The Water Cycle

The Water Cycle
[in Spanish] © Contributed by Leanne Guenther Run and get a glass of water and put it on the table next to you. Take a good long look at the water. Now -- can you guess how old it is? The water in your glass may have fallen from the sky as rain just last week, but the water itself has been around pretty much as long as the earth has! When the first fish crawled out of the ocean onto the land, your glass of water was part of that ocean. And you thought your parents were OLD The earth has a limited amount of water. This cycle is made up of a few main parts: evaporation (and transpiration) condensation precipitation collection Evaporation: Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapor or steam. Do plants sweat? Well, sort of.... Condensation: Water vapor in the air gets cold and changes back into liquid, forming clouds. You can see the same sort of thing at home...

Warnings from the Ice Antarctic Almanac Ice Antarctica has some seven million cubic miles of ice, representing some 90 percent of the world's total. The ice averages one and a half miles in thickness, with the thickest ice being almost three miles thick. Antarctica's ice is so heavy that it compresses the land surface over much of the continent to below sea level. QCA document Visit the Canterbury Environmental Education Centre ( details ) and undertake one of the relevant programmes, 'Water Cycle at Broad Oak Lakes' 'Weather Days' or the 'Great Stour River Study.' The Great Stour River Study programme involves walking along a section of the river refering to maps, noting relevant geographical, man made and biological features and undertaking simple experiments (for example measure differing speed of channel flow). Visit the Virtual Tour pages to take this walk along the Great Stour, which can be used to prime or reinforce the field work. The Photo and Map pages are a good source of secondary information. The photographs focus on the Great Stour River along its course and the maps show the catchment area, topography and geology of the Gt Stour River basin.

Trout Unlimited, Connecticut Council of Trout Unlimited Trout in the Classroom Teacher form ABOUT TICTrout in the Classroom (TIC) is an innovative education program desigend to bring students' studies of the natural world to life. Each year, classrooms across the state are equipped with specially designed trout rearing tanks. Teachers, aided by a Trout Unlimited coordinator, work with their students to raise trout from eyed eggs to fry, releasing their trout into an area river towards the end of the school year. During the course of the year, students learn about the importance of healthy river ecosystems and how claen, cool water is a critical need of trout and other aquatic life.

Earth Floor: Cycles The Water Cycle Water on Earth is always changing. Its repeating changes make a cycle. As water goes through its cycle, it can be a solid (ice), a liquid (water), or a gas (water vapor). Ice can change to become water or water vapor.

Between two-thirds and three-fourths of its surface is water. Oceans supply the most water, but it also can be found in ponds, rivers, in clouds, and in lakes. The Earth is full of water. Origin of Life Originally, the tree of life was viewed as a classification of life, reflecting underlying deep patterns of nature. After Darwin, that pattern has been generally thought to be an evolutionary one. This then leads to the question of the root of the tree; i.e. the origin of life. On this, Darwin was reluctant to publicly speculate. Indeed, the Origin of Species cuts off at this point with reference to creation of one or a few initial simple life forms that then evolved through descent with modification into the pattern we see today and in the fossil record. But, in a private letter to Joseph Hooker in 1872, he suggested:

Space - Digital Education Resources All Time-lapse sequences were taken by the astronauts onboard the International Space Station (ISS) (Thanks guys for making this available to the public for use!) All footage has been color graded, denoised, deflickered, slowed down and stabilized by myself. Clips were then complied and converted to 1080 HD at 24 frames/sec.
