Expanding on the topic of objects in motion covering Newton's laws of motion, acceleration and velocity, which are taught starting in third grade, students are introduced to new concepts of speed, density, level of service (LOS) (quality of roadways), delay and congestion. Every day we are affected by congestion even if we do not step out of our homes. For example, the price we pay for goods increases due to increases in shipping costs caused by congestion delays. A congestion metric would help us to compare roadways and assess improvement methods. A common metric used to measure congestion is called level of service (LOS).

Student teams find solutions to hypothetical challenge scenarios that require them to sustainably manage both resources and wastes. They begin by creating a card representing themselves and the resources (inputs) they need and wastes (outputs) they produce. Then they incorporate additional cards for food and energy components and associated necessary resources and waste products. They draw connections between outputs that provide inputs for other needs, and explore the problem of using linear solutions in resource-limited environments. Then students incorporate cards based on biorecycling technologies, such as algae photobioreactors and anaerobic digesters in order to make circular connections. Finally, the student teams present their complete biorecycling engineering solutions to their scenarios in poster format by connecting outputs to inputs, and showing the cycles of how wastes become resources.

Students learn that a healthy ecosystem is one in which multiple species are each able to meet their needs in a relatively stable web of life. Students learn that multiple species can have their needs met in the same ecosystem and that humans play a role in managing species within an ecosystem.

Students will apply the definition of stewardship in order to identify and understand the importance of considering both visible and invisible aspects of an ecosystem.

Students learn that when one part of a food web changes, it impacts other parts of the web. Students learn that stewardship decisions impact the different components of food webs in different ways.

Simulating the Tragedy of Commons illustrates for students to how sustaining our natural resources requires conservation and the cooperative use of those resources.

Students learn how farming has changed over time and how technology enhances the tools that farmers use enabling them to be even better stewards of the land.

Students learn that newly introduced species can affect the balance of an ecosystem and that the changes can be positive or negative. Students learn that humans introduce species for a variety of reasons including to solve problems.

In this video adapted from Texas Parks and Wildlife Department, learn about the prairie dog, the importance of its role in its ecosystem, and how it is affected by an ever-growing human population.

In this video adapted from Texas Parks and Wildlife Department, see how volunteers care for sick or injured animals. Also learn why human interaction is not always the best solution.

This video segment adapted from the NOW-RAMP 2002 Expedition documents a research expedition to Nihoa Island. It showcases Nihoa's unique birds and plants, the threat posed by invading grasshoppers, and restoration efforts.

In this video segment from Nature, see the value that sharks can have on the tourism industry in an area.

Students will understand that Wyoming is unique because we have space available for our livestock.

Students utilize their understanding of ecosystems, economic cost, and culture to make a stewardship decision.

Students discover how humans, insects, and animals play a part in the pollination of plants.

Short Description:
This open educational resource is designed for use by undergraduate and graduate ocean science, natural resource, fisheries and wildlife, and environmental policy students enrolled in a ten-week academic quarter. The purpose of this project is to provide students and non-law professionals with a freely accessible, clearly written guide to support engaging and effective learning. As such, the book serves as a gateway and an invitation to become a well informed, committed and involved ocean citizen as well as to explore the field beyond our course study. Data dashboard

The concentration of carbon dioxide in the atmosphere is the focus of this article; the units of measurement (ppm) are explained and the importance of monitoring that number as one of Earth's vital signs is also discussed. This article is part of the Climate Kids website, a NASA education resource featuring articles, videos, images and games focused on the science of climate change.

Engineers design methods of removing particulate matter from industrial sources to minimize negative effects of air pollution. In this activity, students will undertake a similar engineering challenge as they design and build a filter to remove pepper from an air stream without blocking more than 50% of the air.
