Sea Level Trends - This lesson is designed as an introductory activity exploring one facet of global climate change — sea level change. Students will access real scientific data to investigate and compare long-term changes in sea level from different coastal locations around the United States.

Heat Capacity - Why does coffee take so long to cool down? Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? How can buoys help us explore these questions? In this hands-on introduction to heat capacity by the Bridge and COSEE NOW, students explore the concept and its effects on our daily lives. Students use ocean observing system data to investigate why water acts as a thermal buffer and the practical applications this has.

Winter Wonderland - From ocean water to snow, all of the earth's water is connected through the water cycle. Learn some of the water chemistry behind snow, then track this month's snowfall in your area and at the 2006 Winter Oympics.

Iced In - The winter of 2003-2004 was bone-chillingly cold for many regions of the United States especially the Great Lakes, a major shipping gateway. See how ice formation in the Great Lakes can influence wintertime shipping traffic.

Haunted by Hurricanes - The 2004 hurricane season was devasting, especially for Florida, bringing to mind many questions. Are hurricanes getting more intense? Lasting longer? More frequent? The answers may be blowing in the wind, but we'll look at hurricane data to try and elicit answers to these questions.

  Hold the Anchovies - In this data tip the Bridge collaborates with the Monterey Bay Aquarium Research Institute to examine the anchovy and sardine stocks in the Pacific. Has commercial overfishing brought these stocks to all-time lows, or might these be natural population fluctations tied to climate change?

Without An Ark - Coastal storms can bring extensive flooding resulting in highly publicized human suffering. But what happens to plants and animals in the wild when their habitat is flooded? Learn about some of the short-term impacts and potential long-term effects of floods on selected freshwater and estuarine organisms. Access real-time streamflow data from the U.S. Geological Survey and plot Hurricane Floyd floods.

The Return of El Niño - Another El Niño event has begun and with it will come a host of temporary climate changes. Follow some of these climate changes over the school year and see how this El Niño event compares to previous ones.

The Ozone "Hole" - Scientists recently discovered that the ozone hole above Antarctica has ceased increasing in size. This month we'll look at the NASA Earth Observatory's ozone data from the past 20 years to track changes in ozone levels and see if we're on the road to recovery.
