As review for testing, 4th grade scientists have been extending their learning about how the brain controls everything they do through taking in stimuli! Yesterday, they performed a ruler drop to measure how long it took their brains to send the message to their arm to catch the ruler. Some of them were as quick as the blink of an eye, literally! Today, the stimulus is smell. They were challenged to find their “family” by only using their sense of smell, no talking allowed. Afterwards, they had a great discussion on how once they smelled the scent, what decisions the brain had to make to help them find their “family”. It’s been a fun day! #EESlegacy #GreenbrierProud
