I found a variety of links to great math and science topics at http://www.askdrcallahan.com/links.html. 

Another helpful link for coming up with ideas for science or other subjects

 is www.keycurriculums.com/1355169.html.

I especially like the way they designed the dissection classes.  

One, more, or all can be taken with or without using any particular science 

curriculum.

Because we want to learn science and math in more non-traditional settings, 

I've been looking for all sorts of resources for "something different."

I hope to remember to blog about any great finds I run across.  

That way, I have sort of a running list of ideas to pull from at any given 

time during our homeschooling life.
