AR Chemistry Screencast Atomic Mass vs. Atomic Number

This trigger image when scanned with LAYAR leads to a video/screencast in Explain Everything in which I ask the viewer to make a screencast + draw a Venn diagram and compare and contrast the difference between an atomic number & atomic mass. Students APP-smash in Educreations and eBackPack

  1. Hello,
    Fellow chemistry teacher here. I’m just learning about AR. I downloaded the Layar app and tried to scan the image above. The app is saying the image cannot be found. Does it need to be printed out for it to work? Does it not work with my ipad’s camera pointed on my computer screen? What else am i missing to get this to work?
