GIZMO SENSES -ALL ANSWERS CORRECT-GRADED A.

Document Content and Description Below

Student Exploration: Senses  Read the Explorelearning Enrollment Handout in the Introduction materials folder to learn how you can access Gizmos.  Make sure you use a name your instructor can recognize when you log in and don’t forget to do the 5 question quiz at the end of the Gizmo. They are part of your mark. Vocabulary: auditory cortex, auditory nerve, cerebrum, cone, gustatory cortex, hair cells, hypothalamus, involuntary, nerve impulse, neural pathway, neuron, olfactory cortex, olfactory bulb, optic nerve, rod, sensory neuron, somatosensory cortex, somatosensory nerves, spinal cord, stimulus, thalamus, visual cortex 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 detect stimuli 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 the eye into the Sense organ box. Click Play ). 1. What do you observe? Light receptors at the back of the eye are activated by incoming light2. How do you know that the eye senses the apple? We know this as we can see that the nerve cells transmit light signals to the brain. 3. The neural pathway represents the nerves that connect the sense organ to the brain. What happens 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: Senses and the brain Get the Gizmo ready:  On the NEURAL PATHWAYS tab, click 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 of the 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 ne
