This is the music portion of the latest AR app from Daqri called Enchantium . It features an AR trigger that you can print out. Once you scan this AR trigger each of the three musical cups emits unique sounds. You can compose different sounds by touching the iPad in various ways. This app is important for STEAM education K-12. You could use it to teach music to elementary students. However, I am going to use it in a high school physics lesson this week to allow students to investigate the principles of soundwaves. There are more features/AR triggers with this app that I will talk about in my next tutorial.
In the 21st century classroom: Students can see the shape of knowledge, Students can hear the shape of knowledge, students can TOUCH the shape of knowledge.
