In most places, you need to be very, very sure that research subjects understand what they are agreeing to. Passively reading something usually isn’t enough. The minimum often some kind of interactive explanation that includes a way for subjects to ask questions. I’ve heard tell of groups giving short “quizzes” for experiments with wired requirements and side effects. For kids specifically, you often need to get both the parents’ consent and the child’s assent. The details vary with the child’s age (older kids opinions get more weight) and the nature of the research (kids can opt out of basic research, but the parents might be able to override the kids’s desire to (say) avoid a shot if it’s part of a potentially lifesaving clinical trial).
