Contains information on REEF, an organization devoted to preserving marine life through education, research and involvement. It includes a fish gallery with images and information on a variety of tropical fish. Membership provides reduced-cost dive trips all over the world to conduct observational research while diving. New data is added daily from volunteers world-wide and is available for download ... Full description.

This USGS site contains graphs, tables, and charts for the following ground water topics: What is ground water, ground water flow diagrams, importance of groundwater, and trends in ground-water use. Ground water quality, pesticides, aquifers, waterwells, artesian wells, sinkholes, and land subsidence are also covered. There are a variety of links within all of the above topics and a very complete ... Full description.

For ecologists, the horseshoe crab is an important creature- a vastly adaptable organism that predates most species on the planet, with a lifecyle that is interlocked with other animals. Users can view information, photographs, and diagrams that explain the anatomy, range and habitat, lifecycle, ecological niche, reproductive cycle, and medical uses of the horseshoe crab.

Researchers such as paleoclimatologists or dendrochronologists use tree ring analyses as one tool to reconstruct climate information about the past. They will often reference data from other sources such as historical weather records, and ice core or ocean core samples to support their findings. In this lesson students will utilize monthly average precipitation data to strengthen conclusions about ... Full description.

In this lesson, students will play the role of a member of an International Team of Marine Biologists tasked with predicting and monitoring possible harmful algae blooms. They will evaluate changes in the ocean's chlorophyll counts from 1997-2007 using data sets from MyNASAData website, draw conclusions about how the chlorophyll-a levels in the ocean may effect its ecological characteristics and infer ... Full description.

In this lesson, students will investigate changes in air quality due to human interaction particularly burning of fossil fuels, and crop burning which increase levels of carbon monoxide. Students will evaluate changes in air quality over a 6 month time frame using Air Quality-Carbon Monoxide Data and draw conclusions based on observing color plot comparison graphs. Full description.

Phytoplankton, microscopic floating plant-like marine organisms (plankton means wanderer) are at the bottom of the marine food chain. They perform photosynthesis using water, carbon dioxide, and sunlight to produce glucose for their own use, as well as oxygen. Humans and all land animals and sea creatures are dependent on phytoplankton. The chlorophyll in phytoplankton can be observed by remote sensing ... Full description.

The Darby Creek watershed encompasses an area of approximately 550 square miles in central Ohio. The Big and Little Darby Creeks are well known for their vast diversity and abundance of aquatic and terrestrial plants and animals. They are home to eighty-six species of fish, five of which are endangered. Forty-one species of freshwater mollusks live in these waters, eight of which are on the Ohio endangered ...

Students will use NASA Satellite data to analyze and understand ways of studying photosynthesis from space. They will assume the role of a park ranger at Shenandoah National Park and determine when the plants and trees at their top efficiency by analyzing when the plants are absorbing a majority of the light hitting them (within the photosynthetic range.) Full description.

Using a color chart, students will make observations outside during each of the four seasons. During each session, they will try to find as many colors as possible and record what they see. As a class, they will make charts describing the colors they find in each season. At the end of the school year, students will compare their results and generate conclusions about variations in colors in nature ... Full description.
