This Internet-based collaborative project will allow students to share information about water usage with other students from around the country and the world. Based on data collected by their household members and their classmates, students will determine the average amount of water used by one person in a day. They will compare this to the average amount of water used per person per day in other ... Full description.

In this laboratory exercise, students will design and conduct an experiment to evaluate the effect of the presence of biodegradable materials on dissolved oxygen levels. They will come to understand the effect of biodegradable pollutants on water quality, design and conduct an experiment, interpret data, suggest additional studies, and preform serial dilutions. The students will discover that in aquatic ... Full description.

This is a hands-on activity that fosters decision-making skills and emphasizes scientific principles such as objectivity and replication. It is designed to show that pollutants are not always obvious and not all contaminants pose a health risk. Students will learn that some contaminants can be detected by sight, smell, or taste and that others are not detectable except with sophisticated analytical ... Full description.

Discussion of holes in the stratospheric ozone layer usually revolves around investigations of the thickness of the layer near the South Pole. This online activity allows users to study the thickness of the ozone layer over any location on Earth to see how it has changed over time. This is done by plotting historical data from the Total Ozone Mapping Spectrometer (TOMS) Program, which has been in ... Full description.

This guide provides instructions for educators on how to use sea ice data in the classroom. The data, from the National Snow and Ice Data Center (NSIDC), describe sea ice concentration and extent of coverage. Scientists use it to monitor changes in the concentration and coverage of ice in polar regions and to compare changes over time, such as loss of extent. Topics include temporal trends in sea ...
