Season 2 episode 6 student video worksheet. From the History Channel's website:
"Scientists have no idea what it is, but Dark Matter and Dark Energy make up 96% of the Universe. Dark Matter is everywhere. It passes through everything we know on earth at billions of particles every second, yet no one has ever gotten a direct detection of this mysterious dark substance. An even more bewildering force is Dark Energy, which is rapidly pushing apart our Universe. Discovered only ten years ago, scientists are struggling to comprehend its unusual characteristics and answer the ultimate question; what is the fate of our Universe? Using cutting-edge computer graphics watch as the universe is brought down to earth."
This video activity can be used to review concepts in Astronomy Unit X "Cosmology and Life in the Universe" or in the Earth/Space Unit XIV "Stars and Galaxies." This episode explains the origin of dark matter and dark energy; what they could be made of and how astronomers can infer their detection. The episode also ties in the fate of the Universe with dark energy.
