Explore molecule shapes by building molecules in 3D! How does molecule shape change with different numbers of bonds and electron pairs? Find out by adding single, double or triple bonds and lone pairs ...

Faces - A face is a flat surface on a 3D shape. For example a cube has 6 faces. Edges - An edge is where two faces meet. For example a cube has 12 edges. Vertices - A vertex is a corner where ...

Interestingly, Princeton University engineers have created innovative 3D structures from a single piece of material by combining the art of paper cutting and folding. They have developed 3D structures ...
