Hailey Obringer, 6, and Chelsea Davis, 5, patiently await the creation of a cocoon by caterpillars in their classroom at Mercer County Head Start Preschool in Celina. When the butterflies make their appearance, the students will release them as part of the national celebration for the Week of the Young Child, which begins on Monday. Other activities next week include a sing-along with students from area preschools and childcare programs on Monday; Lunch with a Bunch on Thursday, focusing on healthy foods; and a Summer Survival evening on Thursday with parents and children, teaching them valuable tips for summer fun.
