This is what I did last weekend
It was AWESOME. We spent months preparing although Lena Lee and Cathy Schoonmaker did most of the work. I designed some of the science activities for kids, called community centers to arrange buses, and helped put up flyers. On Friday I ran 32 fifth graders through a hands-on science activity comparing native plant diversity in native and non-native plant communities. I even had them make and analyze bar graphs to draw conclusions. On Saturday I staffed the nature illustration table having kids draw bugs as accurately as possible and took a two hour shift at the story telling booth.
It was GREAT! Over 2000 people came on Saturday and all the kids had a blast. The event was incredibly diverse with a ton of first time park goers. We really fulfilled the mission of an urban park with this event, introducing thousands of people to THEIR national park.
