In an effort to encourage kids to be kind to nature and get outside your kids can join the Dinosaur Train Nature Trackers Club for FREE!! Every month there are new challenges, activities, and free printables! For December the activities are Camouflage Cloak, Collect a Critter, Treasure Hunt, and Nature Collection. Plus you print a Life Cycles activity sheet, Nature Collections activity sheet, and a Night Sky Observation sheet too! You can even print a special secret club sign too!!
