Roller coasters, water sheds, radio, and TV! Today was a whirlwind of a day! Big thank you to EGS (Environmental and Geotechnical Specialists) for spending their morning with us! Led by Audra Hayden and Lauren Beckwith, civil engineers, and Elon Yates, President of American Society of Civil Engineers, at FSU College of Engineering, our SciGirls learned all about the ins and outs of a civil engineer! Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including works such as roads, bridges, canals, dams, airports, sewerage systems, pipelines, and railways. After their introduction, our girls started engineering! Their first task was to engineer roller coasters using pipe insulation, tape, wooden blocks, paper towel tubes, and a marble. We discussed support, velocity, potential and kinetic energy, acceleration, and friction. Their goal was to create a coaster with 2 loops, 2 hills, and 1 jump! All girls succeeded! After coasters, we switched to water sheds! A water shed is a place for water/runoff to be stored for purposes of floods, from higher elevation to lower. Using similar items as before, girls had three steps to take to build their water sheds. First, they needed to make the topography below their surface, then, place the surface (a tablecloth) over their topography structures, and lastly place building/houses on their land. Then, it “rained!!” Each group successfully collected their “rainwater” in watershed “pools.” After a huge thank you to EGS, we walked to wFSU for Media/Communications Technology fun! Thanks to Kim Kelling, Director of Content and Community Partnerships, Suzanne Smith, Executive Producer for Television, Paul Dam, Production Manager, and the staff at wFSU for showing our girls all about public media. Some of our girls went off into the radio world, where they recorded a discussion concerning their hobbies, music, challenges/interests in science, and then they talked about their beloved pets! The rest of the girls made a television news broadcast about their experience thus far in SciGirls Camp! Both portions, radio and TV, will be broadcasted Friday night at the reception at wFSU. All in all, today was another wonderful day!
