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

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

In this activity, learners place cards featuring biological structures in order by their relative size from largest to smallest.

Learners explore the relationship between energy consumption, population, and carbon emissions in the countries of the Americas.

In this activity about weights and balances, learners create their own balance using paper cups. Then, learners explore how to compare the relative mass of objects.

This online interactive has three activities in the NanoLab (press the upper right button): Build, Zoom, and Transform.

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.
