SciStarter is challenging you to a special mission to join and participate (at least once) in any three SciStarter Affiliate projects. Complete your mission and you'll earn the SciStarter certificate. Keep on participating during Citizen Science Days and you'll be eligible to become one of the top three mission contributors to win some swag and be connected with of one the scientists you helped!
Your contributions may take up to a day or two to show up in your dashboard, but that won't prevent you from completing the mission.
