The Wetlands MEL

MEL Activity

There is one form of this MEL Wetlands Activity....a pre-constructed (pcMEL). The pcMEL limits student choices, which may be good for the first time the activity is introduced to a class or if you are working at earlier grade levels. Below the activity link are additional teaching resources that will help students use the Wetlands pcMEL and learn more about the competing views of wetlands.

• Wetlands pcMEL

Overview

This article provides an introduction to the Wetlands pcMEL plus suggestions from classroom use including implementation advice, insights into the lines of evidence that challenge students' thinking, and the rationale for using MEL diagrams to address socio-scientific issues that focus on value to society.

Next Generation Science Standards Performance Expectations

HS-ESS3-5: Earth and Human Activity

• Create a computational simulation to illustrate the relationship among the management of natural resources, the sustainability of human populations, and biodiversity.

HS-ESS3-4: Earth and Human Activity

• Evaluate or refine a technological solution that reduces impacts of human activities on natural systems.

Lateral Reading (LR) Resources

What does it mean for a source to be credible? Why should we investigate whether a source is credible before we read it? How do we decide whether online sources are credible? Use lateral reading to find out.

Use lateral reading to evaluate the credibility of two sources related to wetlands. Choose two from the three sources below.

This LR Activity connects to Evidence #3 above: Wetlands contribute 70 percent of global atmospheric methane from natural sources.

• Source #1: Tropical wetlands and methane - WCSSP case study

  The Met Office is the UK's national weather service provider. They provide predictions at shorter (e.g., daily weather) and longer term (e.g., climate change) scales.
• Source #2: Is climate science really real? Depends on who's behind it

  Beef is a special-interest magazine covering the international cattle industry, written to a target audience of cattle farmers and other internal business stakeholders. Published by Informa PLC, a large British publishing business.
• Source #3: The methane menace: a global environmental challenge that goes beyond cow farts

Other Resources

This Plausibility Ranking Task (PRT), which may be completed prior to using any MELs, helps students to understand the role of evidence in supporting or refuting models.

Digital Resources

This site from the EPA, Wetlands Protection and Restoration, helps individuals learn about wetlands, understand the science of wetlands, find out how the EPA, state, and tribal government efforts are protecting wetlands and how individuals can become involved in preserving this natural resource.

The National Wetlands Inventory from the U.S. FIsh and Wildlife Service hosts an online mapping tool, the Wetlands Mapper. It shows the locations of America's wetlands. It integrates digital map data along with other resources to produce current information on the status, extent, characteristics and functions of wetlands, riparian, and deepwater habitats.

What is a Wetland? defines "wetland" and provides a brief description of how NOAA classifies wetlands (e.g. ocean, estuary, river, lake, and marsh).

The USGS Wetland and Aquatic Research Center (WARC) conducts relevant and objective research, develops new approaches and technologies, and disseminates scientific information needed to understand, manage, conserve, and restore wetlands and other aquatic and coastal ecosystems and their associated plant and animal communities throughout the nation and the world.

The Status and Trends of Wetlands in the Conterminous United States 2009 to 2019 report provides the extent of wetlands in 2019, as well as changes in wetland area and type between 2009 and 2019 for the contiguous United States. It highlights the importance of wetlands in providing ecosystem services, as well as the effects of wetland loss, gain, and change in type.
