SCS Objective

• Competency Goal 2 The learner will build an
  understanding of the changes in weather.
• --2.01 Describe weather by measurable quantities.

3
Essential Question

• WHAT ARE SOME OF THE CONDITIONS THAT AFFECT
  THE WEATHER?

4

• People have studied weather for many years. We
  have learned a lot about weather and we can
  sometimes predict, or guess, what kind of weather
  we will have. However, people can not control
  the weather and learning about it helps us
  protect ourselves.

5
Rain

• Rain is a type of precipitation that falls from
  the sky as liquid.
• Rain stays in the clouds until it becomes heavy
  enough to fall to Earth.

6
Sleet

• Sleet is small, partially melted pieces of
  ice.Sleet is formed when rain falls through a
  cold layer of air and freezes before falling to
  the ground.

7
Snow

• Snow is formed when water vapor freezes around a
  dust particle, making hexagonal crystals.

8
Hail

• Hail is small bits of ice that have a soft
  center.Hailstones can be big or small.

9
Thunderstorms

• Thunderstorms are common in our area.They are
  caused when warm air rises into the atmosphere,
  cools, and expands. This movement causes friction
  and electrical charges called lightning.

10
Tornados

• Tornados are narrow, funnel-shaped clouds that
  are made up of violent, twisting winds.Tornados
  do a lot of damage as they move along their path.

11
Hurricanes

• Hurricanes are giant storms that develop over the
  ocean. They have winds of 75 miles per hour or
  more.

12
Fog

• Fog is clouds that are very close to the
  earth.We often see fog early in the morning.

13
Dew

• Dew is water droplets on the ground caused when
  the air is full of moisture and it condenses onto
  cool surfaces, usually at night.We sometimes
  see dew droplets on grass and plants.

14
Clouds

• Clouds are tiny particles of water hanging high
  in the air.There are three main types of
  cloudscumulus, stratus, and cirrus.
