Preschoolers showed off their new playground to a number of dignitaries, including Gov. Norm Bangerter, Tuesday at the George S. and Dolores Dore Eccles Early Childhood Development Lab School. At Salt Lake Community College, the new lab school will provide quality day care for the children of SLCC students, many of whom are single parents, and will offer a facility to train qualified child-care-center operators and professionals. The lab school, designed to care for up to 100 infants and preschoolers at a time, has seven child-development classrooms, an infant nursery, a nutrition center, office space, an observation booth and playgrounds.
