Who says you can't teach science the week before Christmas break. Miss Hypothesis has found a way in her post, Exploring the Science of Santa's Season. I just purchased her teachers pay teachers unit for I-Can-Be-a-Scientist-Exploring-Santas-Favorite-Season. It is fantastic...loaded with 138 pages of math and science. Some of the topics covered are living and nonliving, magnets, and path of movement. It is definitely worth the $8.00.
