detergent. Add oil to your ocean. Your model is billion 11 zeros times smaller than the oil that was leaked into the Gulf of Mexico. The Gulf of Mexico spill was a trillion 12 zeros times larger area than your model.
How to Prep for Oil Spills: Dump , Gallons of Popcorn in the Water - Discoblog : Discoblog
It is restricted in your container - but of course is not in the ocean so spreads further. See the Gulf oil spill at https: Notice that some of your oil sinks - bitumen behaves like this, making it almost impossible to clean up.
Now try clean up: Loop the string around a patch of oil, to model how booms are spread around an oil spill.
