Types of High-level Clouds

  • There are three types of high-level clouds:

  • Usually mean good weather.

  • What does a cirrus cloud look like?


  • Thin and sheet like.

  • Brings bad weather.


  • Rows of long white puffs.

  • Look like fish scales.

  • In tropical regions.

Types of medium level clouds
Types of medium-level Clouds

  • There are two types of medium-level clouds:

    • Altostratus

    • Altocumulus

  • Medium-level clouds are between 6,500 – 18,000 feet in the air.


  • Are colored gray or blue-gray.

    • Nimbostratus

  • Low-level clouds only go up to 6,500 feet in the air.

Stratus clouds
Stratus Clouds

  • Stratus clouds cover the whole sky.

  • Looks like fog in the sky.

  • Brings light rain.

  • Weather Wiz Kids


  • The assignment is this worksheet:

    • Clouds and What They Mean

Objective:The objective is to teach my students the general knowledge of clouds. That includes the different types and what each one does.


I will have the students do a worksheet that will test them on the different types of clouds.

I will also create a test or quiz that will test them on the content of the power point. Also, if they can determine the differences between each of the different clouds.
