Explore rocks, minerals, and fossils with the Gem, Mineral, & Lapidary Society of Montgomery County and the Calvert Marine Museum. The flourescent mineral display will be enLIGHTening and visitors may get bitten by the fossil hunting bug when they see the shark’s teeth display. There will be lots of hands-on activities. You can even make your own pet rock!
