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: The Arctic and Antarctic Circles
In this student activity from Xpeditions, students research the ends of the Earth--the Poles--to compare and contrast the regions. Background information is provided, giving insight into the nature of these two areas and outlining their differences and similarities.
Standard(s): [SS2010] GHS (3) 1: Locate the prime meridian, equator, Tropic of Capricorn, Tropic of Cancer, International Date Line, and lines of latitude and longitude on maps and globes.
Title: Water Column Mix-Up
In this Xpeditions lesson, students investigate three broad ocean habitats--the intertidal zone, the pelagic zone (open ocean), and the abyss--and find out about some specific adaptations animals have made in each of these regions. They conduct Internet research and answer questions about what they find, and conclude by writing paragraphs describing what would happen if marine animals were placed in the wrong levels of the ocean.
Standard(s): [S1] AQU (9-12) 6: Describe adaptations that allow organisms to exist in specific aquatic environments.
