Learn how gravity can be described as the curving of spacetime, according to Einstein’s general theory of relativity, in this video from NOVA: Black Hole Apocalypse. Computer animations illustrate the concept of warped spacetime and how objects “fall” along a curved path. Use this resource to visualize the abstract concept of spacetime and to illustrate the progress of scientific thought. This resource is part of the NOVA: Black Hole Apocalypse Collection. Support materials include: Background Reading, Teaching Tips, and Discussion Questions. This resource was developed through WGBH’s Bringing the Universe to America’s Classrooms project, in collaboration with NASA.

This narrated animation from Interactive NOVA: "The Secret of Life" shows the double helix structure of DNA and how the molecule replicates. The segment illustrates how DNA "unzips" to form templates for the new strands and how complementary nucleotides bind together like the rungs of a ladder. This
