History/geography and/or science resources for K

We're finishing up our K math curriculum and I'd like to do some history/geography and science for fun over the summer as time allows. Nothing crazy rigorous, just an excuse to look together at some things we didn't get to over the school year, take a break from math, and study things I know he'll find interesting!

Does anyone have any recommendations of books they've liked for this age?

I have "What Your Kindergartener Needs to Know" which has a great list of things for these subjects, but I'm also seeing if there's anything else out there.
