A Model Aquifer

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 water cycle is one of earth's most easily observable processes, but demonstrating each step within classroom walls can be a challenge. Through a series of videos and quick demonstrations, cover each aspect of the hydrologic cycle in...

How do scientists determine the best method for removing pollutants from our water sources? Environmental scholars experiment with pollution clean-up options to discover which are the most cost-effective, fastest, and most thorough....

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...

Model the transfer of energy during a typical 24-hour period. Young scholars use a game-like approach to learning the patterns of heat transfer through the day and night. Groups of four exchange different tokens as the energy...

Individuals explore solubility by modeling how water dissolves salts. They then view a video and compare how well water and alcohol dissolve salts, relating their comparisons to the structure of each molecule. 

Will tomorrow's soccer game be rained out? That depends on the water cycle. An animated feature explains precipitation, evaporation, transpiration, and condensation with diagrams and dialogue between Sam and RJ as they huddle under a...

Water pollution is everywhere, and pollutants range from oil to fertilizers. Bring the concept to life by demonstrating the difficulties in getting particular pollutants out of water.

Water filtration — that's pure genius! Groups test the ability of a water filter to purify water by running chlorine contaminated water through a filter and measuring the chlorine concentrations as they filter the water. They then graph...

Scholars discover the amount of the Earth's water in various locations such as the ocean, ice, the atmosphere, etc. They then make a model of the how much water those percentages represent. Finally, analysis questions bring the concepts...
