Intended as a follow up to the Protecting Your Drinking Water activity, young environmentalists use their assessment of the a hypothetical town's water supply to debate the installation of underground chemical storage tanks. With the...

Does a spider spin its web differently in space? What other ways might microgravity affect an arachnid? Pick a topic to research, plan an investigation, and follow astronauts on the International Space Station as they perform some of the...

After background reading on ground and surface water is complete, young hydrologists create a water table contour map. The map displays the elevation of surrounding areas and requires that the cartologists draw contour lines and arrows...

Explore the water cycle with a hands-on earth science activity that prompts pupils to measure the amount of water normally transpired by plants. After they describe the flow of the water cycle and provide examples of how human activities...

Learners construct a model of the hydrologic cycle, and observe that water is an element of a cycle in the natural environment. They explain how the hydrologic cycle works and why it is important, and compare the hydrologic cycle to...

Give young biologists a firsthand look at the process of evolution with this engaging student-centered science investigation. Taking advantage of the rapid life cycle of the Wisconsin Fast Plant, this experiment involves students growing...

How does gravity affect the life cycle of a butterfly? Learn first-hand what types of investigations astronauts perform in space by following along with one of NASA's experiments. Create butterfly habitats in the classroom with specific...

Young scientists learn what it takes for life on Earth to survive with this series of photosynthesis resources. Offering twelve different activities ranging from independent practice worksheets to in depth scientific experiments, this...

Water is common? Not really! Learn how the polarity of the water molecule gives it tremendous properties that make is quite unique in the universe. Learners will understand surface tension, adhesion, and cohesion, as well as why these...

It's commonly known that over 70 percent of of the earth's surface is covered by water, but exactly where did it all come from? Join this short video as it travels back to the beginning of the universe in search of the origins of this...
