I think the world history fair in influences our life’s by we learn about different people and things. My guiding question was Leonidas life and how he died. What I learned from my research I that Leonidas had a half brother. The most interesting part was thank the world history fair. I found out that Leonidas father was Anaxandridas II. I learned from some 7th grade were that the roman made legion because of riots in their cities. The most interesting was kade's catapult .
