This lab activity arouses a personal interest as students experiment to identify response areas of their body, and become aware of their sensory perception. Students map the taste sensation of sweet, salty, bitter, and sour, determine their olfactory fatigue and recovery times by inhaling different odors, actually discover that there are different nerve endings for hot and cold as they map a section of skin, locate nerve endings for touch (pressure) and pain, as well as determine the two-point threshold of various regions of their bodies, investigate the blind spots, dominant eye, visual accommodation, near point of vision, and afterimage, and experiment with reflex actions. Complete for 30 students.
