Daniel White, a University of Houston-Victoria assistant professor of biology and program coordinator for the UHV biology and chemistry programs, shows Stroman Middle School students a video of a rollercoaster in UHV’s visualization theater Tuesday during Stroman STEM Academy’s field trip to the campus. About 170 students in the Stroman STEM Academy visited the UHV campus Tuesday and Wednesday and met with UHV biology, computer science and mathematics faculty to learn about STEM subjects. Throughout the two days, the students participated in demonstrations including extracting DNA from fruit, chemistry reactions, computer robotics and magic tricks involving math.
