Granted, this kid seems creative & entrepreneurial – the next generation of Maker; but why is building a marshmallow cannon science? I can think of a number of ways building and testing a marshmallow cannon could illustrate the scientific method. Successfully constructing a marshmallow cannon, however, is an engineering challenge – very suitable for a Maker Faire, but why is this a top Science Fair project?
In fairness to the marshmallow cannon, descriptions of the award-winning projects all sound like engineering or invention projects rather than exercises in the scientific method. I like gadgets and inventions, but is it small wonder that we are a scientifically illiterate society when even our Science Fairs don’t know what science is?
