I was looking around for notebooking topics and ideas yesterday and I uncovered a lot of interesting things on Squidoo. Here's the main search page. This is a cool page showing all different types of notebooking. Here's a page on anatomy. Here's one on chemistry. Here's a page on geography notebooking. Right now my kids are notebooking their way through all of the simple machines. This is going to take another week, probably and then we'll choose something else. Now I know where to look.
