This Outdoors Scavenger Hunt activity printable is a perfect Earth Day activity, Arbor Day activity, or for anytime of the year! Students can either mark things off as they find them, write down what they find, or take photos of the item! You may wish to staple this list to a bag big enough to collect all the items! I love to have students pick up trash as they go around the school campus on this nature scavenger hunt as well.
