In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.

In this multi-part activity learners examine non-point water pollution.

In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

Learners compare the properties and solubilities of Styrofoam (TM), ecofoam packing peanuts, and popcorn. First, the solubility of each substance is tested in water.

In this activity, learners will engineer a roof using simple materials to protect a construction paper person from a rainstorm.

In this activity, learners test and compare the physical properties of thermoplastic polymers. Learners compare different plastics based on their color, degree of transparency, texture, and density.

In this data activity, learners will explore shipwrecks from four National Marine Sanctuaries on the West Coast of the United States.

This activity offers learners and their families several ways to raise their awareness together about home water.

In this activity, learners discover why only some types of plastic can be recycled.

Agriculturalists have long considered mushroom growing a challenge, largely because you need a piece of benchtop equipment known as a laminar flow hood.

In this activity, learners interact with a 3-D model of a watershed to better understand the interconnectedness of terrestrial and aquatic environments.

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.

This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.

In this design challenge activity, learners explore the concept of biomimicry by using a natural organism's special features to design a new human object.

Learners will follow a specific process to make their own paper using scrap paper, newspaper, or junk mail.

In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.
