In Lancaster this weekend you might want to check out the North Museum of Natural Science & History. This Sunday, March 1st, is Family Science Sunday at the North, featuring Jack Hubley, the host of WGAL-TV's "Wild Moments." Hubley will be giving presentations on how to tell the difference between venomous and non-venomous snakes.
The North Museum is also currently featuring an exhibit called Arctic Adventure (through May 15th), and interactive and artifact-based exhibit about the unique nature of the earth's polar regions. Permanent exhibits include a dinosaur gallery, the Hall of the Cosmos, and a live animal room. And don't forget they have some pretty cool planetarium shows as well.
Newer to Lancaster is the Lancaster Science Factory, a hands-on, interactive museum that is especially appropriate if you have younger kids. Through April 14th they have a pretty cool exhibit called K'NEX: Building Thrill Rides.
And don't forget the Harsco Science Center at Whitaker Center for Science and the Arts in Harrisburg. This is the largest science center/museum in the area and has a great selection of temporary and permanent exhibits. Currently running is How People Make Things, as well as Forces of Nature. There are also plenty of permanent exhibits as well as the Select Medical IMAX Theatre.
Always something to do in Central PA, so take the family out this weekend and get your science on!
