Teaching Cloud Identification

See the fish in the cloud?

We will be learning about the atmosphere and clouds and weather this year, so I wanted to share what I am using to teach Cloud Identification with you guys.  
This site has a free 2 page pdf file to print out with questions that help your student i.d. specific clouds.

And this site has many photographs and descriptions of each type of cloud.
