Here are a few things I've created that I've shared at conventions and meetings that you may be interested in. Feel free to use them with your students and share them with colleagues, but they must all remain strictly non-commercial.

A poster presentation on our soda bottle rocket labs, presented at AAPT in 2009. Images, description.

A powerpoint presentation on research correlating scientific reasoning skills to student performance, presented at AAPT in 2009.

Full details on a Multipurpose Device for Exploring Electric and Magnetic Fields as entered in AAPT's 2009 apparatus competition.

An annotated powerpoint on "An Introduction to the Cycles of Modeling." presented at NSTA 2007. It includes examples from modeling physics and modeling chemistry.

At the 2003 summer AAPT meeting I offered a half-day workshop on a model based approach to energy instruction. I have brought together a number of materials for a model-based approach to energy instruction,

"Double Slit Diffraction Gratings" This is a .pdf file which, when printed out with a 600 dpi laser printer on transparency material, provides seven different slit widths.and I offer them here for you to check them out.

"Optical Art Projects in Physics/Physical Science" I presented this at the 1999 NSTA convention at Boston. It is a .pdf file that contains a number of diagrams and suggested activities.

All of the mechanics materials from the modeling project, including materials for chemistry and physical science, can be downloaded from the Arizona State University Modeling Project site.

If you have any trouble downloading something, contact me and I will send the materials to you as an e-mail attachment.
