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

This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.

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

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

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 (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.
