Common Clouds and what

• There are three types of
• humilis are wider than they are tall
• mediocris are as wide as they are tall

Can “grow” on
Form best under these conditions:
• Lots of warm and moist air
• Increasing winds make the cloud slant
• The atmosphere around the cloud needs to
Thunderstorms on the way!
• Stratus clouds are formed when large air
masses cool, also known as fog or mist.
• Stratus clouds are also the lowest forming
Light rain most likely
• Stratocumulus clouds are textured and puffy.
• Stratocumulus clouds usually form from
cumulus or stratus clouds.
Snow is possible
• Altocumulus clouds are very high in the sky,
so they are usually above the influence of
• The usual precipitation is light rain.
• Altostratus Clouds altitude is between 6,500
and 23,000 ft
• But since they are up so high they are the
reason for pretty sunsets.
• Usually thick and wet, with lots of
precipitation that is steady and slow.
• Formed from altostratus clouds when they
• Cirrus clouds are the highest of all clouds
and made of ice crystals.
• Cirrus clouds have no visible precipitation.
• Another cloud mostly made of ice crystals.
• Lots of large cirrocumulus clouds may
indicate bad weather.
• Formed in the troposphere in high winds.

My action plan is:
1. Teach students common cloud subject
2. Read cloud section in textbook.
3. Present Cloud PowerPoint.
4. Do worksheets, charts, and study guide.
5. Take quiz over clouds.
My goals are to teach the students the names of the clouds, the
appearance, the conditions they form in, and a few facts about the
Student was able to name 6 common clouds -6 points

Student was able to state the conditions needed for at least 2 of the
common clouds -3 points
Student was able to state at least one fact for 5 of the common
clouds -5 points
