On this site, users submit “wonders,” questions about things they are wondering about. Once a wonder has been submitted, other users vote on the ones they find most interesting. Those with the highest votes are then selected by the site as Wonders of the Day, questions that have been formally answered by the Wonderopolis staff, along with added photos, videos, a vocabulary list, and even a short quiz to test your understanding.
Wonderopolis is fun to explore and would make a great option for free time, sub days, or to explore possible genius hour projects. Each article can be printed, saved as a PDF, or just read on the site.
To learn about ways to use Wonderopolis in class, check out Wonder Ground, an online network of teachers who use the tool.
