In this activity, students are introduced to tree rings by examining a cross section of a tree, also known as a 'tree cookie.' They discover how tree age can be determined by studying the rings and how ring thickness can be used to deduce times of optimal growing conditions. Next, they investigate simulated tree rings applying the scientific method to explore how climatic conditions varied over time.

This video focuses on the conifer forest in Alaska to explore the carbon cycle and how the forest responds to rising atmospheric carbon dioxide. Topics addressed in the video include wildfires, reflectivity, and the role of permafrost in the global carbon cycle.

Increasingly volatile climate and weather; vulnerable drinking water supplies; shrinking wildlife habitats; widespread deforestation due to energy and food production. These are examples of environmental challenges that are of critical importance in our world, both in far away places and close to home, and are particularly well suited to inquiry using geographic information systems. In GEOG 487 you will explore topics like these and learn about data and spatial analysis techniques commonly employed in environmental applications. After taking this course you will be equipped with relevant analytical approaches and tools that you can readily apply to your own environmental contexts.

The forests of North America have seen plenty of change in a pretty short period of time, at least geologically speaking. Up until about 18,000 years ago, the Laurentide Ice Sheet covered Canada and much of the eastern United States. When temperatures climbed and the ice sheet retreated, forests gradually reemerged. But how? Did pockets of trees find refuge in sheltered areas during the Ice Age? Or were all tree species pushed to the southern tier of the United States, only to spread north again after the ice disappeared? Scientists still debate the topic, but one thing is clear: today’s forests in the eastern United States bear little resemblance to post-glacial forests. Starting with European colonial settlers and marching through four centuries of development, drought, and fire, the tree cover of North America became fragmented.

Trees grow all around us. Sometimes they are in large forests and sometimes they are single trees along the road or in our schoolyards. In this storyline, students explore cultural connections with trees, learn about the characteristics of trees, and discover what trees need to grow through handson activities, art, and literacy integration.

El objetivo del caso de quinto grado, Bosques: Beneficios del ecosistema forestal, es aprovechar el conocimiento previo de los estudiantes sobre las necesidades de las plantas / animales, los ecosistemas y la protección de los recursos de la Tierra. En este caso, los estudiantes desarrollan una comprensión de los ecosistemas forestales, los beneficios de los árboles, incluyendo la captura de carbono, y lo que los árboles necesitan para crecer/ agregar masa. 

Students will learn how trees grow and cycle matter, and trees’ roles in a changing climate. The urban heat island effect is examined and students learn about the many benefits trees offer cities. The storyline culminates with students examining the trees and canopy cover in their or a nearby city and proposing actions to increase the urban forest through a letter to city officials.

El objetivo del caso de la captura del carbono en los bosques a nivel escuela preparatoria es basarse en la ciencia de la captura de carbono del caso de la escuela secundaria. En este caso, la captura de carbono se refiere a la eliminación de carbono (en forma de dióxido de carbono) de la atmósfera a través del proceso de fotosíntesis. El almacenamiento de carbono se refiere a la cantidad de carbono unido al material leñoso por encima y por debajo del suelo. Los estudiantes de preparatoria desarrollarán una comprensión de las variables y consideraciones que surgen del manejo de los bosques para diferentes propósitos, incluida la captura o secuestro de carbono y otros servicios del ecosistema. 

This is a solutions-oriented storyline that leads students through a series of investigations to quantify and qualify the ecosystem and social benefits of an urban forest. At the end of the storyline, students will be able to design, evaluate and refine a chosen solution for urban forest ecosystem benefits.

Los estudiantes exploran el fenómeno de cómo un árbol obtiene su masa. Se les anima a pensar en lo que saben sobre la fotosíntesis y explicar lo que saben y lo que se preguntan sobre el fenómeno de una semilla que se transforma en un árbol grande y tiene masa. Específicamente, el carbono se absorbe de la atmósfera en forma de CO2 y se transforma en glucosa para proporcionar energía y, en última instancia, material de construcción (celulosa). En este caso, la captura de carbono se refiere a la eliminación de carbono (en la forma de dióxido de carbono) de la atmósfera a través del proceso de fotosíntesis. El almacenamiento de carbono se refiere a la cantidad de carbono unido al material leñoso por encima y por debajo del suelo.  

Urban forests provide many benefits to a community and can minimize the human impact on the environment. Students will explore the impacts an urban community has on the environment. Students will discover the role trees play in an urban community and how trees can affect the ecosystem, human wellbeing, and provide economic value. Students will explore Indigenous relationships with trees. During the course of this storyline, students will measure and monitor urban forest ecosystem benefits, perform a field investigation, and design a development to minimize negative environmental impacts

Dr. Steve Running, a Regents Professor in the College of Forestry and Conservation at the University of Montana, discusses the paradox of why forests in the West are growing faster while simultaneously suffering from higher die-off rates. Running is a member of the Nobel Peace Prize-winning Intergovernmental Panel on Climate Change and was the lead author on a 2007 report analyzing North AmericaŐs contribution to atmospheric carbon dioxide and its impacts on the global climate.

This video segment from NatureScene describes the characteristics of redwood trees at Redwood National Park.

In this two̢ hour program, Jean Michel Cousteau and the Ocean Adventures team visit the Amazon River Basin. The mighty Amazon River flows through the world̢ĺŰĺŞs largest tropical rainforest, creating the most biodiverse area on the planet. Twenty̢ five years ago, Jean Michel explored this fabled region with his father, Jacques Cousteau. Since then, an area the size of Texas has been deforested. From this region of urgency and conflict - where human enterprise and expansion not only compromise the health and ecology of the river and rainforest basin, but also truly inflict consequences on a global scale - come new beacons of hope and sustainability.€âĺ_n acest program de douĚăĺÄ ore, Jean Michel Cousteau €_ĺŮi echipa Ocean Aventurile viziteazĚăĺÄ bazinul r€âč÷ului Amazon.

In this hands-on activity, students will learn about dendrochronology (the study of tree rings to understand ecological conditions in the recent past) and come up with conclusions as to what possible climatic conditions might affect tree growth in their region. Students determine the average age of the trees in their schoolyard, investigate any years of poor growth, and draw conclusions about the reasons for those years.

This activity describes the flow of carbon in the environment and focuses on how much carbon is stored in trees. It goes on to have students analyze data and make calculations about the amount of carbon stored in a set of trees at three sites in a wooded area that were to be cut down to build a college dormitory.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Tropical ecosystems can transition between forest and savanna but how these transitions are affected by changing rainfall patterns remains uncertain Climate changes interact with local grazing and wildfires to determine the growth of tropical trees and grasses A new study looks at how feedback between wildfires, herbivore grazing, and rainfall variability impacts the amount of tree cover in the tropics Researchers found that fires stabilize savannas under intermediate rainfall values while increasing rainfall variability boosted the potential for sudden transition between forest and savanna A similar phenomenon was found under drier rainfall conditions, but in this case herbivores kept grasslands open Forest-savanna transitions have important implications for ecosystem services and people How tropical forests and savannas will function in the future depends on interactions between rainfall, fires and herbivores Staal A., et al..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

In this ZOOM video segment, cast member Francesco follows the paper trail to find out what happens to his recyclables. He visits a material recovery center and learns how paper is recycled and the number of trees that are saved as a result.

Follow along as this lecture doodle examines some of the basic reasons why trees are important not just for their beauty but also for their contributions to our health, our community of citizens, and our economic stability. Tree cover in our towns and cities contributes much. But because the benefits of trees are passive and accumulate slowly, they are unacknowledged until they are missing.
