A student adds pennies to an aluminum foil bot as part of a Penny Boat Challenge held in conjunction with the Naval Air Station Oceana Outdoor STEM (Science, Technology, Engineering and Mathematics) Laboratory, Sept. 20. This challenge not only leads the students to think about the basic shape and design of the boat so it can float on water, but strategy and skill also come into play when they start adding the weight of the pennies. The free event, which has been held nearly every year since 2016, allows 5th graders from Virginia Beach City and Chesapeake Public Schools to receive an exclusive sneak peek of the Air Show performances, including the U.S. Navy Flight Demonstration Squadron, the Blue Angels and the F-22 Raptor Demonstration Team; vendor booths and activities; and numerous STEM Laboratory exhibits. This year's theme is "Inspire. Educate. Soar!" (U.S. Navy photo by David Todd)
