Letting Off Steam

Young scientists investigate the water cycle through a lettuce seed experiment. For this experiment, learners plant lettuce seeds inside of a ziplock bag in order to create a small greenhouse. They observe condensation and precipitation,...

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...

Dive into an exploration of the water cycle cycle with this simple earth science lesson. After first discussing where rain comes from, young scientists define the terms condensation, evaporation, transpiration,...

Observe the water cycle from the comfort of your classroom with this excellent earth science experiment. Working collaboratively, young scientists first create terrariums complete with hills, plants, lakes, and an...

Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...

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 plan and a PowerPoint...

Young scientists get their feet wet as they learn about the water cycle in this series of activities. Whether they are observing how evaporation causes puddles to dry up, or how plants put water into the atmosphere through...

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...

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. 

Access to fresh water is one of the largest drivers of creating a modern society, but what allows everyone access to seemingly endless supplies of potable water? It depends on where you live, but chances are that behind your tap there's...
