In this lesson students will build on knowledge gained in the Hurricane Research lesson and the Hurricane Frequency and Intensity Lesson. Specifically, they will discuss the interaction (pathway) between a specific 'sphere' and the 'event' (hurricane). Working in groups, students will be assigned a specific sphere to look at more closely in relation to hurricanes. When all groups are finished, each ... Full description.

This collection of imagery and visualizations is derived from the geosynchronous and polar orbiting environmental weather satellites administered by the National Oceanic and Atmospheric Administration's (NOAA) National Environmental Satellite Data and Information Service. Other sources include the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT) and The National Space ... Full description.

This site provides information on several microscopic marine algae which are toxic to humans. Examples include Alexandrium, Dinophysis, Pseudo-nitzschia multiseries, and Domoic acid. Full description.

Contained on this page are satellite images pointed over different severe storm and special weather event areas. Each event has imagery that has been captured in the visible, infrared and water vapor frequencies. Locations vary depending upon current weather events. Full description.

This site contains an extensive list of frequently asked questions and short answers regarding the characteristics of icebergs. In addition, there are links to detailed descriptions of the six main types of icebergs, other interesting facts about icebergs, and photographs of Newfoundland icebergs. Full description.

This publication provides an overview of groundwater occurrence and of the main issues affecting its quantity and quality. It shows how the resource is used in our cities, in industry and mining, in agriculture and rural water supply; how it sustains many of our wetlands; how in its own undramatic way groundwater has become an integral part of billions of people's lives. Numerous examples illustrate ... Full description.

Research in Europe, Asia, Africa, and the Americas all point to the same conclusion: climate change is causing the world's glaciers to melt at an increasingly rapid pace. It is a phenomenon that may prove catastrophic for the millions of people in the world who depend on ice melt for their fresh water supply. This transcript of a broadcast story from Radio Free Europe/Radio Liberty summarizes the ... Full description.

In this activity, students play the roles of investigators looking for the source of fuel that is contaminating wells in a fictional town. They will use a topographic map and information about groundwater flow and well locations to determine the source of the pollution. Questions help students understand how groundwater flows and how a contamination plume spreads over time. In an extension to the ... Full description.

Students participating in this lab activity will construct a simulated aquifer in the classroom. The aquifer is constructed from readily available materials, and instructions, data sheets, vocabulary, and diagrams are provided. This simple model is intended for student inquiry into groundwater systems. Students are instructed to try things (within the context of the model), observe what happens, and ... Full description.

Materials presented here outline basic concepts related to groundwater, answering questions like "What is groundwater?" and "What is an aquifer?" More detailed topics include groundwater quality, sources of contamination, engineering problems presented by groundwater, and safeguards to the groundwater supply. A bibliography and links to other water-related sites are included. A French translation ... Full description.
