 V9: How Big Is the Universe?Based partly on the short film Powers of Ten, this program surveys distances and sizes of things in the universe. Starting with familiar and ordinary things on earth, students move to progressively more distant astronomical objects: the moon, the sun, the solar system, nearby stars, the Milky Way galaxy, and clusters of galaxies. They use parallax, "radar," to determine distance and comparing brightness of objects. Students write their complete galactic address, make a parallax distance finder, find the distance to the moon, and expand the universe.Our Price: $12.50 |
