ix Acknowledgments Gustavo Hernandez our magnificent co-coordinator at the Watsonville Environmental Science Workshop was a genuine treasure in preparing troubleshooting honing and giving fresh perspective on this set of projects His enthusiasm for helping kids to learn from these sorts of projects is unbounded The hundreds of Watsonville kids served by the Science Workshop were also invaluable in testing and giving feedback I trust they enjoyed building the projects as much as I did Gustavo and Fabiola Pizano also helped set up and pose for the photos after hours Thanks to Paul Doherty for checking the science content All remaining errors are my own Thanks to Jerome Pohlen at Chicago Review Press for being an editor with a genuine human touch perhaps one of the last Thanks to Rory for the laptop on which this was written Like folk tunes science projects such as these are continually being changed and improved upon as they pass hand to hand shop to shop I’ve given credit at the end of each project section if I can recall where I picked up the idea whether or not that was its true origin
