An Experiment about...Your Senses and Nervous System!
Think it
Sight, hearing, touch, smell and taste are what allow you to experience life and create memories of what you've encountered. These senses are part of a larger system, which includes the brain, spinal cord and nerves. The senses are responsible for receiving information from the world, but it's the brain that gives it all meaning.
Materials: - Open space for two people to stand, a 12 inch ruler, and a friend.
Try it:
Extend your arm with your thumb and index finger separated, as if to pinch something.
Ask your friend to hold the ruler vertically just above your hand. Your friend should drop the ruler between your fingers without warning.
Try to catch the ruler as fast as you can. How are your senses and nervous system working together to react?
Did you catch the ruler the first time or did it take several tries?
Did you get better with practice?
What do you think about the results of your experiment?
