Ships travelling between Lake Ontario and Lake Erie use the Welland Canal. Beginning with a conversation between characters Mathise, Geo, and Trig, they explain how a lock in the canal operates by gravity alone, without pumps. The characters use mathematics to solve problems such as how long the locks take to fill and how to express the volume and flow of water in more common terms (bathtubs of water per second). They also ask why the lower lock door is much larger and heavier than the upper one, a question which users can answer by watching the animation of the lock's operation.
Using the European Space Agency's Infrared Space Observatory, Spanish and Italian astronomers have for the first time measured the total amount of water in cold regions of the Milky Way. The findings and implications of this research are discussed here, with emphasis on the fact that water is abundant in these cold regions and exists mostly in the form of ice. Images and videos are included.

This unit, designed to span two class periods, helps students understand that physical factors, particularly temperature and precipitation, limit the growth of plant ecosystems. The activity begins with a discussion in which students develop their own ideas about the role of temperature, precipitation, and environment on plant growth. They will then examine X-Y graphs of vegetation growth, temperature, and precipitation versus month for four diverse ecosystems to determine which climatic factor is limiting growth. A worksheet and scoring rubric are provided.
In this lesson, students will identify rivers in their local area and compile information about aquatic life in or near these habitats. Through research in various books or other sources, the students will learn more about the various animal and plant species living in riparian areas. The compiled information can be assembled into a class book, combining both text and drawings related to aquatic life.
Until very recently, planetary scientists had thought that Mars is a cold, dry planet. Then in the summer of 2000, NASA released images from the Mars Global Surveyor showing evidence of very recent seepage of ground water from crater and valley slopes in the planet's southern hemisphere. It seems that substantial reservoirs of the water that once may have run so copiously on the surface may still exist. Evidence of other water-created landforms is presented and accompanied by remote imagery.

Until recently, the total energy imparted to the oceans from the moon's gravitational pull has not been fully accounted for: about 30 percent had seemingly vanished without mathematical explanation. The total energy dissipating along the world's shallow areas and coasts don't add up to the expected total. However, data collected by the U.S./French satellite called TOPEX/Poseidon may provide the answer. Visualizations and remote imagery accompanied by text explain how the rough terrain of undersea mountains and ridges may dissipate the unaccounted-for energy.

This interactive map depicts real-time steam flow compared to historical stream flow for selected gauging stations in the United States and Puerto Rico. Users may select a state and choose a list of all stations in the state, a state map, or a list of the nearest stations. The map tracks short-term changes (over several hours) in rivers and streams. Its appearance may change very little from one hour to the next, but individual sites may change rapidly in response to major rain events or reservoir releases. Colored symbols represent real-time stream flow as percentiles of historical stream flow for the day of the year.
This site is based at Reading Memorial High School in Reading, MA. It features general information defining and describing vernal pools as a habitat type, including an illustrated cartoon series. Resources for educators and students include suggestions for classroom and field trip activities, examples of school projects, field guides, and teacher resources such as workshops. While this site contains several references to state-specific resources and regulations, it is relevant and useful outside of Massachusetts wherever vernal pools are found. The teacher responsible for the text on this site spent a sabbatical developing a resource kit for educators, which is available for purchase. Links are provided to scientific researchers conducting vernal pool studies, including their methods and results. There is an extensive page of resources, both digital in print. Educators and students are encouraged to download and use the collection of 78 slides of vernal pools and associated species on this site.
