This site was inspired by the
Perimeter Institute of Theoretical Physics (PI)

and
Physics Education Research (PER)

This goal of this site is to provide lessons that...
1) are ready-to-use and cheap - usually free
2) deal with 'modern' physics - i.e. 1900 - 2010
3) easy-to-use by teachers - teachers can learn the essential physics while checking out the lesson
4) are appropriate for high school students - correct level and curriculum connection
5) involve the students as active learners - not passive recipients.

All the materials on this site are available to anyone who wants to use them or modify them. Most lessons provide three files that are ready to copy, print and modify. There is an Interactive Lecture in a PowerPoint format, a worksheet for the students and a teacher's guide with extra information for the lesson and the answers to the questions in the worksheet. Where possible, the lessons use concrete materials for demonstrations, activities or experiments. Where this is not possible,which is often, the lessons make use of data from real research (Fermilab, CERN etc.), computer simulations from Physics Education Technology (PhET) and thought experiments a la Einstein. Links to excellent web based resources like Physics 2000 and Fermilabyrinth are imbedded in the lessons.

Let me know if you find any of this useful. This will give me the energy to keep working on it. Especially, let me know of minor errors and major problems.This will help me improve the resources. I can be contacted with the email address that you would pronounce as "Roberta at Tevlin dot ca". Please, help protect me from spam and don't give this address to sketchy people.

So far, excellent help has been provided by; John Atherton, Tahira Nasreen, Dan Blanchard, Andrea Misner, Dave Doucette, Tim Langford, Sarah Torrie, Mark Ackersviller, Julie Lemay, Philip Freeman, Robert Prior, Rolly Meisel, Donald Messenger and Laure Ghia.
