My Take
While some students may enjoy this app, it mixes juvenile poems with quite detailed information about the item being x-rayed. Advanced students may wish to skip the poems entirely and just read the text. Some of the items selected for x-raying are curious - there's not much to see on the inside of a piggy bank or an umbrella.
How I Use It
Advanced readers have used this for reading on their own. It was not an app that grabbed their attention or kept them coming back.
