Surrounded by her classmates, Kaylee Smith, 5, a student in Maria Martinez's class, takes a turn at shoveling dirt on the roots of a newly planted orange tree during the Earth Day celebration at the Spring Hill Head Start campus. As part of Tuesday's observance, the faculty and staff worked with students by teaching them the importance of recycling, saving energy and planting trees. Head Start is a federal program that promotes school readiness for young children from low-income families. For a video report from the event, go to tbtim.es/2ba.
