here is what I did, pich an article (or jsut start with a wiki article)
take out all the facts and put them in a list under each section / chapter / "part" heading - as in single / few word facts.
cross reference each fact with google, to check its a common fact, and pick up additional information along the way.
jumble the facts up a bit and then turn it onto paragraph (obviously making sure that the facts stay in the right groups)
eg one I had to do because our son forgot until the night before it had to be in
my original infor from
http://en.wikipedia.org/wiki/Prairie_dog
my notes started
Prairie dogs (genus Cynomys)
burrowing rodents
native of North America
like grasslands
five species
black-tailed, white-tailed, Gunnison's, Utah and Mexican prairie dogs.
ground squirrel
United States, Canada and Mexico
I then google each "fact" and make sure its looks correct and add additional information
I got an B+ for the article I asked my son to add 4 pictures to the essay he did not bother, they marked it down because there were no pictures.... (I also got good results from several other essays I did on the same way)
