Hi Spencer - Our Anchorage office doesn't often host tours or open houses - occasionally we will for a university class or school group. If you're in Fairbanks, the University of Alaska Geophysical Institute runs summer tours that cover a lot of different programs, including AVO: https://news.uaf.edu/geophysical-institute/ The "In the company of volcanoes" blog (not written by anyone affiliated with AVO) has a lot of activities, some of which are suitable for four year olds: http://inthecompanyofvolcanoes.blogspot.com/p/blog-archive.html Glad to hear of more scientists! cheryl -------- Spencer Shroyer wrote: Hi! My 4YO twins are starting to get more interested in science / weather / volcanos and I didn't know if y'all ever do tours or open houses? Thanks in advance!
