This unit is on the nervous system, the brain, and how sensory receptors receive information and convert it to an electrochemical signal that is sent through the nervous system to the brain. Once the signal gets to the brain it is processed and the brain may send a signal to tell the body how to respond or store the information as memory. This unit begins and ends with the use of phenomena.

NGSS MS-LS1-8 Gather and synthesize information that sensory receptors respond to stimuli by sending messages to the brain for immediate behavior or storage as memories. [Assessment Boundary: Assessment does not include mechanisms for the transmission of this information.]
Each sense receptor responds to different inputs (electromagnetic, mechanical, chemical), transmitting them as signals that travel along nerve cells to the brain. The signals are then processed in the brain, resulting in immediate behaviors or memories. (MS-LS1-8)
