Mr. Fetch’s Earth Science Classroom
Teaching Topics
GROUP 1
What is weather
Temperature
GROUP 2
Wind
Barometric Pressure
GROUP 3
Moisture in the Atmosphere
GROUP 4
Prepare a short lesson
on your section of the
material to present to
the class.
Describe in detail the
information in your
notes.
You will be “teaching”
the class this material.
Not me!!
You must be able to
explain the pictures in
your notes. I will have
them on the board.
Use them as you teach
the class.
Moisture or Humidity (don’t to Relative Humidity)
Mr. Fetch’s Earth Science Classroom
What causes weather?
The sun warms
earth’s surface
increasing its
temperature.
The sun’s
energy is used
to evaporate
water and put
moisture into
the air.
Air rises
and cools
to form
clouds
• The transfer of energy between:
- The sun
- Earth’s surface
- The Atmosphere.
Water vapor condenses to from
precipitation and releases energy into
the atmosphere
Unequal heating and differences in air pressure cause wind.Mr. Fetch’s Earth Science Classroom

Factors that affect temperature
Cities are Warmer Mountains are Colder
Cloudy days Cloudy nights
are Cooler are Warmer
