What Kind of Shower?!: Week 3 (July 14-18) On July 17th the sky will have a shower - a Perseid meteor shower! While the best views from earth will occur later in August, this annual meteor shower is scheduled to start this week, when our Earth passes through the Comet Swift-Tuttle debris trail. As chunks of rock from this comet trail enter our atmosphere, friction from the resistance of the air causes them to burn up, and streaks of light we often call shooting stars glimmer across the sky. How does air resistance and the force of gravity burn heavy rock? Campers will dissolve pretend meteors they make from scratch, design and race parachutes, even wish upon a star to demystify the magic of meteor showers.
