Today's Gratitude Item: Cute bunnies! Especially the cute bunnies that we get to use with our 10th graders. The kids really love this section of work and bunnies are a great learning / motivational tool. Our students learn how to care for rabbits and we chart the growth of our bunnies for about four weeks. For most, this is the highlight of our "Science Year".
