A while back, I posted about The King Philip's War Adventure Freebie from Susan Kilbride. Ms. Kilbride has also written a number of other history and science unit studies. The kids and I are getting ready to start on one called "Atoms & Molecules," a free excerpt from her book Science Unit Studies for Homeschoolers and Teachers. It is geared for ages 4-13.
You can download the "Atoms & Molecules" Freebie, as well as several other science and history unit study freebies from Susan Kilbride, here:
