“Forms of Carbon” is a cart demo that demonstrates how the nanoscale arrangement of atoms dramatically impacts a material’s macroscale behavior. Visitors learn about the structure and properties of four different forms of carbon. During the program, visitors interact with models of four different forms of carbon. Visitors also observe the conductivity of graphite (using a simple circuit and an everyday pencil) and the hardness of diamond (using a diamond scribe to cut glass).
- Elemental carbon has many different structural forms, e.g. graphite, diamond, carbon nanotubes and buckyballs.
- The forms of carbon differ in their nanoscale structure.
- These nanoscale differences cause the different forms of carbon to have different properties at the macroscale.
- Nanometer-sized things are very small, and often behave differently than larger things do.
- Nanoscience, nanotechnology, and nanoengineering lead to new knowledge and innovations that weren't possible before.
