The NorthStar sample lessons require the free Adobe Acrobat Viewer which is available for download by clicking on the icon below. Some have also been provided as a Word document or movie.

I can not post full lesson bundles for each given lesson online because

1. these lessons are stuffed using Stuffit (www.stuffit.com), and I do not want to require the visitor to have to first install Stuffit and then figure out how to use it.
2. many of our lesson documents and/or supporting materials are created using additional or specialized software (e.g. Mathematica and Geometer's Sketchpad for math and ChemLab for chemistry), and I can not assume nor require that the visitor have this special software in order to simply view sample lessons. For this reason, I have to post simple and stand alone lesson documents that will give the visitor a sense of the overall lesson resource.
