This is a set of procedure and directions for conducting an experiment in "Change Blindness" with your students. Materials are not included in this sale. Materials are not difficult to acquire.
I have conducted this experiment for several years. Video links to my experiment and the one I modeled it after are included.
It is lots of fun and you can get several students in the class involved.
You need 2 days. A day of prep and a day to conduct the experiment.
