Primary school students reading science fiction books could stimulate their curiosity and imagination and cultivate their interest in science and the unknown world. However, they should also pay attention to controlling the time and content of their reading so that it would not affect their studies and other daily activities. Science fiction books might involve some complex concepts and perspectives that primary school students needed to have a certain level of understanding and thinking ability to digest and understand. Parents and teachers can guide and monitor students to ensure that they can enjoy reading in a safe environment.
