Join the tree house detectives in learning about the processes of the water cycle, water conservation, water treatment, and water as a limited resource.

Young scientists explore Earth elements by conducting an experiment. They define water vocabulary terms such as condensation and precipitation. In addition, they conduct a water experiment in which they build a terrarium, so they can...

Students study the water cycle and how the sun is an important factor.  In this water cycle lesson students investigate how to desalinate water and explore the different densities of fresh versus saltwater.

Second graders observe images of prairie ecosystems and discuss the needs of living things. They create a prairie habitat in a closed jar to observe the water cycle and plant growth.

Students engage in a lesson which explores the wate cycle. They get to see some very entertaining video, do fun hands-on activities and gain a better understanding of evaporation, condensation, precipitation and collection.

Fourth graders study the water cycle and clouds. In this water cycle and cloud lesson, 4th graders determine the definition of condensation and watch a demonstration in which the teacher makes a cloud in a bottle. They discuss the water...

Here's a powerful demonstration that makes the point that it is everyone's responsibility to conserve water and protect the earth's limited supply of fresh water.

Students explore reasons for varied salinity in bodies of water. In this geographical inquiry lesson, students use a variety of visual and written information including maps, data tables, and graphs, to form a hypothesis as to why the...

First graders learn the basic needs of plants and identify geometric shapes while planting a fall garden. Combining math and science in one lesson, the resource guides kids through starting their class garden as they...

Students explore the properties of water. In this science lesson, students conduct various experiments to discover the importance of water. Math, language arts and history activities are also included.

Students discuss the role of water in transporting sediments and dissolved particles.  For this interdisciplinary lesson, students read about how water transports sediments and changes the landscape.  They complete a variety of...

Thirsty plants soak up every bit of a rainfall, but what happens to the rain that hits the roof? Calculate the amount of rainwater from your school's roof with an Earth science activity, which brings measurement skills, observation...

First graders go on a water walk, collect weather data, and measure rainfall for a month. They examine the water cycle in this series of lessons.

Students investigate the states that water may take. In this physical science lesson, students read the book, Water: Up, Down, and All Around and recall the states of water from the book. Students examine how water takes the shape of its...

Students investigate the lives of frogs by completing several worksheets.  For this biology lesson, students discover the life cycle of a frog from tadpole to death.  Students complete frog life cycle puzzle as well as create a...

Students create a compost cake. In this gardening and decomposition science lesson, students review and describe the "nutrient cycle." Students create a compost pile, measure and record the dimensions and temperature of the pile, and...

In this rain forest activity, students use different basic math skills to calculate the percentage of Earth covered by rain forests today compared to fifty years ago. They study the effects of how cutting down trees contributes to water...

Young scholars bag trees to determine the mass of the water given off in the evapotranspiration process.

Responsible farming is important for maintaining natural resources. Eager scientists complete a WebQuest to explore what happens to nitrogen when it enters the soil. They learn about the chemical makeup of nitrogen-based molecules...

After planting a bean seed in a jar, young scientists observe the growth patterns over several days. As the bean becomes a sprout, and the sprout becomes a plant, partners measure and plot the data. They notice patterns, practice...

Even rivers have tides. Older elementary schoolers will discuss the Hudson River and how weather, water craft, and the ocean cause tidal fluctuation. They will examine a series of line graphs that depict tidal fluctuation, then analyze...

  Learners observe a leaf and discuss the way that water is released from a leaf through its stomata.  For this water cycle lesson plan, students calculate how much water leaves produce from a whole tree.     

Students investigate the weather by reading children stories.  In this weather observation lesson, students read Cloudy With a Chance of Meatballs and several other stories about weather before they create a KWL chart....

What better way to learn about plant life than by creating a class garden? Young botanists start with a brief discussion about radishes before planting seeds and watching them grow. To determine the importance of water,...
