Climate change is a critical scientific and social issue of our time, yet the topic is not frequently discussed by the general public. Additionally, misconceptions about the topic persist. One important aspect of climate change is the greenhouse effect. This activity adds a greenhouse gas discussion to an existing module about molecular shape and…

Water is critical to our health and well-being, yet one in three people do not have access to safe drinking water. Earth's water is threatened by pollution, deforestation, urban growth, and climate changes. This article describes a unit for kindergarten children called The Water We Drink.

A laboratory experiment was designed and implemented in a STEM teaching laboratory at Michigan State University to engage students in an activity that not only introduced an innovative nitrate detection technique but also addressed one of the negative impacts of climate change, that is, the eutrophication of water bodies. The adverse effects of…

In this laboratory experiment, students explore the aquatic photochemical fate of ranitidine and cimetidine, two common pharmaceutical pollutants found in wastewater. It provides an engaging environmental context for students to develop knowledge of reaction kinetics and photochemistry as well as skill in using analytical instrumentation. This…

Understanding how to interpret and manipulate large data sets is increasingly important today; however, this experience has been slow to trickle down to the typical undergraduate student. Here, we describe the implementation of a project-based learning experience that uses portable air sensors for the real-time measurement of carbon dioxide,…

The joint virtual global learning activity brought together college students from Jordan and New York City to learn about United Nations Sustainable Development Goal (UN SDG) #6 and explore the issues of water pollution and drinking water quality in both regions. The activity involved undergraduate students from Guttman Community College and…

This column contains exercises to challenge content knowledge. This month's issue discusses ways to remove CO[subscript 2] from the atmosphere.

This article describes how fifth grade students participated in a place-based environmental education initiative in West Michigan that supports teachers who want to involve their students in citizen science by protecting local water resources. Every year, Groundswell works with about 100 teachers at 30 schools to engage students in citizen science…

The lichen is an ideal subject for student study because it is omnipresent in school yards, easily collected and observed year-round, a pioneer of evolution on land, and a bioindicator of air pollution. After doing fieldwork on this unusual composite organism as an apprentice with a team of lichenologists, Sarah Thorne developed Learning Lichens.…

Groundwater contamination is a serious environmental problem, given that all living things depend on this essential resource. Groundwater represents less than 1% of all water found on Earth, but nearly 90% of the freshwater used comes from groundwater (USGS 2016). The problem-based activity described in this article actively engages students in…

This article describes a five-day online energy module, developed by the Concord Consortium (an educational research and development organization) in which students compare the effects of various energy sources on air quality, water quality, and land use. The module's interactive models explore hydraulic fracturing, real-world data on energy…

Across the United States, political leaders, educators, and business persons are issuing an urgent call for reform in STEM education (NGSS Lead States 2013). One important response to this call is Integrated STEM, which the National Governor's Association (2007, p. 7) says involves, "... an emphasis on design and problem solving in…

For students in biology, chemistry, or environmental science, diatoms offer excellent insight into watershed health and human impact on the environment. Diatoms are found globally in virtually every habitat that has sunlight and moisture, including polar seas, tropical streams, and on moist soils and mosses. Studying diatoms as biological…

Roadways are literally soaked with petrochemical byproducts, oils, gasoline, and other volatile substances that eventually run off into sewers and end up in rivers, waterways, and other undesirable places. Can the roads be cleaned of these wastes, with their proper disposal? Can vehicles, robots, or other devices be designed that could be driven…

Pollution is not a problem we just read about anymore. It affects the air we breathe, the land we live on, and the water we consume. After noticing a lack of awareness in students, a lesson was developed that used Google Earth to pinpoint sources of pollution in the local area and in others across the country, and their effects on the surrounding…
