Jade Diaz, a Heber Hunt Elementary second-grader, participates in a shopping cart race Thursday during a carnival for the second-graders at the school as a reward for their service learning project to collect 2,012 food items from their fellow students for the Open Door Food Pantry. To make the most effective use of the 14-day campaign, which ends Friday, the four second-grade classes each targeted a grade level and spread the word through Power Point presentations that they designed and presented, second-grade teacher Stephanie Holsten said. They also used traditional informational strategies such as in-school print and electronic advertising, she said. The grade level that brings in the most food items will have a school lunch at Liberty Park. A few of the school's staff members have volunteered to take a pie in the face if the goal of 2,012 food items is reached, which at this point seems to be a done deal, said school counselor, Amanda Jackson.
