DKfindout! is an online resource for ages 7-11 featuring topics such as Science, Math, English, History, Geography, and the Human Body. It’s currently a work in progress with more info to be added, but looks to be fun age-appropriate starting place for learning about new topics. There are also quizzes, fun facts, and videos.
