Paper and pen.
How To Play:
Divide the group up into teams. Provide each team with a copy of the list of things that must be collected. The first team to collect everything, or the team that has the most items collected at the end of the specified time frame is the winner.
“Make the boundaries clear for all. Items listed should not be collected by damaging anything. An example is listing birch bark as an item. Make it clear that the birch bark must already be on the ground or from a fallen tree. Award a few points for easy items and more points for those harder to find. A scavenger hunt is an ideal outdoor activity.”
