How Big Is…?

Plants and animals come in all different shapes and sizes. Some are very large, and some are very small. Turn your next hike into a photo scavenger hunt. In your team, take photos to match the items on your list. Try to find a plant that is smaller than your fingernail, as tall as your knee or over your head! What other scavenger hunt items can you come up with?
