Astronauts, we have a problem! Grades 7 & 8 activity. Students imagine that they are astronauts on a mission gone awry with a faulty control board on their shuttle and the threat of never being able to get back to Earth! A group of friendly aliens offers their help in fixing the problem, but they want to make sure that their human friends can actually help in the mission. They put the astronauts to work by making them solve problems and crack their alien code!
