We highly encourage participants to develop their own sustainability action plans (Going Green) / their election predictions (U.S. Election) and take part in the student competition, but this is not a mandatory requirement. Although such a participation will offer a great motivational incentive to your students, we understand that sometimes time pressure and other constraints can stand in the way of such an approach. So, the message here is: You are very welcome to participate in the project, even if you cannot submit a contribution to the competition.
