    School trips are one of the things that school children hope for about school. They are one way to show children that they can also learn much outside the classroom.

A good side of having a school trip is that children can use the learned or the learning things in class in true life. Knowledge in science and maths can be used. Then students will remember their lessons well. Also, students will have first-hand information on how their school subjects work outside classroom. For example, a visit to a museum can not only learn about history but can also learn about science or geography.

    What's more, always learning in classroom may make some kids lose interest in a subject. This is really true for some difficult subjects. However, kids can learn in new environments during school trips and take on as much information as they want and can.

    School trips also help kids get to know each other in a more relaxed environment, without thinking about tests or grades.

    Showing students the larger world around them can really help them learn more.
