An interesting post at Skepticblog addresses the validity of the “Burger Experiments” made popular on the internet over the past few years. In a nutshell….
…a McDonald’s hamburger and fries are left out for weeks or months. To the surprise of some, the food does not rot away to nothing but instead shrivels a little and becomes hard and shiny, but does not get moldy or rotten. The implication is that there is something wrong and unnatural about food that doesn’t rot when left out.
As the post points out, these types of content can function as useful fodder for teaching the basics of the scientific method. It would be interesting to design an exercise in which the students are instructed to watch / consume said content and then deconstruct them from a purely scientific point of view.
