Small groups place sand and ice in a covered box, place the box in the sunlight, then observe as evaporation, condensation, and precipitation occur. These models serve as miniature water cycles and demonstrations of the three phases of...

Curious physical scientists follow a lesson on the properties of water with this lesson on distillation. They observe a miniature water cycle model that filters dirty water into clean water. These two lessons combined are an enriching...

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...

Students explain the function of the hydrologic cycle and demonstrate how transpiration rates can be experimentally changed.

Knowing about the hydrologic cycle is the first step to understanding the carbon cycle. Upper graders discuss the earth's water content, polar ice caps, and the concept of the ecological cycle as it applies to carbon, nitrogen, and other...

Present the water cycle to your middle schoolers with this lesson. After an anticipatory set, they participate in a Q & A session about the terms associated with the water cycle: evaporation, transpiration, condensation, and...

Students compare quantities of water. In this water lesson students examine the hydrologic cycle looking for the amount of fresh water that is available. Students use information from charts and diagrams.

Students create their own water cycle in a terrarium. In this water cycle lesson, students research the water cycle and complete a worksheet using the Internet. They create a water cycle of their own in a jar with stones, sand, soil, and...

Students examine the part that transpiration plays in the hydrologic cycle. They observe how plants play a role in maintaining a stable environment.

Eighth graders are introduced to the Earth's hydrologic system including the cycling of water in the atmosphere and the movement of water on the surface of the planet using the Great Lakes watershed as an example.

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...

Students explore energy and nutrient flow. In this science lesson, students diagram the flow of energy through food chains and food webs. Students discuss the importance of energy flow in Earth's ecosystems.

Students study the meaning of a water table and how it contributes to the existence of streams, swamps, and lakes in Nebraska. They conduct an experiment and complete a diagram of the hydrologic cycle.

Students explore potential issues of a water shortage.  In this water conservation instructional activity, students brainstorm the many uses of water and what life would be like if there was not enough water available.

Young scholars study drinking water. In this environment lesson, students draw the path of drinking water from the place of precipitation to the tap after researching a map and information from the United States Geological Survey water...

Students perform several water quality tests on groundwater from their area. They use test strips to determine the pH, hardness, alkalinity, nitrates, iron and chloride levels.
