Students conduct an experiment to determine whether or not the sense of smell is important to being able to recognize foods by taste. They do this by attempting to identify several different foods that have similar textures. For some of the attempts, the students hold their noses and close their eyes, while for others they only close their eyes. After they have conducted the experiment, they create a bar graph showing the number of correct and incorrect identifications for the two different experimental conditions tested.
