You have seen on a blue sky, light, fleecy feather-clouds. They are very high up, and it is very cold where they are. You have also noticed the clouds at sunset with their beautiful colors. As the sun sank lower and lower, how did they change, in shape and color?
When clouds are low down, near the earth, we call them fogs or mist.
If clouds are cooled, the little particles of water gather into large drops and fall as rain. If the drops should freeze in falling, we would call them hail.
What shape are the raindrops? Of what use is the rain?

Sometimes, when it is very cold, the moisture in the air freezes before it forms into drops, and falls in the beautiful flakes we call snow. Have you ever seen snowflakes through a microscope?
Snow keeps the roots of plants warm. Many plants would die in winter if it were not for the snow. What other uses has snow?
Observe the clouds; fog, rain, snow, dew, frost, and tell what you have noticed.
Write what you have seen or noticed about vapor, clouds, rain, etc.
