Are you teaching a center of gravity unit and looking for a way to explain the difference between a high COG and a low COG? Look no further. Have students scan this AR trigger with the APP LAYAR. It takes them to a Tellagami on my You Tube channel in which I ask them to find a photo of a dog with a low center of gravity and a photo of a cog with a high center of gravity. I used this in my high school physics class and it was a big hit. Perhaps you can use it in your own learning environment.
