Others Like “Runoff and Fertilizer Use”

Science Fair Project Idea
Some plants grow only in water-logged environments. These plants are usually native to wetlands and are important for the sustainability of aquatic ecosystems. Wetland ecosystems are very fragile and susceptible to the toxic dumping of sewage and fertilizer run-off from neighboring farm land. One very common aquatic plant called duckweed inhabits many wetland marshes. Duckweed grows by asexual reproduction and floats at the surface of the water with tiny roots extending into the water below.… Read more

Make your own fertile soil using kitchen scraps, manure, leaves, grass clippings, and other compostable materials. Which materials make the best compost? How does the amount of nitrogen change the rate at which the compost forms? How does traditional composting compare to worm composting, or vermiculture? How does the temperature of the compost pile change? Read more

The conversion of forested to unforested areas has been occurring since humans began to impact and change their environments during the agricultural revolution. Recently deforestation has become a global problem, particularly for developing industrial countries and countries with very large populations. You can use satellite mapping resources to investigate the connection between urbanization, population growth and deforestation. You can also investigate the connection between deforestation… Read more

When pesticides are applied to protect crops, run-off of potentially harmful pesticides is a major problem. Can water plants such as hardstem bulrush, common cattail, parrotfeather and smooth scouring rush promote pesticide breakdown? If so, diversion of irrigation run-off into plant-filled ponds could help reduce pesticide pollution. Mix malathion at 12.5% of the recommended application strength (to simulate dilution by rain or irrigation water). Use 5-gallon buckets for testing various… Read more

How much force can a rubber band withstand before breaking? Do rubber bands that stretch longer take more or less force to break? How does the elasticity of a rubber band change with temperature? Use a spring scale to measure the applied force, and a meter stick or ruler to measure the change in length. Recording with a video camera (or possibly two) can help you to capture the values at the moment before the rubber band breaks. You can change the temperature of the rubber bands using… Read more

Silt is a fine sediment that collects on the bottoms of rivers, streams and lakes. The natural process of the decay of organisms into the water can lead to the production of silt at the bottom of a lake. Silt can be a rich source of nutrients for fish and bottom dwellers like crayfish. However, it can also be introduced by unnatural processes. One problem for rivers, lakes and streams is the buildup of excess fine sediment introduced by industry. Because it often contains harmful chemicals it… Read more

It is important to ensure that we all have good clean water to drink that is not contaminated by heavy metals or chemicals. One common pollutant in a water supply is lead in old pipes or paints that can leach into the water and cause lead poisoning. There are different kits available for testing the presence of lead and other contaminants in water. Test your water supply, and also the water in some local ponds, lakes or streams. The same contaminants that can harm you can also harm wildlife. … Read more

You can investigate how the geography of an area makes it prone to severe flash floods. Some areas, typically gullies or canyons, can flood extremely rapidly making it impossible to escape a flash flood. Compare the topography, or geographical shape, or these areas. What makes them prone to flash floods? Can you do an experiment showing how the flow of water increases as a channel narrows? Can you use topological maps of your region to identify areas at risk for flash floods? (NCAR, 2006;… Read more

Can you imagine Valentine's Day or Halloween without chocolate? Well, if you're a chocolate lover brace yourself for the bad news. According to the United States Department of Agriculture (USDA), "Worldwide demand for cacao now exceeds production." If there isn't enough cacao, the major raw ingredient for chocolate, then the chocolate supply will dwindle. Hang on! Before you start rushing to the store to buy all the chocolate you can get your hands on, a solution is already in the… Read more
