"Not every school has the resources necessary to take their students on an airplane . . . or spaceship. The iPad can bring the world to your students' fingertips in ways never before possible. Many national parks and museums have apps designed for onsite visitors. These navigational tools are also great for classrooms who can't make the trip. In fact, a variety of free apps can be used as virtual field trips so that children can travel the world from your classroom!"
