We read short stories to move forward our investigation on what is science fiction. We been looking at life on other planets. Some of the things we have been looking at is alien D.N.A. coding and deciding whether it compatible with humans. We also looked at a multiple sun planet. We look at life forms who live their whole lives with invisible and able to mimic voices. We have seen way different life forms of aliens are similar to humans and different. I think one of the big ideas is deciding how closely relate alien life forms would be to humans. Would they have same basic essentials as human are require more or less? Would they need oxygen, water and food? Could they possible be able to live off the sun solar energy? Are they threatening or peaceful?
