The 2014 YSDE will have a final meeting April 26-28 to wrap up work and present research. This meeting will take place at Canaan Valley Institute Research and Education Center near Davis, WV. A colloquium will be held Monday morning, April 28th, at 10AM, and a poster version of each team’s work will be hosted on this website. Family, friends, and the public are welcome to attend the presentations.

During their last evening in Green Bank, YSDE students worked in teams of 3 or 4 to devise a package that would (hopefully) carry a Pringle chip through USPS first class mail to the camp director’s home without the chip getting broken. The main factor was final condition of the chip, and packages were weighed upon receipt to distinguish the lightest, most efficient packaging in the event of multiple successful deliveries.

After five days of hard work and play, this spring YSDE crew heads home today. They spent the morning analyzing and interpreting their data, making plans for work yet to be done, and looking forward to coming together again in late April to wrap up research and present their results to peers and advisors. Thanks to Sue Ann Heatherly, Kathryn Williamson, and the NRAO staff for hosting and helping with this session, and thanks also to Joe Allen, Rachel Rosen, and Aaron Sutch for traveling to Green Bank to advise the student research projects. NYSF is grateful for the opportunities to work with such dedicated science professionals. We also appreciate the dedication of the teachers and students willing to make time in their busy schedules to come together for this experience. More to come soon as the closing weekend and colloquium approach…
Above, Team Becquerel gathers in the science center on their last morning in Green Bank.
With tomorrow’s departure approaching, most teams spent the morning gathering their last data for the week. The astronomy groups forged ahead with data analysis, Team Lyell made up for lost time after technical difficulties with the ground penetrating radar, Team Becquerel improved their experimental design for further tests, and Team Jacquard made some preliminary conclusions with more detailed analysis to come.
After four days of mental focus on research projects, today’s seminars offered some relaxing activities (crochet, Zumba, board games) in addition to more science-oriented options. Continue reading
Today we finished collecting data for our project on benefits and disadvantages of multiple methods of cooling hot components. We collected data for liquid cooling and air cooling. At a glance, the data suggests that liquid cooling is better, but we have yet to analyze the data more in depth. We measured the difference by using a thermal imaging camera for the air and liquid cooling on the simulated CPU, and a computer script for measuring the temperatures for the actual CPU and GPU. Since we finished collecting data today, we will be able to analyze our data all of tomorrow morning before we have to depart. We hypothesize that liquid will cool more effectively than air, and will find that out tomorrow.
The first picture shows the Reber telescope. Reber was one of the fathers of Radio Astronomy, and built the telescope in his own backyard! The second shows NRAO public outreach coordinator Kathryn Williamson giving a talk about Newtonian gravity and how students understand it.
Today, Team Reber began analysis of some of their data which we received from the 20 meter radio telescope. Many of the observations were submitted the day before and were available to the group for analysis using excel.
Today we explored the Harborville Cemetery. We used the Ground Penetrating Radar (GPR) to survey the land. When we went over the graves, the monitor showed parabola showing how deep they were in the ground. We also found an abundance of bedrock that sloped upward indicating an anticline. When we explored the forest surrounding the cemetery, we found Quaternary unconsolidated sediments and Devonian sandstone and shale. While scouting the area for outcrops, we collected sandstone, limestone, and shale that we will examine at a later date.
To survey the land we used three different antennas. We used the 50 MHz antenna which reached deepest into the ground but showed least resolution. The 100 MHz did not go as deep, but gave us a better resolution. The 200 MHz gave us the best resolution but only a few meters deep, unlike the other antennas. We also intentionally created an interference pattern with metal keys so that we would understand if we read any other interferences.
