Coral Reefs in Hot Water is a short video displaying computerized data collected on the number of reefs impacted by coral bleaching around the world.

Active learning modules to help students understand the role of cover crop species selection and design of mixed species cover crop plantings on multiple ecosystem services. Our current goal is to integrate lessons-learned from 8 years of research and extension activities into undergraduate education modules that can be widely distributed. Students completing these modules would be able to describe why cover crops are used, how different species of cover crop affect an array of ecosystem functions, how mixtures can be used to increase the multifunctionality of cover cropping systems, and factors that control mixture growth across sites. If the modules are delivered in the following order then these concepts build sequentially.

In this lesson, students find their location on a map using Latitude and Longitudinal coordinates. They determine where they should go to be rescued and how best to get there.

In this activity students make biodiesel from waste vegetable oil and develop a presentation based on their lab experience. Parts of the activity include creation of bio-diesel from clean vegetable oil, creation of bio-diesel from waste vegetable oil, chemical analysis of biodiesel, purification of biodiesel, and creation of soap from glycerin.

Student teams design and then create small-size models of working filter systems to simulate multi-stage wastewater treatment plants. Drawing from assorted provided materials (gravel, pebbles, sand, activated charcoal, algae, coffee filters, cloth) and staying within a (hypothetical) budget, teams create filter systems within 2-liter plastic bottles to clean the teacher-made simulated wastewater (soap, oil, sand, fertilizer, coffee grounds, beads). They aim to remove the water contaminants while reclaiming the waste material as valuable resources. They design and build the filtering systems, redesigning for improvement, and then measuring and comparing results (across teams): reclaimed quantities, water quality tests, costs, experiences and best practices. They conduct common water quality tests (such as turbidity, pH, etc., as determined by the teacher) to check the water quality before and after treatment.

This activity is a field investigation of the biodiversity in a given area. The exercise will give students experience making scientific observations and creating a dichotomous key.

This activity is a field investigation where student gather data on organisms they find in or around a pond.

This activity will help students learn about Minnesota animals and characteristics that distinguish them from one another.

Students choose one of four short articles to read about mineral mining, including the impacts of mining on the Native American community in the region. Each article highlights a specific example where the Indigenous community's interests are in conflict with the mining company's interests. After reading one of the articles, students post a short reflection to a discussion board, then respond to at least one classmate's reflection.

This visualization tool shows sea ice data from 1978 to the present. Selected data can be animated to show changes in sea ice extent over time. Data is added by the National Snow and Ice Data Center as it becomes available.

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.

This online gallery of photos, illustrations, and videos provides a snapshot of deep sea vents and the ancient forms of life that can be found within them. Transcripts of the videos are provided, and the photos and illustrations are accompanied by explanatory texts.

This NASA animation on land cover change zooms into Rondonia, Brazil. It starts with a Landsat satellite image taken in 1975 and dissolves into a second image of the same region taken in 2009 that illustrates a significant amount of land use change.

In this video segment adapted from Navajo Technical College, meet a dendroclimatologist who studies the relationship between precipitation and tree growth in the Navajo Nation.

In this lab activity, students determine density differences of water samples with varying temperature and salinity levels. Students synthesize information to predict the effects of oil in given water samples.

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.

Students are challenged to design a permanent guest village within the Saguaro National Park in Arizona. The design must provide a true desert experience to visitors while emphasizing sustainable design, protection of the natural environment, and energy and resource conservation. To successfully address and respond to this challenge, students must acquire an understanding of desert ecology, environmental limiting factors, species adaptations and resource utilization. Following theintroduction, students generate ideas and consider the knowledge required to complete the challenge. The lectures and activities that follow serve to develop this level of comprehension. To introduce the concepts of healthy ecosystems, biomimetics and the importance of sustainable environmental design, students watch three video clips of experts. These clips provide direction for student research and challenge design solutions.

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

This activity is a field investigation where students gather population data on bird species. The students will create bar graphs and interpret their findings. Based on their experiences and data, they will write an answer to the guiding question.
