Bobby Farlice-Rubio of the Fairbanks Museum in St. Johnsbury will be at the Greensboro Free Library on Tuesday July 17th at 10am. He will combine two of his wonderful programs into one great presentation in keeping with the summer reading theme, "Libraries Rock" celebrating music and geology.

"Catch this Wave! Communicating with Audible, Visible and Invisible Energy!" Our voices use sound waves to speak words to each other, but what if we're too far apart to hear each other shout? In this exploration of communication, we'll discover how different kinds of waves, like sound, light, and even invisible radio can be used to send messages to the farthest corners of the universe. Or maybe just to send your friends an emoji! Students will become familiar with concepts relating to wavelength, frequency, and amplitude.

"And The Mountains Should Crumble to the Sea" Have you ever wondered what our mountains might have looked like when they were tall, pointy volcanoes? What happened to them? Why do our driveways and back-roads seem to "disappear" every spring? How do canyons form, and why is there so much sand on the coasts of the world and at the bottom of the ocean? In this learning deluge, we will explore all of the glacially slow or catastrophically rapid ways in which water and erosion shape our world.

This program is geared for youth ages 6+. Free and all are welcome. Bring instruments for extra fun!

The presentation will be on Tuesday July 17th at 10am at the Greensboro Free Library. Contact Emily Purdy, Youth Services Librarian, at 533-2531 or greensborokids@gmail.com for more information.
