This is something I came up with today after receiving some books today from my Aunt. I realized that instead of spending money on a science program for 2008, why not just use the new books I had received. I am using it with my dd's ages 4 and 6. We'll do notebooking along with it. Some weeks we'll do two days of science and some weeks 1.
I just copied and pasted it from word so the notes are to myself of things I'd like to do for a given week.

Books:
From the Cat in the hat learning library

1. Inside Your Outside
2. Clam I am
3. Wish for a fish
4. Whale of a Tale
5. Oh Say Can you say what's the weather today
