Permafrost is any soil or surface deposit in an Arctic or alpine region at some depth below the surface at which the temperature has remained below zero degrees Celsius (32 degrees Fahrenheit) continuously for a long period of time. The amount of carbon dioxide and methane stored in permafrost is nearly twice the amount in the atmosphere and, as…

There was a time when science was viewed as inherently objective, without bias. We now know that isn't true--scientists bring their life experiences and beliefs with them to work. The designing, funding, and reporting of research are all framed by societal influences and implemented by those who have been privileged to serve in these roles.…

Urban greenspaces (UGS) play an important role in the well-being of communities. With guidance from a teacher, students can be empowered to lead and design a modern UGS that supports communities and biodiversity. This lesson plan was developed with students and their communities in mind to promote awareness of the benefits of UGS between health,…

The climate justice lesson described in this article takes two to four class periods and assumes students have been introduced to the causes and effects of climate change. Using a phenomena-based teaching strategy, students are introduced to some of our most vulnerable communities around the world. They are the ones most defenseless when it comes…

Ecosystems, interacting systems of biotic and abiotic factors, are a fascinating topic in life science. The "Next Generation Science Standards" (NGSS Lead States 2013) recognize "Ecosystems: Interactions, Energy, and Dynamics" (HS-LS2) as one of four overarching ideas in life science that students should understand. Student…

It is important that students understand the role the ocean plays in mitigating climate change, and how every person on this planet is uniquely connected to the ocean. Identifying these connections can be challenging for students in rural or underserved areas, many of whom do not live by, or interact with, the ocean. Through the use of the board…

The proposed wall along the U.S.-Mexico border would significantly affect wildlife. Most animals cannot get past walls that are hundreds of miles long and many meters tall. Some species along parts of the border where a wall already exists, such as jaguars and ocelots, suffer from dwindling populations and difficulty finding mates. This column…

Students from marginalized populations may be less likely to engage in science education and form science identities. Thus, science education should include culturally responsive pedagogy to engage students from diverse cultural and ethnic backgrounds and promote science identity in every student (Mhakure and Otulaja 2017). The author is a high…

Land ethics are the ways that humanity justifies their usage of the land. Today this topic is more important than ever as we balance our needs, such as food, water, and energy, with the systems of the natural world. The activity described in this article introduces students to the concept of land ethics using historical case studies of five common…

Land use and development are complex issues rooted in ecology and environmental science as well as in politics and economics. This complexity lends itself to a problem-based learning (PBL) lesson for environmental science students. In the lesson described in this article, students investigated developing a city-owned, 13-acre site where a shopping…

Nitrogen- or phosphorus-based fertilizers, used in agriculture, can run off into nearby waterways during periods of heavy rain or high flow and cause harmful blooms (Paerl et al. 2016), low oxygen (Joyce 2000), and decreased biodiversity (Sebens 1994). Studies of the effects wetlands can have on water and habitat quality (Verhoeven and Meuleman…

After the summer nesting period, broad winged hawks are known for migrating nearly 10,000 kilometers, (6,200 miles) each fall from their breeding grounds in North America to tropical biomes in South America, where they spend the winter. The International Union for Conservation of Nature has labeled broad-winged hawks as a species of "least…

For the past 15 years, pine forests across the United States have experienced devastating mountain and southern pine beetle outbreaks (Rosner 2015). These outbreaks are not uncommon but have become increasingly severe. Due to the effects of global warming, pine beetles have been able to survive warmer winters in their native habitats, producing…

The practice of obtaining, interpreting, and contextualizing data across scientific disciplines is crucial to understanding the natural world. The authors developed the Teal Spruce sampling activity to encourage students to explore the reality of scientific data collection while also providing hands-on experience in interpreting and sharing…

Citizen science can provide insightful data to inform decisions, while also serving to enhance ecological awareness and foster environmental stewardship among participants. In this article, high school student citizen scientists investigate how trees respond to changing mountain climate during a field trip to Rocky Mountain National Park (RMNP) to…
