Clouds
Cotton Ball Clouds
Make gray cloud shapes from construction paper. Have the children glue on cotton balls.
Watch the Clouds
On a partly cloudy day take the children out to watch the clouds. Talk about the shapes of the clouds. How do they move? What happens when they cover the sun? What colors of clouds are there? 

Paint with Clouds Supply each child with a piece of blue paper, a cotton ball and white paint. Have the child dip the cotton ball into the white paint and press onto the paper to make cloud prints.

Paint with a Cloud 2
Supply the children with a piece of white paper an many cotton balls and many different colors of paint, and have them paint with the cotton ball on the paper.
Playing with Clouds Put some shaving cream on the table. Tell the children to imagine that it is a cloud. To keep children to their own personal space use a paper plate for the shaving cream.
Blue Shaving Cream Art 
Add a few drops of blue paint to shaving cream. Have the children use this to paint with. Not mixing the paint in will give it a special look.
3-D Clouds
Cut out two identical cloud shapes from construction paper. Let the children paint these shapes with gray paint. For added texture, mix the paint with a bit of shaving cream. Allow to dry. Staple the shapes together, but leave about five inches un-stapled. Have the children stuff with newspaper then finish stapling around the edge. Staple a piece of yarn to hang the projects from the ceiling.
