Gather and display local weather information such as temperature, precipitation, clouds, etc. (DOK 3)
Instruments (wind vane, rain gauge, thermometers, anemometers, and barometers)
Cloud types (cirrus, stratus, cumulus)
Water cycle (evaporation, precipitation, condensation)
I I. Evaporation
Evaporation
is when the sun heats up water in rivers or lakes or the ocean and turns it
into vapor or steam. The water vapor or steam leaves the body of waters and
goes into the air.
A. Bodies
of Water
1. Oceans
2. Rivers
3. Lakes
B. Ground
Water
Condensation
is the process where water vapor in the air is ... changed into liquid water.
Condensation is crucial to the water ... cycle because it is responsible for the
formation of clouds.
A. Water
Vapor
1. Dew
The
water droplets formed by condensation of water .............. vapor on an object with a
relatively cold surface.
2. Clouds
B. Water
III. Precipitation
When
there is so much water that it condensed in the air and ... cannot hold it anymore.
The clouds get heavy and water falls .... back to the earth in different forms.
A. Snow
2. Hail
B. Rain
IV. Collection
When
water falls back to earth as precipitation, it may fall back ......in the oceans,
lakes or rivers or it may end up on land and soak ......into the soil.
A. Bodies
of Water
B. Ground
Water
2. Wells
V. Transpiration
Transpiration
is evaporation of water from plant
leaves.
Moisture
is carried through plants from the roots to the ....underside of leaves, where it
changes to a vapor and is released .....into the atmosphere.
A. Leaves
1. Flowers
2. Trees
B. Roots
Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapor or steam. The water vapor or steam leaves the body of waters and goes into the air.
