Google Expeditions is a free app that gives you access to hundreds of AR objects, all arranged in categories. The quickest way to use the app is to open it, select AR from the menu, and you'll see the list of categories, each having a few images to view. Select an image, point your phone or tablet at the location where you want the AR object to appear, and click. It take a few seconds to download the image, then it will appear. You can resize (bigger or smaller) the object and while you can't rotate by moving the object on the screen, you can walk around the object to see it from any point of view.
You can also create AR tours in your classroom by selecting the objects you want students to see, printing the AR markers and placing them around your room. When students scan the markers, they'll see the AR objects. Here's a link to a teacher-created youtube video that provides a quick and easy to follow demo showing how it's done:

It enables students to interact actively with each other. Through the experience of living a reality, students get to share their different opinions of the encounter. This helps them learn from one another by sharing their views.
