Why not use "Pokemon Go" to introduce your students to Augmented Reality?
This product includes a17 pdf pages to create the bulletin board. I have included two Pokemon Balls. The Poke Balls are not copyrighted so I could include them. You could include other Pikachu or other characters but they are not included with this product.
Check out Zdnet's article "10 industries using Augmented Reality and Virtual Reality." It gives specific examples of the industries listed on the bulletin board.
