The Water Cycle!

Water Cycle

Yesterday, your students got to be water traveling through the earth’s water cycle! Using a simple game, students modeled how the water cycle works – we discovered that the real water cycle is more complicated that how its usually shown! Water can go through mini-cycles back and forth, traveling, for instance, from the atmosphere to the ocean and back to the atmosphere. Water can also become trapped for many years in the ocean, groundwater, or glaciers. This was a good model for the water cycle, but it doesn’t show everything. For instance, it does not show how much water is in every location.

Using another model (ask your students how it worked!), we demonstrated how almost all (more than 96%) of the earth’s water is stored in the oceans; the water we use for drinking and watering crops mostly comes from the tiny fraction that is stored as fresh water in rivers and lakes!

El ciclo del agua

Ayer, los estudiantes se convirtieron en “el agua” del “ciclo del agua” de la Tierra. Utilizando un simple juego, los estudiantes modelaron cómo funciona el ciclo del agua; y descubrimos que este ciclo es más complejo de cómo generalmente se enseña. El agua puede viajar de ida y de vuelta, en “mini ciclos, como, por ejemplo, cuando viaja de la atmósfera al océano y luego de vuelta a la atmósfera. El agua también puede quedarse “atrapada” por muchos años en el océano, en las aguas subterráneas o en los glaciares. El modelo del ciclo del agua que utilizamos es bueno, pero tiene algunas falencias, como que no nos muestra la cantidad de agua que hay en cada lugar.

Utilizando otro modelo (pregúntele a su hija o hijo como funciona), demostramos que la mayoría del agua del planeta (más del 96%) está almacenada en los océanos. El agua que tomamos o que usamos para regar los cultivos proviene, en su mayoría, de los lagos y ríos de agua dulce, la cual es una pequeña fracción del agua del planeta.

Dr. Catherine Sukow

Dr. Sukow's interest in science education began when she was a teenager, with an extended visit to San Francisco's Exploratorium. In college, she had summer jobs in a similar, smaller, museum. She focused her Master's research at NCSU on the structure of metal silicides on silicon, and her Ph. D. work at Brandeis on the structure of crossbridged actin bundles. While volunteering in her childrens' schools, she was reminded how much fun it is to teach science, and is happy to be teaching now with Science from Scientists. In her spare time, she also enjoys yoga, choral and solo singing, and attempting a variety of international cuisines.
