Backpacks In Space

Students at MorrisonLabs are finding out what their backpacks weigh on earth so they can determine what the backpacks would weigh on the other eight planets of our solar system. They also find the weight of their backpacks on our moon, sun, and a white dwarf. To do this students multiply the surface gravity of a planet by the weight of the backpack on earth.
