Jasmine Ripley (left) who studied the effect of day/night on the strength of radio waves, received a 4th place ribbon at the Alamo Regional Science & Engineering Fair. Jose Rodriguez (tall middle) built a Rubens tube and used it to study the the pitch of sound and its wavelength at different frequencies. Diego Aranda (right) looked at different lip balms to see which held up the best (using sliced apples). Photo courtesy of Jason Siptak.
