Key concepts include a) the relationships among producers, consumers, and decomposers in food webs. Students gain skills in field work and identification of these critters and have the opportunity to explore and interpret trends in their data as well as data collected by others. Energy flow & primary productivity. This project will investigate how river diversions influence the living communities, food web structure, and function of created versus natural marshes to inform the development of marsh restoration strategies. In addition, the field trip is surrounded by classroom lessons that teach key concepts such as the effect of abiotic and biotic factors on stream ecosystems, food webs, and data analysis and exploration. answer choices .

Students analyze a trial involving a dispute about a composting business, then outline how a Special Investigator could gather evidence to help settle the case. This is the currently selected item. Air pollution from traffic can be a major problem in many parts of the world. When scientists do a 'budget' of a water source, it helps to think of a bank account. This video provides an overview of Dr. Polito’s project. A dataset from the Hudson River showing dissolved oxygen changes over 24 hours. Throughout the unit, students grapple with the notion that matter is neither created nor destroyed, but it takes different forms as it cycles - as part of a living thing at one point in time, then as part of the non-loving environment at another. There are different kinds of cookies with different functions: Session cookies: These are only stored on your computer during your web session. Mangrove forests are found in the intertidal zone of tropical coastlines and estuaries, commonly in the tropical coastal … The collect and display their data in appropriate graphs in order to examine the factors that influence an animal's ability to survive. Air quality refers to the health and safety of the atmosphere and is determined based on the amount of pollutants in the air. Students will collect diatom samples and compare diatom communities from their sampling site with salinity levels. Dissolved oxygen (D.O.) Freshwater marshes and wetlands provide an ideal setting to study aquatic food webs.

This brief article provides and overview of the answers to those questions. Researchers searched the following substrates within the plots: live trees, dead trees, leaf litter, and rocks. Next lesson. Students will know how to test for salt pollution in their local stream and will be able to explain whether their stream is contaminated by salt through first-hand investigations. Performance: These cookies collect information about how visitors use a site, for instance which pages visitors go to most often, and if they get error messages from web pages. Students observe soil samples, talk about where soil nutrients come from, receive a letter from a company that wants to know if dead plants can be used as fertilizer, then develop research questions. Students will know how the climate of the Hudson Valley has changed over the last 400 years and be able to explain these changes. At 12 surveyed Cape Cod salt marsh sites, 10% – 90% of creek banks experienced die-off of cordgrass in association with a highly denuded substrate and high density of crab burrows. People and cities usually don't come to mind when ecology is mentioned. Students will be able to discuss habitat needs and feeding habits of specific macroinvertebrates and understand connections that exist between the aquatic and terrestrial ecosystem. Provides a chart that students can use to remind them of the "normal" ranges for common water quality parameters. Scientists make hypotheses at the beginning of any scientific study. This is the currently selected item. What factors determine how much water plants lose through transpiration? Students will investigate whether there are more native or invasive plants and how herbivory affects both types of plants in their schoolyard. This dataset provides data on PCBs in four species of Hudson River fish collected from various locations in the Hudson over 10 years (2001-2011).
