77 free trivia questions for 10 year olds with answers, pitched at the age where kids know a lot more than grown-ups expect but still love being surprised. There is a space round (the hottest planet, the smallest planet, what happened to Pluto), animals (the smallest bird, what a shark's skeleton is made of, why a dolphin is not a fish), world geography (capitals of Japan, Australia and Canada, the smallest country, the biggest reef), history (the Titanic, Machu Picchu, Anne Frank, the first hot air balloon), science (volcanoes, earthquakes, dinosaurs, Darwin and Newton) and a little art and music. The rest is the stuff 8 to 11 year olds actually talk about: Minecraft, Roblox, Fortnite, Among Us, Pokémon, Lego, Zelda, Frozen, Encanto, Toy Story, SpongeBob, Percy Jackson, Harry Potter and Taylor Swift, plus a sports round on basketball, hockey, golf, Wimbledon and the Olympics. Difficulty is mixed, so younger kids will get the easy ones and an 11 year old will still have to think. Every question is multiple choice with four answers and a one-line explanation that adds an extra fact. It works on a phone, read aloud in the car, or as a family quiz night. Every answer was checked against a reference page and shows its source once you have answered.
