Science LessonGOAL: TO UNDERSTAND TERMS RELATED TO THE WATER CYCLE!
Water Cycle
Definition: the continuous movement of water on, above, and below the surface of the Earth.
Example: Every time it rains!!!!
Bedrock
Definition: The hard solid rock under the surface of the Earth.
Example: a large area in the ground that is covered in rock
Sediments
Definition: Sediments are made up of small loose rocks and parts of clay made by the weathering of rocks and soil (rain and snow hitting rocks).
Example: small rocks below large rocks
Consolidated Rock
Definition: solid and tightly bound rock
Example: A large boulder!!
Unconsolidated Rock
Definition: When the weather breaks large rock into smaller ones.
Example: rocks at the bottom of a hill
Particles
Definition: a small part of something that is bigger
Example: dirt
Zone of Saturation
Definition: - The ground below the water table that is totally soaked.
Example: in the middle of a lake or stream
Aquifer
Definition: a deposit of rock such as sandstone, containing water that can be used to supply wells.
Example: a well located at a house in CT
Water Table
Definition: The top of the water surface in the saturated part of an aquifer. Line between wet and dry soil
Example: the surface of a lake
Percolation
Definition: the draining of water through a permeable surface
Example: water soaking through small rocks and then turning into runoff
Permeable
Definition: Allowing liquids or gasses to pass through.
Example: water flowing through a rock with small holes
Cold Air
Definition: helps form tiny water droplets when water vapor cools (condensation)
Example: helps condensation take place in a cloud
Condensation
Definition: Water vapor cools and turns from a gas into a liquid.
Example: water drops forming on a glass jar that has water in the bottom and a top on the top edge of the jar.
Evaporation
Definition: Water changes from a liquid to a gas (caused by heat)
Example: the water in the ocean continues to flow because it literally continues to recycle its own water!!
Runoff
Definition: precipitation that did not get (infiltrated) absorbed into the soil, or did not evaporate, and therefore made its way from the ground surface into places that water collect.
Example: water flowing down a mountain and into a lake (see picture)
Definition: Vapor is water in a gas form.
Example: Vapor rises from a lake after it has been heated by the sun.
Water Vapor
Definition: The process of a solid changing to a gas without ever changing into a liquid.
Example: Dry ice is solid carbon dioxide and instead of melting into a liquid releases gas into the air.
Sublimation
Definition: Water droplets collect around dust to form clouds.
Example: Small particles in the air (dust) help create clouds as water vapor attaches to the dust and condensation (liquid water) occurs.
Dust
Definition: The sun provides the energy for the water cycle.
Example: The sun gives water heat so evaporation can occur.
Sun
Definition: Heat from the sun causes evaporation.
Example: Water vapor rises after it has been heated.
Heat
Transpiration
Definition: water given off from trees
Example: water given off from an Oak Tree
Precipitation
Definition: rain, snow, sleet, or hail
Example: when it rains
Collection Point
Definition: Water locations that collect water runoff such as lakes, rivers, streams, and oceans.
Example: Water collecting in a pond
Ground Water
Defintion: Water located under the Earth’s surface.
Example: Water at the bottom of the ocean.
Vegetation
Definition: plants and trees in a given location
Example: Palm Trees on the beach in Key West, Florida
Absorption
Definition: water absorbed by plant roots
Example: water soaking into plant roots
absorption
Consumption
Definition: animals or plants drinking water
Example: zebras drinking water
Perspiration
Definition: a salty, watery fluid secreted by the sweat glands of the skin, especially when very warm as a result of strenuous exertion; sweat
Example: a young lady sweats (water on their skin) after playing a basketball game
Excretion
Definition: The act or process of discharging (getting rid of) waste from the blood, tissues, or organs.
Example: urine or sweat is excreted from the body
