In the science lab, students will create and observe the conditions necessary to make a cloud in a bottle.

Five chemistry lessons about phase changes between the states of mattter complete with handouts and animations.

In a class demonstration, students observe a simple water cycle model to better understand its role in pollutant transport. This activity shows one way in which pollution is affected by the water cycle; it simulates a point source of...

Students apply their understanding of the natural water cycle and the urban stormwater water cycle, as well as the processes involved in both cycles to hypothesize how the flow of water is affected by altering precipitation.

This lesson will introduce a phase change diagram, and show how a substance changes from one phase to another. It is 1 of 3 in the series titled "Phase Changes."

To understand a bubble chamber, picture the long, white streak an airplane leaves in its wake. That's water vapor produced by condensation from the plane's hot exhaust. Until the water particles evaporate, you can follow the streak to...

An indexing page for the HyperPhysics site. This page includes links to a variety of pages at the site which contain information related to phase changes. Each individual page consists of informative graphics and clear explanations.

A discussion from the Oklahoma Climatological Survey of the thermal factors effecting the movement of air masses in the atmosphere. Numerous topics such as methods of heat transfer, latent heat, phase changes (including sublimation and...

Water water everywhere. Check out this video clip and test understanding about the cycle of water from the earth to the atmosphere.

This site contains an interactive activity in which students can learn about the three states of matter. There is also a factsheet that lists numerous properties of liquids, solids, and gases. The factsheet also uses water as an example...

The operation of conventional air conditioners are described. Their parts and the refrigerant/heat exchange cycle is discussed. The use of alternative geothermal systems are explained.

This lesson will introduce a phase change diagram, and show how a substance changes from one phase to another. It is 3 of 3 in the series titled "Phase Changes."

This lesson will introduce a phase change diagram, and show how a substance changes from one phase to another. It is 2 of 3 in the series titled "Phase Changes."

This Homewood City Schools site has an outline form and contains lots of information about the classification and composition of matter. Some of the topics covered are matter and temperature, changes in state, composition of matter, and...

A page describing (in part) the distinction between energy, temperature and heat. Includes a graphic illustrating the quantity of energy needed to transform water between various states. Methods of thermal energy transfer (convection,...
