Yesterday was wear your favorite hat day at JYMS! The students were ready for NDeRC NANO, and although I could not see them, they all had their thinking caps on! I shared our nano presentation with Walt Buras’ eight grade classes (3) yesterday, and Becky and Michael will visit with them tomorrow. Unfortunately, I could only give abbreviated version for the first two classes because of the bad weather – a tornado warning which lasted almost two hours. Everyone had to take cover for safety. However, once the warning was lifted, I was able to give the afternoon class the full version, and it turned out to be a lot of fun! 
After the last class of the day, several students stayed behind to ask more questions. During class, we used the AFM to scan the surface of one of the samples that NDeRC purchased from Nanoscience – an IC chip. The one shown in this post is a RAM (random access memory) chip. Each element consists of two rounded squares with a hole in the middle, separated by a groove. Together, the rounded squares and the groove consist of one memory cell. The holes would connect to transistors below them. Gates lie below the grooves. The lower images was previously obtained. The top image was taken during class yesterday!
