Effective Strategies for Generating Awareness and Interest in Science and Engineering among Underrepresented YouthNative Americans are seriously underrepresented in science and engineering. To addressthis concern, the authors have created a flexible two-component workshop that usessubmarines as a vessel to introduce basic science and engineering concepts.Submarines must resist considerable pressures, resist corrosion, be able to move in threedimensions while mostly navigating blindly, and be able to support life for months at a time.Science and engineering basics that are needed to address those concerns are introduced andexplained in the workshop, such as pressure and strength, controls, environment, and productdevelopment.One component of the workshop is lectures that incorporate electronic slides and short movies,where each short movie demonstrates a concept. For example, one movie shows how inflatedballoons shrink when submerged, due to the water pressure increasing at depth. Another movieshows animations of how submarines are able to move in three dimensions under water.The other component of the workshop is hands-on activities. The hands-on activities start withletting participants control a remote-controlled submarine in a swimming pool. Next, theparticipants assemble tethered remotely-operated submersibles according to a fixed design frompre-made kits. Finally, a design challenge with a scored competition at the end is issued, whereparticipants receive a large collection of parts to build their own design of tethered remote-operated submersible. The competition consists of several timed navigation challenges, such astraversing a pool while submerged the entire time, then traversing back while surfaced the entiretime.The workshop has been given to Native American middle- and high school students five times intwo states, and is about to be given to incarcerated youth at a local juvenile detention center.Written surveys are given before and after the workshops, and the results consistently show alarge increase in the participants’ interest in pursuing careers in science and engineering.
