March Nature Net News - Water Works!

"We forget that the water cycle and the life cycle are one."
-Jacques Cousteau

Dear Reader,

This issue of Nature Net News is dedicated to the wonders of the water cycle--one of nature's recycling factories. From collection to condensation, this cycle is part of the natural wonder of this world that keeps us going!

So sit back with a tall glass of water and get ready to learn about the timeless journey of this precious resource.

Did You Know...
There is no such thing as "new" water. All the water that ever existed on Earth still exists today and moves around the planet in an ongoing cycle. That means that the water you drink today could have been sipped by dinosaurs or dodo birds. It also means that the water around now is all we have, and it needs to be taken care of!

What to Do This Month
  • Watch icicles forming or melting.
  • Boil some water to see water vapor and then make tea with it.
  • Dance in the rain on a warm day.
  • Watch a rainstorm and then jump in its puddles. Try to find a rainbow!
  • Read the online stories of Drippy the Raindrop!
  • Sing some water cycle songs.

Tricks of the Trail for Parents
Water Works
It's perfectly fine (and fun!) to appreciate the water cycle first-hand, but do be careful if getting wet in chilly weather. Wear a raincoat, be prepared for winds, and always make sure to keep dry towels or socks on-hand for when you're done!

What Is the Water Cycle?

The Water Cycle is Mother Nature's original way of recycling one of her most precious resources!
The main stages are evaporation, condensation, precipitation, and collection.

Evaporation usually happens in nature when the sun heats up a body of water such as a lake, river, or puddle, turning the water into water vapor or steam. Steam also occurs at natural hot springs. Evaporation is also at play when humans sweat. The sweat meant to cool our bodies usually turns to water vapor after continued contact between hot skin and cooler air. Plants do not sweat, but instead transpire from their leaves, releasing water and water vapor back into the cycle.

After evaporation, water vapor floats upward in the atmosphere. The skies are the major setting for condensation, the next step in the process. Condensation happens when water vapor cools down and turns back into water. Instead of immediately falling in large drops, tiny water droplets gather into clouds. You can also see condensation on a hot day if you have a cold glass of water. The water vapor in the warm air will turn back into water when it touches the cold glass.

Once enough water has condensed in the sky, the clouds get too heavy to support themselves and begin to precipitate. Precipitation comes down to us in a number of forms, the most well-known including rain, hail, and snow.

Collection is when the precipitation falls back to earth and joins a body of water or soaks through the ground into groundwater reservoirs. Once the water is back in a lake, stream, ocean, puddle, or river, it is ready to restart the cycle by evaporating again.

Nature Craft
Water Cycle Bracelet

What you need: 12 inches of string or 1 pipecleaner, 1 bead of light blue, green, dark blue, yellow, clear, and white.

1. First string the dark blue bead. This bead represents water collecting in bodies of water.

2. Next add on the green bead on top of the dark blue bead. This bead represents the plants that use the water in the ground and then transpire it.

3. On top of the green bead, string the yellow bead. This bead represents the sun that provides the energy for water to become water vapor.

4. After the yellow bead, add the clear bead. This clear bead represents the air when the water vapor rises up, but has not become a cloud yet.

5. Next add on the white bead. This bead represents the clouds that form when the water vapor condenses.

6. Finally, add the light blue bead. This bead represents precipitation that falls back from the clouds.

7. After you've strung your beads, tie the bracelet in a circle to complete the cycle. Be sure it is a comfortable size around your wrist, and that you're able to take it off!

Cherokee Marsh, with 4,000 total acres, is by far the largest wetland in Dane County, created by former glacial Lake Mendota. Here you can walk in the midst of a cattail marsh. Or, follow the Yahara River boardwalk as it meanders through a sedge meadow, over peat deposits and past a fen - a distinctly different wetland from the cattail marsh. The park contains two observation platforms for wildlife viewing and several belly boards to encourage exploration of pond ecosystems. Other trails lead through prairie restorations, old field habitat, edge habitat, oak savannah, typical southern Wisconsin woods, over a glacial drumlin and to a glacial kettle pond.

Watch the water cycle in action! View the different ways and places water can be collected and see if you can observe any other stages of the cycle.
