Our Science Projects

Your Tax Dollars at Work: The National Science Foundation's Small Business Innovation and Research (SBIR) program generously granted us support to develop science curriculum materials.

One project integrates physics and mathematics through data analysis and Fathom or Logger Pro. A Den of Inquiry is the first publication to come from that project. More are in preparation, even though it takes longer than we thought.
Integrating Physics and Mathematics >>

In another project, we're developing web-based simulations of the nature of science. We're between phases right now, but the prototype is really interesting and we hope to get more funding soon!
