This paper rocket activity is part of the NASA Rocket Educator Guide (https://www.nasa.gov/audience/foreducators/topnav/materials/listbytype/Rockets.html) that emphasizes hands-on science, prediction, data collection and interpretation, teamwork, and problem solving. Students will construct small “indoor” paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw. Students will then test their designs through trials, gather and analyze data, and then try to improve their rocket design to get greater distance.
