SUNBURY, Pa. Weis Markets on Tuesday announced the introduction of its Weis Mystery Tours, a new field trip program that will help third- and fourth-graders learn about the fundamentals of nutrition.

During a 90-minute tour, students will play the role of Weis Detectives searching the store for clues to solve the Case of the Missing Energy. Weis Markets director of lifestyle initiatives, Karen Buch, developed the store-touring program, which is offered at no charge.

"We're scheduling tours through the 2010-2011 school year for both public and private schools as well as for groups of home-schooled students, boys and girls scout troops, and church groups," Buch said. "We believe these tours will support the fight against childhood obesity."

The tour program reinforces USDA's MyPyramid nutrition principles with a focus on the importance of making sensible food and activity choices. Trip amenities include detective gear, on-line classroom support materials, healthy snacks and take-home packs for both students and parents.

Tour locations include 50 select stores throughout the grocer’s five-state market area.
