Overview:
Many forms of precipitation exist. In this activity, students will learn about the mechanisms that produce the various types of precipitation. Specific conditions must exist in order for precipitation to occur; the presence of clouds does not guarantee precipitation. The conditions also determine which type of precipitation that may fall. By doing this exercise students will understand how conditions can influence precipitation.

Objectives:
1. Students will learn how to use the climatology section of the Digital Atlas of Idaho.
2. Students will be able to describe the characteristics of different types of precipitation.
3. Students will be able to predict what types of precipitation should exist under different conditions.

Procedure:
Students will use the Digital Atlas of Idaho. To get there: Click on Atlas Home, Climatology, then on Precipitation Patterns. Encourage your students to explore the Precipitation Pattern page and click on the various links to view the pictures. Use this information to answer the following questions. Click below for a printable pdf handout that you can give your students for this activity.
