It is finding out about what you do not know.
Science is discovery.
For instance, scientists once thought the world was flat, and the earth was the center of the universe, and so on. Answers that scientists once thought were correct are no longer even considered. By using more powerful tools, scientists are always learning more about our world and how it works. Doing science means having new ideas of how things work based on what we already know. Sometimes, the wrong answers are more important than the right ones.
