Title: Alarming Frogs: The Life and Work of Emerging Explorer Tyrone Hayes
In this Xpeditions lesson, students learn about the ways National Geographic Emerging Explorer Tyrone Hayes uses a combination of laboratory and field study to learn about changes in frogs appearances as they relate to chemical contamination of water. Students choose to investigate one of three topics on which frog studies are helping to provide information--pesticide use, cancer, or cryopreservation.
Standard(s): [S1] MAR (9-12) 11: Describe positive and negative effects of human influence on marine environments.
Title: Weather and Agriculture
In this Xpeditions lesson, students research, discuss, and write reports on the relationship between climate and agriculture. They pretend that they've just purchased farms in specific parts of the United States and investigate that region's weather and climate in order to maximize the chances that their farms succeed.
Standard(s): [S1] GEL (9-12) 9: Describe the movement and storage of water in terms of watersheds, rainfall, surface runoff, aquifers, and surface water reservoirs.
Title: Biomagnification in the Great Lakes Ecosystems
This Xpeditions lesson focuses on biomagnification as it relates to the ecosystems of the Great Lakes region in the mid-western United States. As they work through the lesson, students diagram a food chain and label maps to show progress on environmental issues.
Standard(s): [SS2010] HGEO (9-12) 10: Recognize how human-environmental interaction affects culture in today's society.
Title: Models of the Water Cycle
The purpose of this Science NetLinks lesson is to develop an understanding of the cycling of water by building and evaluating two different physical models. In this lesson, students build and reflect on the usefulness of models that demonstrate the cycling of water in a closed system.
Standard(s): [S1] AQU (9-12) 3: Explain the importance of biogeochemical cycles in an aquatic environment.
