Soils, Water and Erosion

You've heard of farm to table ... but what about farm in classroom? Junior agriculturalists embark upon a two-week journey into the science of growing things. Based upon the classic terrarium in a two-liter experiment, the lesson goes...

Do you know how much water you have had in the last 24 hours? Do you know how much your body needs? In this hands-on activity, your class members will estimate how much water our bodies lose each day by filling and emptying one-liter...

Through a PowerPoint presentation and the embedded animation and video, earth science enthusiasts find out about the moisture in the soil beneath our feet. In the animation, follow a water molecule on its path through the water cycle. As...

Different substances can have different densities, but can the same substance have different densities? Lesson explores the effect of temperature on the density of water. Extension idea connects the concept of how melting ice in lakes...

Ecology candidates culture pond water organisms over a few days time, then they experiment to find out how increasing nutrients affects the population. As part of a unit on water, this exploration gives your class an understanding of how...

Using the polluted water that was made in the prior lesson, your young environmentalists will mix pollutants together in an experiment. Then, they will design a water filter that will clean the polluted water to use in the next lesson....

Explore all things water cycle in a truly engaging interactive. Water enthusiasts look at water as a system. They label the parts of the water cycle as they learn about them in a hands on activity, and then participate in a game where...

Be water wise! Science scholars learn the water cycle on a global scale in part seven of a 13-installment series. The hands-on interactive allows them to explore Earth's water storage, types of precipitation, and the cycling of water...

A hands-on activity helps learners explore the water cycle. After discussing how they use water, classes discuss water pollution and then move into a simulation where 20 pupils move through the water cycle based on description cards. 

Water that leaves the oceans must eventually return. The animations in the final lesson of the four-part NASA series show the complex path water can take across landforms before returning to the ocean. Approximately one-third of the...
