This science assignment produced by NASA teaches inquiring minds the distribution of Earth's water. Learners will appreciate and understand the importance of fresh water and how weather and climate affects everything.

Equip young campers with important survival knowledge with a set of engaging lessons. Teammates work together to complete three outdoor activities, which include building a shelter, starting a campfire, and finding directions in the...

Groups use alcohol and chromatography paper to separate the color components of black ink. The purpose of the activity is to allow the class to become aware that mixtures exist in hidden places. 

The liquids did not mix — so what do density columns have to do with it? The seventh part in a series of nine provides the theoretical explanation of why density columns do not mix. The lesson covers the topics related to...

How do cohesion and adhesion work together? The third installment of a nine-part series teaches young scientists the difference between adhesion and cohesion. They also learn how cohesion and adhesion work together to cause capillary...

Explore capillary action from different perspectives. In the fourth installment of a nine-part series, scholars perform several experiments to observe capillary action. They look at the meniscus of water in a glass, observe capillary...

Examine how pollution makes its way into an ocean with help from a model watershed. Scholars use household items to recreate a mini-watershed, equipped with pollutants, that when mixed with rain drain into a model's body of...

What's in your water? And, why is water quality so important? Enhance your class's level of water appreciation through a lesson that demonstrates the necessity of water quality. Environmental enthusiasts explore the EPA's Clean Water...

Controlling the efficiency of a greenhouse is a mathematical task. A collaborative project challenges learners to create an efficiency plan for a closed greenhouse. Using algebraic equations, they consider a set of constraints, design...

How do people transport fresh water long distances to ensure everyone has access to it? The final lesson in the 10-part Fresh Solutions unit encourages individuals to design their own solution, or solutions, to that very problem. Groups...

Switching indoor water fixtures to low flow reduces water usage by more than 45 percent. This and other solutions to reduce water usage have both pros and cons. Scholars view videos of different solutions, discuss them in small groups,...

Nitrogen is an essential element for productive farming. An interactive lesson explores the chemical makeup of different fertilizers and their corresponding nitrogen content. The interactive challenges individuals to complete...

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

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.

Students create acid rain using carbonic, nitrous, nitric, and sulfurous acids.

Students study how water infiltration can carry pollution underground. In this water infiltration lesson, students conduct an experiment on water infiltration and underground pollution.

Students examine the components of the water cycle and follow step by step directions to build a three dimensional cloud. The vocabulary words used in the lesson are attached to the cloud for a lesson review.

Ninth graders study how cities affect the environment and design an ecologically-sound city. They focus their study on the benefits and constraints of life on the Northern Great Plains.

Learners participate in a demonstration showing the concept of precipitation. They view the hydrologic cycle and identify its stages, and discuss flash flood safety at the end the lesson.

Students engage in a lesson that investigates the hydrological cycle. They create bracelets with different colored beads that represent parts of the cycle. Students can follow the cycle in the order of the beads. The lesson includes...

Young scholars read about and discuss water and how it is used as a resource and how engineers use technology to preserve it. In this water lesson plan, students look at a picture of water treatment and tell what is wrong with the picture.

Students find ways to decrease soil runoff for an African Village as a part of a Peace Corps project. In this soil runoff lesson, students play a soil runoff challenge online. Students complete online activities and view a slide show to...

Students examine water issues in Africa. In this global issues lesson, students complete a webquest that requires them gather information. Students use the information to prepare for a World Water Summit simulation.

Students study drinking water. For 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...
