Water: H2O = Life
Water: H20=Life explores where water occurs on Earth, how it’s used, and how we can become better stewards of our water planet. This comprehensive guide will help you explore the exhibition with your students.
Use these free online resources before or after your visit to further explore themes presented in the Water: H20=Life exhibition.
Did you know that all living things need water? Or that the water on Earth today is all we will ever have? Learn more about this precious resource.
You know that oil and water don't mix, but what about saltwater and freshwater? Find out firsthand with this kid-friendly experiment that examines both salinity and density.
In 2000, building on its pioneering efforts in establishing Land and Sea Parks, the Commonwealth of The Bahamas initiated one of the world's first networks of marine reserves. This designation provided an international team of researchers with an unprecedented opportunity to study the physical, biological, and socio-economic impacts of such a network, and to integrate all of these aspects into recommendations for future conservation strategies. The project, which is focusing on the Bahamas as a model system, will hopefully be extended to other marine areas in the Caribbean and across the globe.
In the 1600's, New York City's Bronx River was a drinking water source and a sylvan haven for beaver, oysters, and herring. It became blighted as urbanization progressed, reincarnating as an industrial power source, an open sewer, and a garbage dump. Today, landscape ecologists are reconstructing the waterway's ecological history as a reference point for its restoration effort. Watch conservation teams coax new life into the Bronx River as they restock it with native fish, lay down oyster beds, and remove invasive species along its shores.
In a single century, the salmon population of Washington State's Elwha River shrunk by more than 99 percent. What caused this dramatic decline, and what can be done to turn it around?
Humans have harmlessly harvested coral reefs for thousands—or even hundreds of thousands—of years. So why has our behavior in recent years suddenly put reefs at risk?
Classroom Activity, Hands-on Activity
This "heavy" experiment allows students to discover that salt water sinks in fresh water.
If you've spent even a few hours in a pool, you know that the deep end is colder than the shallow. But do you know why? Experiment with colored ice cubes for insight into water density.
It's not surprising that the larger the world's population grows, the more fresh water we consume. But what is surprising is just how much of this precious commodity we've depleted in recent years.
If you've ever dipped your toes in the ocean, you know the water can be downright chilly. So how do whales and walruses manage to stay warm in frigid waters? Find out with this fun hands-on activity.
