This exciting unit opens when your class receives a simulated binary-coded message from space. As they begin to decipher it, a journey through our own solar system and beyond begins. Activities explore how other star systems and their planets may have formed, and model what scientists have inferred about the "life zones" of different types of stars. Students model size and distance, then design tourist brochures for travel to the planets of the solar system. Later they respond to the original message and create science fiction stories. Students can evaluate scientifically the possiblities for extraterrestrial life. Messages from Space builds upon a collaboration done with the SETI (Search for Extra-Terrestrial Intelligence) Institute.
