This fun challenge will have students pretending to travel through time and make key decisions about problem solving for the space programs including Mercury, Gemini, Apollo, Space Shuttle, International Space Station, and Mars. They work in teams and are in charge of hiring, public relations, advising the president, and more. After they go through the six programs, they report back to today to debrief their peers and see how they did. After the discussion, students create a timeline.
