Science Buddies participates in affiliate programs with In the coastal areas of the western United States, soils have higher levels of nitrogen, which feed nonnative grasses. In the San Francisco Bay Delta, for example, blue-green algae blooms occur in numbers during the warmer months, especially when the conditions such as increased nitrogen occur, according to the California Department of Health. ... Nitrogen and phosphorus compounds from fertilizers are among the most common pollutants. Swedish chemist, Carl Wilhelm Scheele was a fan of phlogiston too and probably discovered oxygen before Priestly did. The amount used typically depends on plant and seed instructions as well as on the other sources of nitrogen, such as manure, already applied to the soil. Graph you results, with the growth on the y-axis and the time on the x-axis. Reproduction of material from this website without written permission is strictly prohibited. Researchers at the Woods Hole Oceanographic Institution say these algae blooms, which can appear in different colors, produce toxins that can be harmful. Other plants that have lower nitrogen needs end up dying, causing a decline in native species, according to the Ecological Society of America. 2018-01-07 23:01:40, What was the most important thing you learned? What are sources of nitrogen and phosphorus pollution in freshwater? High, Compared to a typical science class, please tell us how much you learned doing this project. Moss is Boss: Using Plants to Determine Direction. These kits can be ordered from science supply stores such as. (2020, November 20). These kits are easy to use and will add an extra level of analysis to your project. Live algae and nitrate- and phosphate-containing chemicals can be ordered from science supply companies, such as. Transfer 200 mL from the cup labeled 0.06X to a sink or other disposal area. Place the algae cultures in a spot indoors that is well-lit during daylight hours. Try one of our science activities for quick, anytime science explorations. Grow algae in several concentrations of fertilizer and observe its effect on algal growth. Produce and sell corn, grains, hemp, barley, and more. Home Science Tools, A soluble substance, nitrogen soaks deeply into the soil after a rainstorm or after irrigation, reaching ground water and nearby wells. Manage pests, weeds and diseases, and improve soil quality. When these organisms die, the decomposition process then depletes oxygen in the water, killing fish and other aquatic life. the water i collected from a river source was not that clean, Can you suggest any improvements or ideas? The perfect thing to liven up a rainy day, school vacation, or moment of boredom. It is abundant, multivalent and nonmetallic.Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S 8.Elemental sulfur is a bright yellow, crystalline solid at room temperature. Have an adult come along to help. In California, for example, the National Science and Technology Council reports that too much nitrogen encourages the growth of nonnative grasses and kills off lichens on trees. Record the value, 1 to 5, for the amount of growth each day for each culture. Sulfur is the tenth most common element by mass in the universe, … About the same. Please log in (or create a free account) to let us know how things went. Write to us at. Performing the procedure several times shows that your results are repeatable. Naturally, knowing the original nitrate concentration in the water is important. Carolina Biological, and I actually like what you’ve acquired here, really like what you are saying and the way in which you say it. Ecological Society of America: Excess Nitrogen in the U.S. Based on your research, what organisms produce nitrates as part of the. Mix the contents in the cup with a clean plastic spoon. Unfortunately, remaining nitrate-nitrogen may still result in drinking water that exceeds the standards of 10 mg/l nitrate-nitrogen. If nitrate-nitrogen levels are extremely high (greater than 110 mg/l) up to 90 percent may be removed. Pond Algae Control Products ; ... the National Science and Technology Council reports that too much nitrogen encourages the growth of nonnative grasses and kills off lichens on trees. The shift in plant species increases the chances of wildfires because these new grasses are flammable, the ESA explains. For any other use, please contact Science Buddies. Make a data table in your lab notebook listing the concentrations of fertilizer in each cup and the amount of algae growth. These symptoms result from the condition methemoglobinemia, also called "blue baby syndrome," which occurs when nitrates mix with iron in red blood cells, leaving the blood unable to transport oxygen to the body's cells. Science Buddies, a 501(c)(3) public charity, and keep our resources free for everyone. Write to us at Copyright © 2002-2021 Science Buddies. Sulfur (in British English: sulphur) is a chemical element with the symbol S and atomic number 16. Find information from Penn State Extension about agronomic crops. What is your enthusiasm for science after doing your project? This is actually a tremendous website. Phosphate (PO4), which plays major roles in the formation of DNA, cellular energy, and cell membranes (and plant cell walls). just too great. © Copyright 2020 Hearst Communications, Inc. scibuddy@sciencebuddies.org. We depend on fresh water from lakes, rivers, and reservoirs for drinking, as well as for recreational activities, such as swimming, boating, and fishing. Science Buddies Staff. Nitrogen and phosphorus compounds from fertilizers are among the most common pollutants. Phosphorus is also often present in fertilizers in the form of phosphate. Determine the concentration of the fertilizer chemicals in your dilutions based on label information. Therefore, it is important to consider means to prevent or reduce the amount of fertilizer that finds its way into natural bodies of fresh water when considering ways to deliver fertilizer to crops and lawns. The remaining "control" cup should not have any fertilizer. Eutrophication (from Greek eutrophos, "well-nourished"), is a limnological term for the process by which a body of water becomes progressively enriched with minerals and nutrients.Water bodies with very low nutrient levels are termed oligotrophic and those with moderate nutrient levels are termed mesotrophic.Eutrophication may also be referred to as dystrophication or … Jameco Electronics. In January 2013, the California State Water Resources Control Board reported that more than 400 private wells and more than 200 water systems in the state were contaminated with nitrates. Wikipedia Contributors. To obtain quantitative measurements of the algae growth, consider the methods in this Science Buddies science fair project: Design a procedure using a single species of algae and precise amounts of nitrates and phosphates. This process uses up oxygen, causing levels to drop. Nitrate. Nitrogen in the form of nitrates works very well as a plant fertilizer and is produced in large quantities for this purpose. Her articles have appeared in the "Daily Press," "The Packer" and "Indian Country Today." This type of pond is usually called a “wildlife” pond, and is kept healthy with natural bacteria, plants, and a strong nitrogen cycle which will benefit from added aeration and oxygen. In this environmental science fair project, you will investigate the effect of varying concentrations of fertilizers on the growth of freshwater algae. It is obviously of critical importance to keep sources of fresh water as clean and unpolluted as possible. (2009, October 24). Mix the contents of the 0.06X cup with a clean plastic spoon.
