I made this insertion activity hoping that the light would not be too bright but bright enough to be fun and attract attention to the box opening during a simple insertion task.
The nurses approved!! Hooray !!
The top photo shows how I covered a box with sticky back felt and used velcro to attach to the light box.
The other photos show a white box that still needs to be covered with felt to create some color contrast. But you can see the inside light is covered with some translucent stickers. I cut openings on the bottom and top of the box so that the light shows through.
The man in the video is legally blind but he turns his head toward light so I think that this adaptation helps him to find the box opening.
