What is your favorite curriculums and why??

I'm ordering curriculum....

I wanted to see what do you like to use for:

Science,
History,
Spelling,

and ....

Bible??

And why?

What do you like and (not like) about it?

I'm still looking for something I like better than what I've got in these subjects. I know I like workbook formats alot.... And I'm looking for something that is more student independant, and less teacher demanding. Fun, colorful, interesting, and effective is nice too, of course!:)

Thanks much~!! :)
