In this activity from the Jet Propulsion Laboratory, students develop an understanding of the first helicopter to travel the surface of Mars for purposes of gathering information in terrains otherwise inaccessible to traditional rovers. The host, Ota, from the Propulsion Laboratory, provides insight into the science behind the helicopter design and the contributions it is expected to make with understanding the Martian landscape. Not only is her delivery engaging and age-appropriate, but also she provides tools for participants to construct their own paper helicopter using materials found around the home (paper, pencil, and scissors). In addition to the video, the resource offers step by step instructions with photos, along with suggestions for varied trials (manipulating the design to test different prototypes). The helicopter created for this review was simple to construct (using a hand-sketched template), and successfully completed rotations during the trials.
