Students should have learned that the
weather we experience is due to many factors. It depends on how close we are
to land, water, and mountains. But it also depends on how the Earth rotates
through space. Movement of the atmosphere throughout the world helps explain
the weather patterns that we see. A combination of air in the atmosphere and
water from the oceans interact will influence our weather greatly.
Weather changes all the time. Weather is
created in the atmosphere that envelops the Earth. Weather changes so much
because the Earth is constantly spinning. Lands and water bodies heat up
differently that cause constant atmospheric change. Also note that
"seasons" are not the same as weather. Seasons have to do with the
angle of the solar radiation we receive caused by the tilt of the Earth on itís
axis. Seasons are explored in the Universe Cycle.
- Go over the different parts of the
Weather Placemat. The middle of the placemat is a Weather Map showing areas of
different weather. Review east, west, north, and south. Also review the
symbols that you will be asking them questions about (calm wind, clear day,
partly cloudy). Ask students to point out the following:
- Areas of snow. (northwest - north central, into
- area of calm wind (west)
- clear day (west, north west)
- partly cloudy (toward east coast)
- cloudy (north central)
NOTE: Do not question them about fronts, this is for a
- Name the four elements of weather. (Note that
elements refers to how we describe the weather in a basic way.)
- air pressure
- Ask students what instruments help us measure the
- anemometer - wind
- thermometer - temperature
- barometer - air pressure
- rain gauge - moisture from rain
- Where does most weather occur?
- Troposphere or 8-18 km above our head.
- The Earth spinning helps understand how what moves?
- How are clouds formed?
- when warm air meets cool air and moisture forms.
- Is the Water Cycle important to understand weather?
- Yes, the Water Cycle explains how moisture moves
throughout the Earth.
