As the Atlantic Ocean warms, many marine speciesincluding commercially important fish stocksare moving further north along the Northeast United States. As a consequence, fishing boats based in traditional ports need to travel further to catch the same fish, or change their strategy to pursue different species of fish. In turn, businesses that serve fishing communities may need to purchase new equipment, develop new practices, or encourage workers to gain new skills. In order for fisheries and the businesses that depend on them to prepare for such changes, fisheries managers need tools to identify which fishery resources may be most vulnerable to our changing climate.

Students investigate different forms of hybrid engines as well as briefly conclude a look at the different forms of potential energy, which concludes the Research and Revise step of the legacy cycle. Students are introduced to basic circuit schematics and apply their understanding of the difference between series and parallel circuits to current research on hybrid cars.

If humans want to expand into space, it will take us incredible amounts of energy. How do we do that? Easy: we will just use the sun's energy by realizing the most ambitious construction project in history. This is how it works. The video "How to Build a Dyson Sphere - The Ultimate Megastructure" is a resource included in the Space sciences topic made available from the Kurzgesagt open educational resource series.

Students measure and analyze forces that act on vehicles pulling heavy objects while moving at a constant speed on a frictional surface. They study how the cars interact with their environments through forces, and discover which parameters in the design of the cars and environments could be altered to improve vehicles' pulling power. This LEGO® MINDSTORMS® based activity is geared towards, but not limited to, physics students.

If Neptune didn't catch Triton we might have another Dwarf Planet in our Solar system - maybe even another Planet or double system. We show how this could have happened. The video "How to catch a Dwarf Planet - Triton MM#3" is a resource included in the Space sciences topic made available from the Kurzgesagt open educational resource series.

Paul Andersen talks about the impacts of human growth on the environment and on themselves. The population, affluence, and destructive technology of a population impact the environment according to the IPAT equation. An analogous model is the ecological footprint which increases with development of a nation.

Paul Andersen explains how the world population has undergone exponential growth since the industrial revolution. Predicting the future world population is difficult because each country will grow at different rates. Age-structure diagrams and the demographic transition model can allow countries to plan for future growth.

Geography 430 is an active, creative learning community focused around understanding the changing relationships between people and their environments, the causes and consequences of environmental degradation, strategies for building a more sustainable world, and the methods and approaches that scholars have used to understand human-environment interactions. The primary course objectives are to help geographers, earth scientists, and other professionals to deepen their appreciation for the complexity of human-environment systems and to develop skills that allow them to interpret, analyze, and communicate effectively regarding human-environment interactions in their lives as students, professionals, and citizens.

Using thermometers, cotton balls, string and water, students make simple psychrometers—a tool that measures humidity. They learn the difference between relative humidity (the ratio of water vapor content to water vapor carrying capacity) and dew point (the temperature at which dew forms). Teams collect data using their homemade psychrometers and then calculate relative humidity inside and outside, comparing their results to an off-the-shelf psychrometer (if available). A lab worksheet is provided for data collection and calculation. As a real-world connection, students learn that humidity and air density is taken into consideration by engineers for many design projects. To conclude, they answer and discuss analysis and application questions.

Through four lessons and four hands-on associated activities, this unit provides a way to teach the overarching concept of energy as it relates to both kinetic and potential energy. Within these topics, students are exposed to gravitational potential, spring potential, the Carnot engine, temperature scales and simple magnets. During the module, students apply these scientific concepts to solve the following engineering challenge: "The rising price of gasoline has many effects on the US economy and the environment. You have been contracted by an engineering firm to help design a physical energy storage system for a new hybrid vehicle for Nissan. How would you go about solving this problem? What information would you consider to be important to know? You will create a small prototype of your design idea and make a sales pitch to Nissan at the end of the unit." This module is built around the Legacy Cycle, a format that incorporates findings from educational research on how people best learn. This module is written for a first-year algebra-based physics class, though it could easily be modified for conceptual physics.
