(CNN) -- Children were injured when a school bus overturned in eastern Kansas on Wednesday afternoon, Kansas Highway Patrol spokesman Howard Dickinson said.
The bus -- carrying 36 girls and a driver -- slipped down a hill as it came around a curb and came to rest on its side in Bonner Springs, Dickinson said.
The University of Kansas Hospital received nine patients from the crash, said spokeswoman Jill Chadwick. Of those, three were admitted, and the rest had been discharged, she said.
The injuries ranged from concussions to potentially more serious brain trauma, a spine injury and a leg injury, she said. The children tumbled inside the bus and suffered serious bumps and bruises, Chadwick said.
The crash happened just before 1 p.m. on southbound Kansas Highway 7, CNN affiliate KCTV reported.
