This activity introduces learners to the structure and properties of carbon nanotubes.

In this activity, educators can demonstrate how the nanoscale arrangement of atoms dramatically impacts a material’s macroscale behavior.

In this activity, learners make "totally tubular" forms of carbon. Learners use chicken wire to build macro models of carbon nanotubes.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

In this activity, learners construct and launch rockets using simple materials and their understanding of chemical reactions.

Learners take on the role of environmental engineers as they design water filters.

In this activity, learners separate the components of Gatorade using a home-made affinity column.

Learners will build and experiment with their own windmills made from simple household materials.

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.
