In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site. The activity can be done with same age or mixed age groups in almost any outdoor setting— along a trail, around a school or science center, at a camp, or on a family outing. By using their senses of sight and touch, and possibly other senses (depending on the challenges presented), learners become more aware of diversity in nature.
