Okay kiddo, imagine you have a bunch of questions and you want to know how much you and your friends know about a certain topic, like dinosaurs. To find out, you would give your friends a survey filled with questions about dinosaurs. That way, you can find out what they know and what they don't know. This survey is called a knowledge survey. It helps you understand what people know or don't know about a topic. It's a great way to learn more about a subject and see how much other people understand too.
