Hundreds of people have signed an online petition in hopes of keeping the Fernbank Science Center from closing.
Parent Kate Teague said she plans to attend a public hearing Wednesday to voice her concerns.
Members of the DeKalb County school board are recommending that the Fernbank Science Center and its planetarium be closed to help save money.
The center, near the Fernbank Museum of Natural History, costs $4.7 million annually and employs 56 people. The district is facing a $73 million deficit and is considering cutting teachers and school days to make up the gap.
A public hearing on the proposed budget is scheduled for 6 p.m. Wednesday at the school system headquarters in Stone Mountain.
