ExplainerTools is a home for interactive explainers: ideas you can see, questions you can test, and little discoveries you can share. Start with a topic, find a thoughtful creator, and follow the question that caught your attention.
Interactive explainers to teach your kids anything
That is the spirit of ExplainerTools: make room for the next “why?” Whether you are exploring a camera, a river, a probability puzzle, or the Moon, there is something powerful about sitting together and changing one thing to see what happens.
We collect work from independent creators and link to their original experiences. Our family guides add clear explanations, sources, and small experiments to help parents begin a conversation. You can browse by subject, discover a creator's work, and save ideas to revisit.
Built around curiosity
Good learning resources make their assumptions visible. Our original diagrams identify what they simplify, and our articles distinguish research findings from practical suggestions. We credit the people who make the original experiences and encourage you to explore their work in full.
Begin with one question. Make a prediction. Try it together. Then see where the next question leads.
