About the Authors

The curriculum materials presented here were produced by J. Heffernan and R. Plesser. They are based on material developed by Ronen and presented at Forest View Elementary in Durham, NC by Ronen and by students from Duke University, and were first written up by John in the summer of 2003, with support from the NASA Space Grant program. This version was supported by a Kenan Fellowship. We thank many teachers and students who, in using the materials, helped us understand where more work was needed. Particular thanks go to Lisa Byrd and Rhonda Swaringen, who helped produce a previous version for the Durham Public Schools.
