In this video segment adapted from NOVA, scientists search for carbonized remains of plants preserved in lava flows to find out how long it has taken rain forests on Hawaii to regenerate after a volcanic eruption.

In this activity, students investigate the fascinating and complex process of decomposition and lay the foundation for deeper understanding of concepts related to matter and energy transfer in ecosystems. Through exploration and discussion, students go beyond simple definitions. Instead, students discover key characteristics of decomposition as they struggle with creating a sequence for decomposing wood and leaves. They learn the difference between physical decomposition and chemical decomposition and that many things contribute to decomposition, but certain organisms are classified as decomposers. They also search for and discuss evidence of decomposers, make model diagrams to further develop their ideas about the process of decomposition, and discuss decomposition and its role in the cycling of matter. Finally, students are challenged to recognize the evidence and impact of decomposition in the ecosystems they explore.

This video segment from NOVA: A Desert Place describes the physical characteristics and organisms that define the desert biome.

This video segment from Outdoor Nevada examines threats to the desert tortoise population.

In this lesson, students will embark on a journey of discovery by researching a specific biome of their choice, such as rainforests, deserts, or coral reefs. They will delve into the unique characteristics, flora, and fauna that define their chosen biome, gaining insights into its environmental challenges and adaptations. Using Tinkercad, students will then design and create a miniature 3D model representing their biome, incorporating elements like plants, animals, and geographical features. Through this hands-on activity, students will not only enhance their digital design skills but also deepen their understanding of ecosystems, biodiversity, and the delicate balance within different biomes. This lesson fosters creativity, scientific inquiry, and a holistic appreciation of the natural world in STEM education. 

In this Physical Geography Lab, students are responsible for designing a simple biological community.

This lab activity allows students to indetify macroinvertebrates and determine the health of an acquatic ecosystem.

This article provides links to web sites that describe the Arctic and Antarctica in terms of geography, climate, and ecosystems.

Mrs. Crowell takes her 2nd and 3rd graders on a nature walk where they use a dichotomous key to identify different species they encounter. This lesson shows a simple way to take students out on a walk and teach them how to identify species, no matter where they are.

In this project, you will explore a real-world problem, and then work through a series of steps to analyze that problem, research ways the problem could be solved, then propose a possible solution to that problem. Often, there are no specific right or wrong solutions, but sometimes one particular solution may be better than others. The key is making sure you fully understand the problem, have researched some possible solutions, and have proposed the solution that you can support with information / evidence.Begin by reading the problem statement in Step 1. Take the time to review all the information provided in the statement, including exploring the websites, videos and / or articles that are linked. Then work on steps 2 through 8 to complete this problem-based learning experience.

In this video segment from NatureScene, observe some methods of plant identification with regards to the diversity of hardwoods at the Congaree Swamp.

This video segment from the Science and Technology Chat series focuses on dolphin pregnancy, birth, and care of the young, and features Atlantic bottlenose dolphins living in captivity at the Mirage Resort Dolphin Habitat.

This resource has students role-play an Indigenous climate summit. It includes handouts about each Indigenous group and their concerns about climate change.

Students will learn field sampling and laboratory techniques to utilize environmental DNA (eDNA) as an early detection tool for invasive or rare species, with a focus on zebra mussels.

In this video, scientist Dr. Susan Prichard discusses the impact of pine bark beetles on western forests. She explains how climate change, specifically rising temperatures, is exacerbating the problem.

This video segment from Kentucky Life explains the differences between dragonflies and damselflies and explores their habitats.

In this jigsaw, students will graph various Bald Eagle population numbers and determine the impact humans have had on the eagle. Specifically, they will investigate why the Bald Eagle was listed as endangered, the affects of DDT on eagles, and the affects of lead. Based on an original activity titled "Bald Eagle Population Graphing" from The Raptor Center, University of Minnesota http://www.cvm.umn.edu/raptor/prod/groups/cvm/@pub/@cvm/documents/asset/cvm_66866.pdf

DATA: Pollen Viewer. TOOLS: Analyzing Digital Images, Spreadsheet. SUMMARY: Study the relationship between climate and the distribution of plants across North America, import data into spreadsheet and graph.

Rapid changes at Earth's surface, largely in response to human activity, have led to the realization that fundamental questions remain to be answered regarding the natural functioning of the Critical Zone, the thin veneer at Earth's surface where the atmosphere, lithosphere, hydrosphere and biosphere interact. EARTH 530 will introduce you to the basics necessary for understanding Earth surface processes in the Critical Zone through an integration of various scientific disciplines. Those who successfully complete EARTH 530 will be able to apply their knowledge of fundamental concepts of Earth surface processes to understanding outstanding fundamental questions in Critical Zone science and how their lives are intimately linked to Critical Zone health.

This lesson explores ecosystems and how living things are interconnected and is presented in Spanish
