For this science activity, students investigate the water cycle by testing the water evaporated from leaves (transpiration). They investigate concepts of evaporation and the movement of water through the different states of the water...

This study guide reviews the main ideas in the liquids chapter in this online textbook. Includes a chapter map, goals, a checklist, and answers to the chapter review.

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.

Create a water cycle story and storyboard.

This presentation, available in .pdf format, about liquids includes a chapter map, main ideas, and many pictures to help understand the chapter. Detailed charts go along well with the information.

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

Explains the different stages in the water cycle while covering important vocabulary. Supported by lots of visuals and includes a good water cycle animation.

This online textbook chapter discusses dynamic equilibrium between liquids and gases, boiling liquids, and particle attractions. Many pictures help to explain the concepts. Also find a detailed chapter review at the end to check for...

This 14-page document contains advanced information about Bose-Einstein condensation, providing historical background for the topic and explaining how BEC was demonstrated in 1995 by research laboratories. Requires ."pdf," software to...

Describes what relative humidity is, shows how it is calculated, and how it is related to evaporation and condensation.

Students learn about the techniques engineers have developed for changing ocean water into drinking water, including thermal and membrane desalination. They begin by reviewing the components of the natural water cycle. They see how...

Gives a brief introduction to Bose-Einstein Condensation (BEC) and how it was demonstrated at a laboratory at the NIST.

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

Learners will listen to a story about the water cycle, observe how water droplets form on a glass of icy water, then draw and label a picture showing condensation.

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,...

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will describe a liquid according to the kinetic-molecular theory. They will also learn how a liquid exhibits surface...

Students learn about the Earth's water cycle, especially about evaporation. Once a dam is constructed, its reservoir becomes a part of the region's natural hydrologic cycle by receiving precipitation, storing runoff water and evaporating...

Learn how states of matter can change as heat is added to a system.

Explains the three states of water, how the water cycle works, and the role of temperature. Includes a fun fact quiz.

Find out more about rainy days when you check out this resource, which features hands-on interactive activities, experiments, fun facts, and more.

[Free Registration/Login may be required to access all resource tools.] An introduction to the biogeochemical cycle, the water cycle. Recognize evaporation, sublimation, and condensation. Identify groundwater and runoff water supplies.

This animation discusses water and the water cycle in a storybook format. Condensation, evaporation, and precipitation are all covered.

Water is the source of life on earth. It exists in many forms and is constantly changing. The circulation and conservation of earth's water is called the hydrologic (or water) cycle. Find out how water evaporates, condensates,...

In this teacher directed inquiry indoor lab students collect snow in a cup. They will estimate how much water will be in the cup after the snow melts. Students will then make predictions about what will happen to the cup of water. After...
