This is Part 1 of the All-Star Series. Recently, USA Today came out with their annual All-Academic team, showcasing 20 of the most talented and accomplished high school seniors in America. I was able to catch up with a bunch of them, interviewing them about their high school accomplishments, asking about their college admissions experiences, and begging them to share some of their nuggets of wisdom with y'all. Read my introduction post.
Quick facts: Meredith just graduated from Fairview High School in Boulder, Colorado. She will be attending Harvard in the fall. She graduated with a 4.0 GPA (unweighted out of 4.0).
Accomplishments: She built a computer-controlled electromagnetic shaker to study the Brazil Nut Effect, or why the larger pieces of granular material rise when shaken, winning the Intel Foundation Young Scientist Award and placing ninth in the Intel Science Talent Search; Siemens Competition semifinalist; varsity cross-country and track captain and all-state in both; AfricAid Club co-founder and co-president; National Honor Society treasurer; Knowledge Bowl team; French Club treasurer; Volunteer Mafia board member.

Tell us about your research on the Brazil Nut Effect? Any ground-breaking discoveries? Explain it to us as if I were 8 years old. Cuz if not, it'll probably be way over my head.
Well, the Brazil nut effect (BNE) is an interesting phenomenon that occurs in granular materials. Basically, when a container of mixed-size granular particles is shaken the larger particles end up rising to the surface. The name was inspired by a can of mixed nuts. When you pop off the lid, all of the large Brazil nuts are on top. The BNE is actually a fairly common phenomenon.
Real world examples include avalanches, rock slides, and really anything involving granular particles. My research was essentially an attempt to study the BNE in detail and determine what mechanisms are behind it. In the end, it seems that it is produced by a combination of convection and air pressure.
