Comments and anecdotes about the event:
I used the NSN Sun Poster to talk about the features on the sun and what is going on inside the sun.  I presented the solar system planets that are scaled to the poster and we discussed what the planets were like and talked about the definition of planet vs. dwarf planet.  I told them a little about the New Horizons Mission and the DAWN mission.  Then we did the pocket solar system activity.  As usual, it was a big hit and opened a lot of eyes to the distances in space.
