Testing and Comparing Human Sensory Perception (Physiology)
kit #8
This kit provokes a personal interest as students identify response areas on their bodies. They become aware of their sensory perceptions and the physiological characteristics of the body receptors.
Scientific Concepts
• “Mapping” the taste sensations of sweet, salty, bitter and sour
• Determine olfactory fatigue and recovery times by inhaling different odors
• Discovers hot and cold nerve endings as they "map" a section of skin
• Locating nerve endings for touch (pressure) and pain
• Determining the two-point threshold of various parts of the body
• Investigating blind spots, dominant eye, visual accommodation, near point of vision and after image
• Experiments with flex actions
Accommodates one class with five groups of two students.
