Interactive PowerPoints are terrific tools for self quizzing before an exam. This particular presentation is about the action and physical features of rivers. There are nine boxes to click on, each leading to a picture or map. When you click on the image, the answer appears! Because it requires experience with topographic maps, it would be most suited to high schoolers. Also, the maps and one question has to do with Scotland's rivers. You may want to replace those with questions about local rivers for relatability.
