The
Water Cycle explains interactions between the atmosphere, hydrosphere, and
lithosphere. Evaporation of water from the oceans, seas, rivers, and streams
into the atmosphere produce precipitation. Water can take the form of ice at the
polar caps and alpine glaciers. Water melts in spring, creating water runoff,
that either percolates through the Earth to become part of the water table or
back to the sea. Water Cycle looks at the elements of hydrogen and oxygen and
how it creates a compound (water) that is unique. The oceans are where most of
the water is found, but it is salt water. The movement of the oceans also has a
direct effect on the atmosphere. The atmosphere is that envelop of gas that
keeps organisms living on this planet. Oceans and atmosphere interact to give us
weather.
Students discover what properties of water make it the
perfect liquid for life. We learn about the molecular structure of water and the
uniqueness of water, including surface tension, capillary action, density, and
other physical properties. Students also learn about how the oceans, atmosphere
and weather are interrelated.
Water - Children learn that
chemical water is a unique compound. They experience the unique characteristics
that allow water to provide life on this planet.
Oceans - Students will see
that the Earth is a water planet, but most of the water is salty. They will
uncover the bottom topography as well as how oceans move.
Atmosphere - The envelop of
air becomes an exciting area that allows humans to move around freely.
Weather - Students will
begin to recognize the different elements of weather and how the oceans and
atmosphere provide the "fuel" for all weather phenomena.
