In this activity, learners investigate the properties of graphene and graphite. Learners use tape and graphite to make graphene and learn that graphene is a single layer of carbon atoms arranged in...

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed. Learners investigate the history of piezoelectricity, how it's used, and...

In this activity, educators can demonstrate how the nanoscale arrangement of atoms dramatically impacts a material’s macroscale behavior. Learners investigate the structure and properties of four...

This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model. Learners will explore what cosmic radiation is and where...

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon. Learners role play as miners, power plant operators, car drivers, and home...

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials. Learners group together and link arms or hold hands to form chemical...

This activity introduces learners to the structure and properties of carbon nanotubes. Visitors learn how the carbon atoms are arranged in a carbon nanotube, and that nanotubes are extremely strong...

In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how...
