A chirality teaching tool includes a central sphere representing a chiral carbon atom, and four projections representing substituents bound to the chiral carbon atom. The central sphere includes two hemispheres rotatable relative to each other. Each of the four projections forms an angle of about 100 to about 120 degrees with each other projection on the same hemisphere, and each projection is capable of forming an angle of about 100 to about 120 degrees with each of the two projections on the other hemisphere. A message indicating the type of chirality (e.g., R or S) is visible from outside the central sphere and displayed on or below the outer surface of the central sphere. The message changes when relative locations of two of the four projections are exchanged by the rotation of the two hemispheres 180 degrees relative to each other.

A system of construction that uses a discrete repertoire of elastic modular units that interconnect forming assemblies of diverse curved geometries applicable at any scale. Each modular unit is formed with linear elements with less than infinite elastic modulus. The modular units connect to one another under tension creating structural networks that have stored elastic potential energy. The linear elements may be formed of carbon based composite materials and their future permutations, including smart materials. The modular assemblies created using this system have application in terrestrial, space and aquatic environments and as an educational tool.
