In this investigation, students will learn the basics of the Ecosytem-Based Management (EBM) approach to fisheries management and watch a short animation showing an example of one of the many types of EBM tools that can be used to aid fisheries management. Students will also play a game in which they make decisions about how to successfully manage different types of fisheries.

In the first part of the investigation, students will watch a short National Geographic slideshow presentation that will introduce you to some of the impacts that declining fish populations are having on humans around the world.

In this activity students will watch a short National Geographic slideshow presentation that will introduce students to some of the impacts that declining fish populations are having on humans around the world.

In this activity students will explore maps of changes in global marine biodiversity (the variety of life in ocean, sea, and coastal environments) over the last several decades.

In this activity students will interpret graphs comparing large predatory fish populations to total fish catch per year for the Atlantic, Pacific, and Indian Oceans.

In this unit students will learn about the role of soil respiration in transferring carbon from the soil to the atmosphere, the possible impact of a warming climate on permafrost, and how to identify any feedbacks between a thawing permafrost and the carbon cycle.

In activity Part A, students will learn about soil composition, decomposition and soil respiration. Students will also design and carry out a laboratory experiment on how soil respiration rates might be influenced by one of the following climate-related variables - temperature, soil moisture, soil nutrients, soil fertility, and soil type.

In activity Part B, students will use videos and readings to explore a very special soil with an interesting past and an uncertain future—the permafrost.

In this lab activity, students will learn about Marine Protected Areas, how they are classified, and how they can be powerful tools for protecting marine species and ecosystems. After completing this investigation, students should be able to: define the term Marine Protected Area; explain why MPAs are important for ecosystem and fisheries management; understand how MPAs are classified; identify a marine managed area near your home town; and identify factors contributing to the deterioration of the Gulf of California marine ecosystem.

In this activity students will check out real watersheds across the contiguous USA and explore the one in which you live.

In this activity, students will develop a working definition of drought and do a hands-on demonstration to understand the role of soil moisture in drought. Students will also examine precipitation data and streamflow levels and use them to predict where drought is most severe in the United States. Students will check their predictions by comparing them to the U.S. monitors drought severity layer.

In this lab, students will analyze data and interpret graphs and charts that show the distribution of the world's water. Students will develop a sense of where the world's water is, as well as where it's going.

Part A of this lab talks about where Earth's water is, but not about where it's going. Interactions between the sun's energy and Earth's gravity keep water moving through the water cycle at all times.

In this activity students will learn about the available water in the world. Students will look at projections of the amount of freshwater available in the future.
