My school-aged children are 14, 11, and 9. I have used an unschooling approach to science, while using SCM for all other subjects. I have used SCM Nature Study, and am finishing 106 Days of Creation Studies, God-willing, this year (I have 3 younger boys, including twins, so we’ll see). I plan to use a formal SCM science curriculum this year. Do any of the elementary science curricula cover the same material as 106 Days of Creation Studies? Many of the resources appear to be the same.
