This teacher-directed demonstration provides a conceptual understanding of latent heat. Using the example of a chemical hand warmer, students learn about phase changes from liquid to solid and from solid to liquid and observe that one of these phase changes releases heat while the other requires heat to be added. These concepts are then reinforced in a demonstration which involves heating water and ... Full description.

Water quality is more than meets the eye. Some of its properties are invisible. Teachers using this module will focus on measurable properties of water: mass, volume, and concentration; temperature; dissolved oxygen; pH; and nitrates; and their effects on water quality. Each of these properties is the subject of a lesson plan. The lesson plans include an introduction, lesson objectives, a pre-test, ... Full description.

The purpose of this lesson is for students to explore the nature and composition of a comet. The student will select ingredients to create a comet and will learn to identify ingredients responsible for a comet nucleus, and how changes in the nucleus when the comet approaches the Sun cause two different kinds of tails to form. Students can explore some facts, myths, and legends linked to the appearance ... Full description.

This set of resources for younger students includes activities and information on thunderstorms, tornadoes, hurricanes, blizzards and clouds: how they form, and how they impact our lives. There are games about clouds, stories about extreme weather events, and a set of activities in which students create simulations of various weather phenomena such as fog, clouds, tornadoes, and others. The 'Recipe ... Full description.

This information is designed to belie the misconception that the capacity of air to hold water vapor is temperature dependent and that air can become saturated with water vapor. The temperature of a cloud droplet or ice crystal will be nearly the same as that of the air, so people imagine that somehow the air was to blame. But, if the other gases of the air were removed, leaving everything else the ... Full description.

This is a basic lesson on clouds. Very nice photos of cumulus and cumulonimbus clouds are presented on the page as well as a description of all major cloud types and their associated weather. Two activities are presented. One invites the learner to create a cloud, while the other involves creating a collage of cloud images along with information about the weather associated with each cloud type. Full description.

This information about the Lunar Prospector mission to the Moon discusses the possibility that ice exists on the lunar surface. The article indicates that no native water ice has been found on the moon. If ice has been found, it most likely originated from meteors and meteorites which periodically bombard the lunar surface.

The information on this site indicates that the life cycle of a glacier is more eventful than it appears. The site allows students to follow the journey of a single snowflake as it takes a ride through a glacier, a process that can take as much as 30,000 years to complete. It can be viewed as an interactive slide show or a single page of text and illustrations. Full description.

This site covers many of the components of cloud formation and cloud types. Although written for the high school level, the middle school student could grasp most of the concepts with the assistance from the teacher. Specific concepts covered include the importance of and mechanisms that produce rising air, cloud types, and ptyes of precipitation. There are nice graphics and images to support the ...
