Mr. Marks is Quantum High's award-winning science teacher and an all-around nice guy. If you need help with science, or just about anything else in your life, Mr. Marks is your man. Mr. Marks has invented some amazing gadgets, but keeps many of them locked away until he can figure out what to do with them. He loves science and can always find a way to make his lessons more exciting if kids start to drift off in class. Mr. Marks believes that we can solve most of our problems through science if we'd only take the time to dig down deep into the subatomic world. But does Mr. Marks know about his students' explorations into the subatomic universe? Does he know that they turn into quarks and then return to his classroom with a new understanding about the science subjects he's been teaching them? And, what does Mr. Marks know about the mystery machine the kids find in Quantum High's basement? Find out as Quarked! Adventures in the Subatomic Universe unfolds.
