Today we displayed our projects to guests and judges. My booth was pretty busy. People were curious how to know how to build a heart-beat sensor using an Arduino and a Pulse Sensor!! The Assembly Member from Milpitas, Alex Lee, also came to see our projects. And so did the district director, Anurag Pal. We have the common last name ... and for that he gave me his business card :-) The MHS Science Olympiad team had a cool project ... a rubber band powered plane that keeps flying in circles ... and comes down as the rubber band unwinds. Its an example of potential energy getting converted to kinetic energy. Here is the video MUSD posted my project on their website. Here is the link
