Using a simple circuit with the battery representing the brain, future physiologists test to see which solutions conduct electrical "nerve impulses." Enlighten learners with plentiful information on electric signals in the nervous system and the extensions suggested in the teacher's guide. Implement this and other lessons from the same unit when addressing Next Generation Science Standards for your middle school life science class.
