Earthstones
In return for solving each challenge, teams are awarded an Earthstone, a small rock (or piece of paper) with a word on it. Each team is trying to collect all of its Earthstones by the end of the challenges. Since each team is carrying half of their own Earthstones and half of the stones needed by another team, each group’s success is dependent on the success of another group. During the final part of the challenges, each group constructs a meaningful sentence from their six Earthstones. If their sentences match all of your sentences, they will have successfully completed the Challenge Trail.
Prepare the Earthstones before starting the Challenges. Create the Earthstones either on paper or small rocks. Each set of four sentences should be composed of 6 Earthstones and marked in a way that distinguishes them as a set. Divide each set in half, mix them with another group and put in a bag with clear group identification markings.
