What type of clouds do
you see outside right
now? (you may use the
notes from yesterday)
• I can describe the different cloud types.
• I can record the weather accurately.
• I can show the different types of weather.
• Yesterday
– What did we do???????
• Yesterday
• Cloud types
• Today—types of weather
• Clouds are made of liquid water
– The water is in very small drops
– Some of these collide and combine to form
larger drops
– The cloud becomes thicker and grayer.
– Soon the drops are too heavy for the wind to
keep them in the air.
– They fall to the ground as precipitation.
raindrops
• When air temperature is warm; water
vapor forms liquid precipitation, or
raindrops.
Solid precipitation
• When the air temperature is below the
freezing point of water, water vapor forms
solid precipitation.
– Sleet
– Hail
– Snow
Sleet
• When raindrops fall through a layer of very
cold air near the ground, they freeze,
changing into tiny bits of ice called SLEET.
Hail
• Hail can form in severe thunderstorm
clouds when raindrops in the cloud collide
with bits of ice. The drops freeze, forming
hailstones.
• Wind will then push the hailstones back up
into the cloud and the hailstones grow
larger.
• Softball size
Snow
• Snow forms when air temperature is close
or below freezing.
• It is so cold it turns from water vapor to
solid crystal.
Measuring Precipitation
• Unit of depth (inches)
• Rain gauge: is a container that has a scale
marked on it in millimeters or inches.
• Refer to pages 382/383
• Recap today so far…………
• Tomorrow we will “make hail” in our
classroom.

liquid) (labeled)
