Curated OER
Evaporation of Alcohol and Water
Students investigate the process that occurs when liquids evaporaate. They test water and alcohol to determine which substance evaporates more quickly and relate the rate to energy changes.
Curated OER
Evaporation and Condensation
Learners explore how temperature effects the processes of evaporation and condensation and how the air may be polluted by the evaporation of certain compounds. In this temperature lesson students complete a lab and a worksheet.

Physical Changes and the Water Cycle- Three
Third graders take note of the changes in the water level in a cup of water that is left out. Using a model of the water that depicts a lake and landscape that is being heated by a heat lamp, the students observe precipitation, and...

How Can Clouds Keep the Air Warmer?
Condensing water warms the air around it. Young scholars consider this concept as they experiment with air temperature around evaporating and condensing water vapor. They simulate the formation of clouds to experience the associated...

Water Cycle Activities
Explore the water cycle in all aspects with a resource packed full of activities and lessons. The 37-page packet comes with vocabulary, a game, writing prompts, printables, and opportunities to journey through the stages in the water...
Curated OER
The Water Cycle
Your class sets up a mini water cycle model to examine the process. Then they watch an animation, following a water molecule through the cycle. A well-developed lab sheet guides learners through the lesson and a PowerPoint presentation...

The Hydrologic Cycle
There is the same amount of water on earth now as there was when it was formed. The water from your faucet could contain molecules that dinosaurs drank! Young scientists build their own hydrologic cycle model and observe...
National Energy Education Development Project
Exploring Hydropower
In 2006, about 20 percent of the world's electricity was generated from hydroelectric power. In the presentation, scholars review the water cycle and gravitational energy to begin to understand how humans harness the power of water. They...
Curated OER
Water Conservation
Open learners' eyes to the challenge of finding safe drinking water – something we often take for granted in our country. The PowerPoint presentation includes images, graphs, diagrams, and even a video to stimulate discussion on how we...

Weathering of Limestone
We all know limestone weathers, but what affects the rate of weathering? Young scientists investigate the physical and chemical weathering of limestone (chalk) through experimentation. First, they conduct trials with different-size...
Curated OER
The Science of Weather: Humidity makes air feel even hotter.
Young scholars examine the effects of heat and humidity. In this weather instructional activity, students read a chart to determine the effects heat and humidity can have on the human body. This instructional activity includes an...
Curated OER
Rock Candy
Fourth graders observe and demonstrate the physical change of dissolving sugar in water and evaporating the water to examine the physical change that has occurred. They discuss physical changes and solutions, and make rock candy,...
Curated OER
Moist Air & Clouds
Fifth graders study the weather and water cycle of clouds. In this water cycle instructional activity, 5th graders read background information about evaporation, condensation, and the states of water.
Curated OER
Ecology
Students identify and describe three states of water. They predict how water will change states.
Curated OER
Natural Refrigeration
Students build a refrigerator that does not require electricity. In this environmental science lesson plan, student consider desert dwellers of Africa who have no access to electricity. Students use flower pots, sand and water to study...

What is Drought? No Rain, No Water
How can climate change affect our water supply? Have kids read a passage about the water cycle and water conservation, which includes six questions that challenge them to use context clues.
Curated OER
Boy, Is That Buoyant!
Fourth graders see that salt increases the density of water and creates a condition wherein objects are more buoyant than would be expected under normal conditions. They describe the relationship between heat energy, evaporation and...
Curated OER
Rain Machine (Solar Still)
Students experiment with a solar still. In this distillation lesson, students find a simple way to use evaporation to make salty water drinkable.
Curated OER
Watercycle
Third graders examine the natural circulation of water from oceans, lakes, and rivers to evaporation into the air, and then to condensation to produce rain falling back to the soil as components of the water cycle.
Curated OER
The Effect of Rain on Morning Temperatures
Eighth graders study the effects of the water cycle. They create a graph of the air temperature versus solar radiation on a rainy and clear 24 hour period using data from a provided link. Afterward, they answer questions to determine the...
Curated OER
Survival Still
Learners explain how to desalinate water using solar energy. In this solar lesson students complete a lab activity and explain capillary water.
Curated OER
Water Into Gas
Learners investigate how temperature and pressure cause a material to change phase. They heat water to reclaim a gas. They demonstrate that different liquids evaporate at different temperatures.
Curated OER
Water Cycle
Students perform experiments with water to observe the principles of evaporation and condensation. They make models of the water cycle and discuss the processes that occurred in their experiments with their jars of water.
