□ Read the Explorelearning Enrollment Handout in the Introduction materials folder tolearn how
you can access Gizmos.
□ Make sure you use a name your instructor can recognize when you log in and don’tforget to
do the 5 question quiz at the end of the Gizmo. They are part of your mark.

Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
1. What are different types of information that your body can detect from the outside world?
Different types of information that our body can detect are the six senses which are sight, hearing, smell, taste, touch and extrasensory Perception.
2. What organs does your body use to collect the information described in the last question?
The organs that our body uses to collect the information are eyes, ears, nose, tongue and skin.
Gizmo Warm-up
Stimuli are changes inside or outside the body that
cause a response. In the Senses Gizmo™, you will
explore how different sense organs detectstimuli from
the environment and send messages about that stimulus
to the brain.
On the NEURAL PATHWAYS tab, drag the apple slice into the white Stimulus box. Drag theeye into
the Sense organ box. Click Play ).
1. What do you observe? Light receptors at the back of the eye are activated by incoming light
, 2. How do you know that the eye senses the apple? We know this as we can see that the nerve cellstransmit
light signals to the brain.
3. The neural pathway represents the nerves that connect the sense organ to the brain. Whathappens
along the neural pathway when the eye sees the apple? The visual cortex in the
brain processes the signals to create the perception of vision.
Activity A: Get the Gizmo ready:

brain Reset ).
Introduction: The brain is organized into different regions that have different functions. Most sensory
information is processed in the cerebrum, the “wrinkly” area that forms the outer part ofthe brain. The
nerves that connect a sense organ to the part of the brain responsible for that sense is called the neural
pathway.
Question: What happens when stimuli are detected by sense organs?
1. Observe: Drag the apple into the Stimulus box and the tongue into the Sense organ box.Click
Play.
A. What does the tongue detect?The
taste
B. What happens along the neural pathway when the tongue detects the stimulus?
Taste receptor cells in the taste buds of the tongue react to molecules in food,
activating nerve cells.
Nerve cells transmit taste signals to the brain. The gustatory complex in thebrain
processes the signals to create perception of taste.
The glowing dot represents the transmission of a nerve impulse along the nerves that make
up the neural pathway. A nerve impulse is an electrical signal that travelsfrom one nerve cell to
another.
C. Which part of the brain processes this signal? Gustatory cortex
2. Compare: Click Reset. Select the speaker for the stimulus and the ear. Click Play.
A. What part of the brain detects the signal from the ear? Auditory cortex
B. What are similarities between this pathway and the pathway in question 1? Both the nerve cellstransmit
sound signals to the brain.
