Meanwhile, bring 3 tablespoons water, the sugar and ginger to a simmer in a small saucepan over medium heat; cook, stirring, until the sugar dissolves, about 2 minutes. Remove from the heat and let cool; discard the ginger. Stir the ginger syrup into the tea. Pour into ice cube trays and freeze until solid, 2 to 4 hours. Freeze the chopped melon until solid, at least 2 hours.
