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.
