Charmreef, Where Crayon Fish Swim on the TV

Field notes

The activity begins on a phone, where the user creates an aquarium and prints its coloring page. After the child colors the sheet, the same phone photographs it before the aquarium is opened elsewhere. The page distinguishes a ten-character aquarium code from the shorter five-digit code used on an unfamiliar screen, including a television or grandparent's tablet. Optional sign-in is described as a way to preserve the aquarium list beyond the current browser.
