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

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

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

Electrolysis is the breakdown of water into hydrogen and oxygen. This Exploratorium activity allows learners to visualize the process with an acid-based indicator.

In this activity, learners use geometry to predict the shape of carbon. Learners twist and attach chenille stem pieces that represent bonds between different carbon atoms.

In this activity, learners explore the question "What is paper?" Learners discover the processes and materials required to make paper while experimenting with different recycled fibers and tools.

In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.
