Demonstration of the greenhouse effect and its role in climate change, discussion of the phases of water and the water cycle, and a hands-on experiment to investigate the role of temperature in phase changes of water.

Investigate water in a warmer world. This teaching box is filled with explorations and readings that help secondary students learn how climate change is affecting the water cycle.

In this lesson plan, students will trace the flow of water in the environment, investigate simulated effects of global temperature change on oceanic levels, evaluate changes within the water cycle, and explain several different...

The intricate relationship between precipitation and streamflow is illustrative of the complexity and changing nature of the water cycle. These key aspects can be investigated to help understand the water cycle. The duration and...

Using pictures from magazines, students will find sources of precipitation and water in this classroom activity. Students will then create a college of these pictures and group them based on the season.

Activities will help with understanding the concept of water condensation.

Students investigate water cycle processes by testing how cooling affects the rate of condensation of water vapor.

In this lesson plan, students use National Geographic FieldScope to investigate patterns of water availability and precipitation in the United States.

For this activity, students construct a terrarium in a bottle, and observe it over time to see when it 'rains,' which will indicate the completion of a water cycle.

An investigation that is part of a series of lab lessons that expose students to Earth Systems through research, data, and visualizations. In this lab, students will follow the pathway of water on a big scale and a small scale down to...

This site helps students construct a model of the arrangement of water molecules when present as solid, liquid or gas. Includes background information, lesson plans, links to standards and assessment ideas.

Water on the Web (WOW) is an advanced site allowing students to actively participate in data analysis from real research sites. Lesson plans on a range of topics are provided. There is also a tutorial for using Excel to graph WOW data.

Students will observe water evaporation in this performance task, and investigate the water cycle. The task is designed for Grade Two.

Investigate the changing states of water as you help Steve stay alive while in the Arctic. Includes background information about changing states of matter and about the water cycle, as well as a quiz.

The water cycle is investigated in this mini-unit, and water in its three states.

This learning module examines the Earth's stores of fresh water and how the balance between stores of water in the oceans and in ice is changing. Students then investigate how a maximum sustainable amount of freshwater can be achieved by...

Students investigate the water cycle in this mini-unit. Requires Adobe Reader. [PDF]

Eight hands-on lessons module in which students explore climate and weather. Inquiry-based investigations include observing weather, weather reporting, weather maps, weather satellites, causes of weather, and climate change.

Explore More is an online and broadcast series engages students in problems they can relate to, provides compelling content for investigation and gives students opportunities to form their own points of view on contemporary issues such...

Students investigate the effects of salinity on the formation of sea ice, and whether salt water freezes more quickly or more slowly than fresh water.

The U.S. Geological Survey offers information for teachers and students interested on Earth Science research. Contains references to general information as well as current research and events.

In this lesson, students will be able to explain and demonstrate the process of evaporation while discovering the variables that affect the rate of evaporation.

Students are introduced to the concept of air quality by investigating the composition, properties, atmospheric layers and everyday importance of air. They explore the sources and effects of visible and invisible air pollution. By...

An introduction to our solar system: the planets, our Sun and our Moon. Students begin by learning the history and engineering of space travel. They make simple rockets to acquire a basic understanding Newton's third law of motion. They...
