Children delighted at the Mad Science Lab held Tuesday at the Museum of Science and History. Every afternoon, a science program specialist teaches young children about basic scientific principles in a fun atmosphere. Although the performance is highly interactive and family-friendly, toddlers may be startled by the loud, unexpected sounds that are part of the program. Shows are every weekday at 2 p.m., Saturday at 1:15 and 3:45 p.m. and Sunday at 4 p.m. in MOSH’s JEA Science Theater.
