Senses (Elba Lopez)
Principles illustrated:
Gathering data
Making observations
Communicate findings
Applicable Standards:
Physics (Waves)
4d. Students know sound is a longitudinal wave whose speed depends on the properties of the medium in which it propagates
Life Science
5g. Students know how to relate the structures of the eye and ear to their functions.
7c. Communicate the logical connection among hypotheses, science concepts, tests conducted, data collected, and conclusions drawn from the scientific evidence
Biology
9b. Students know how the nervous system mediates communication between different parts of the body and the body’s interactions with the environment.
9d. Students know the functions of the nervous system and the role of neurons in transmitting electrochemical impulses.
9e. Students know the roles of sensory neurons, interneurons, and motor neurons in sensation, thought, and response.
Questioning Script
Prior knowledge & experience:
the senses and their roles in communicating with the brain and the rest of the body.
Collecting quantitative and qualitative data
making observation
Root question:
Target response:
Wagon Wheel: The diagram appears to spin.
persistence of vision produces the illusion.
Hearing: it sounds like a bell. the metal in the utensil starts to vibrate when struck
these vibrations are transmitted up the string to the ears.
How do you feel?
the person feels only one point on the forearm and two points on the thumb tip.
Common Misconceptions:
there are more or less than five senses
if you lose a sense the others become heightened
