My girls are loving Science in public school this year, so I know I need to make more of an effort to do Science next year when we are homeschooling again. The problem is I don't know where to start! They will be in grades 4 and 2, and the next one will be starting Kindergarten. We tried Apologia Astronomy two years ago, but it just didn't really get done. I want something interesting, engaging, not too expensive, etc. I've looked a little bit at the God's Design For... series. I really don't know what else to look at. We believe in YEC, fwiw.
