Schools are looking for passion. They want to know if your child can start something and persevere long enough to master it. Let your child know not to discuss video games or TV shows, but instead, to discuss something educational like reading, leading a school committee/newspaper, science experiments, etc. These are more impressive answers to give, but don't have your child feign these interests if they are not authentic. Other notable topics could be musical instruments, sports, building model planes, etc. Regardless of what they choose to talk about, your child must show passion in their answer.
