Our chemical crystallization gallery contains time-lapse cinemicrography sequences that capture the crystallization, dissolution, sublimation, or melting of purified chemicals either in the solid form or dissolved in a suitable solvent. The pond life gallery features full-motion videos of minute creatures found in North Florida's ponds and lakes. Included are a wide diversity of organisms such as hydra, protozoa, rotifera, nematodes, and crustaceans. Use the link below to navigate to the digital movie galleries. Chemical Crystals - Chemical compounds can exist in three basic phases, gaseous, liquid, or solid.
Gases consist of weakly bonded atoms and expand to fill any available space.
Solids are characterized by strong atomic bonding and have a rigid shape. Most are crystalline, having a three-dimensional periodic atomic arrangement. Some, such as glass, lack this periodic arrangement and are noncrystalline, or amorphous. Liquids have characteristics that fall in between gases and solids. This cinemicrographic collection presents time-lapse movies of various chemical compounds as they change physical states.
