The newest, most transformative realm of scientific discovery and invention is happening at the nanoscale, many times smaller than the microscopic level. To celebrate this exciting science, we invite teachers, students, and their families to be a part of a free, educational festival called NanoDays. This public event offers engaging, hands-on activities to explore the miniscule world of atoms, molecules, and nanoscale forces. Participants will get to: Construct their own nanomaterials! Investigate how ink jet printers work! Experiment with ways of bending light to make objects invisible! Chat with UNL faculty and graduate students about current nano research! There will also be prizes for the first 100 student attendees who visit all of the ten interactive demonstration tables, and a nanoscience education kit awarded to the elementary and middle schools with the most student attendees. NanoDays is part of a nationwide festival of educational programs about nanoscale science and engineering sponsored by the NISE Net program and funded by the National Science Foundation (NSF).
