Here are my own observations of how the experiment proceeded. Son gathers kibbles in a small bag. Dog expresses immediate interest, racing over to regard boy with frantic expression. Son scolds dog for drooling before the experiment is even started. Sister shrieks that dog slobber is gross.
Mother evicts scientist and dog from kitchen.
Son complains that nobody cares about his science project, but he's wrong - the dog obviously does care, with a passion bordering on obsessive. The experiment is reassembled in the living room. In a demonstration of human Pavlovian response, my son reacts to the proximity of the television by picking up the remote and surfing channels. The dog whines, eager to begin work on the project. The TV is turned off.
