As part of the Imagine Science Film Festival, Liberty Science Center is hosting two environmental and science-themed screenings, "From One Bit to the Next" (1pm) and "People of a Feather" (3pm). The first is a collection of 14 short films, each showcasing some aspect of human existence, from a microscopic to a macroscopic level, and examining the connections within those levels. The second is a full-length feature documenting seven winters in the Arctic and the reliance of the people there on the down of the elder duck. A short film on the hunt for the Higgs Boson particle will screen beforehand. Ages 2 and up.
