Science plan for next year

Here is my science plan for my kids for next year. Adjusting the requirements by age. I have Katie 2nd/3rd & James 5th

I'm going to get Apologia's text book: "Swimming Creatures of the Fifth Day"
the book is $35 at http://www.adoremusbooks.com/index.asp?PageAction=VIEWPROD&ProdID=3704
They are having a 20% sale using discount code CHINO67 until 7/16. and free shipping on over $25.
LOOK at a sample module on whales here at the Apologia Website: http://apologia.securesites.net/pdfs/sample/ecz2_2.pdf

Then do notebooking (which is lapbooking in a notebook since there will be lots of pages for a whole year or how long it takes.)
using Live N Learn's materials. They are still working on it, and should be done in a week or 2. I think this is going to cost $30

They have samples up at: http://www.liveandlearnpress.com/zoo2.pdf
which go with the whale sample that Apologia has up above.

I'm interested in putting together a co-op for science if other families want to do the same book.
