The Earth and Space Science Laboratory (ESSL), located next to Lincoln Elementary School, has information on its website for Summer Planetarium shows which begin on June 29th and run through August 5th. Cost is $4.00/person if you buy your ticket at the door. Buying on-line costs an additional dollar.
Also, I got this email from Find Out First, (the FCPS website that emails you information about happenings within the public school system) regarding summer camps at the Earth and Space Science Laboratory:
