Eitan Smolak skips over the drawing his mother, Aiyan, works on during the 6th annual Chalk Art Marathon at Tanque Verde Elementary School, 2600 N Fennimore Ave. in Tucson, Ariz. on November 16, 2022. After a two year hiatus, due to the Covid-19 pandemic, the chalk marathon returned in honor of Tracey Jones, a parent who enjoyed the event. According to Alicia Marrano, art teacher, the idea is to bring science and art together. Participants pay $10.00 for a square. The funds go towards buying supplies for the day and for science and art tools for the classroom. This year the event was organized by the school's Parent Teacher Group.
