A field trip or excursion is a journey by a group of people to a place away from their normal environment. When done for students, it is also known as school trip in the UK, New Zealand; and school tour in the Philippines. In Western culture people first come across this method during school years when classes are taken on school trips to visit a geological or geographical feature of the landscape, for example. Much of the early research into the natural sciences was of this form. Charles Darwin is an important example of someone who has contributed to science through the use of field trips.
