This site features GIFs, Java applets, MPEGs, and Flash animations that illustrate various forms of precipitation and moisture. They include an animation of air parcels and water vapor colliding with condensation nuclei which results in condensation and cloud formation, an interactive precipitation animation applet that allows the user to set wet and dry bulb temperatures to see if snow, ice, freezing rain, sleet, super cooled droplets, raindrops, or drizzle will fall, an animation of lake effect snow over the Great Lakes, and infrared satellite images of water vapor moving across the US. These resources portray a variety of environments and are suitable for use in lectures, labs, or other teaching activities.

This article provides links to hands-on science activities that could be used in an festival or informal learning event. National standards correlations are provided.

This project is for students in second grade who will be asked to further look at snow and how it affects their daily lives. Through this activity they will learn more about hazardous weather. Then they will make a conclusion as a group based on the information they found.

This article features activity books and polar-themed children's literature for use in the elementary classroom.

This article explains how the ice and snow of the polar regions fit in the global water cycle and includes links to professional development resources.

In this issue of the free online magazine, Beyond Penguins and Polar Bears, explore what the polar regions can teach us about the water cycle and the states and changes of matter. Find lesson plans about the many forms of water, ice, and snow found in the polar regions and how to use science notebooks to integrate literacy and science.

This article highlights children's literature about states of matter, phase changes, the water cycle, and glaciers and icebergs for use in the elementary classroom.

This article highlights children's literature about weather and climate, the polar regions, and climate change for use in the elementary classroom.

An excellent resource and a teaching guide to use with the book "Winter is Here" by Kevin Henkes. 

This encyclopedia entry is for the term "precipitation." Precipitation is any type of water that forms in the Earth's atmosphere and then drops onto the surface of the Earth. Water vapor, droplets of water suspended in the air, builds up in the Earth's atmosphere. Text for this entry is appropriate for the middle and high school grade levels.
