The Flagstaff Festival of Science returns to excite and inspire the next generation of scientists and offer educational activities for science lovers throughout the community.

The free 10-day festival’s theme is “Making Waves.” From ancient oceans to disappearing springs, Flagstaff’s dark skies to the Martian surface, giant armadillos to mountain lions, Earth’s lava to Titan’s polar seas, the 2012 festival is making waves across the universe from Sept. 21-30.

A local favorite from the festival is helping kick things off tomorrow. The annual NAU Science and Engineering Day takes place from 1-4 p.m. Saturday, Sept. 22, at the High Country Conference Center and at the Wettaw Biology/Biochemistry buildings. The event promotes youth learning and interest in science with hands-on science experiments, creepy crawlers and magical chemistry shows. Kids of all ages are invited to learn about rockets, robots and the rumblings of northern Arizona’s seismic activity.

All events during the festival are free and open to the public. Visit the festival’s website to print your passport for activities.
