I cannot believe it is almost December! Christmas is fast approaching. Use this great opportunity to take a break from traditional homeschool routines, or incorporate them in a Christmas homeschool science lesson. I love learning without a textbook, and these experiments and building activities are a great way to incorporate fun with learning.
