Izaiah Lopez, Nathaniel Talamantez, and Gregory Hayah of Cesar Chavez High School competed in the National American Indian Science and Engineering Fair in Albuquerque, NM   during Spring Break.   The three boys are former students of Gila Crossing Junior High School in Laveen, Arizona.  Their former teacher, Karen McQueen invited former students to participate in the National AISES Conference (American Indian Science and Engineering Society).    

Lopez’s project was entitled, “Alternative Power Energizing Machines fuel cell” (A.P.E.M fuel cell).  He wanted to determine if temperature will change the efficiency of a Polymer Exchange Membrane (P.E.M.) fuel cell.  He tested at 90 degrees, room temperature 75 degrees, and at 50 degrees. 

Talamantez’ s project was named “Wing Perfection.”  He built an apparatus that when wings were attached, it would be free flowing.  When wind was introduced the number of rotations per minute were counted, recorded, and analyzed to determine which winglet is the most efficient.

Hayah built a robot to use as a test instrument and constructed a parabolic antenna to determine if it would enhance the speed of the robot.  He tested the robot over different terrains to determine the results.  His project was entitiled “Rockin’ Rollin Robots.” 


 Lopez won 1st place in his division, and an I-pad from the Raytheon Corporation.  Talamantez won 1st place in his division,  with a $90 cash award. Hayah won 2nd place in his division and a $250 cash award from the Winds of Change Excellence in Communication Award.
