Students explore the brain’s role in receiving information from the senses, processing that information, and controlling the muscles to enable movement. In the activity, students test their reflexes and develop a mental model of how their brain works.
TRY THIS OUT! Look below for tips. Then go to the next slide.
Why did it look like there was a hole in your hand? Any ideas?
QUICK EXPERIMENT (PART 1 of 4)
Teacher: choose a volunteer to quickly read these words out loud to the class.
QUICK EXPERIMENT (PART 2 of 4)
Teacher: have the same volunteer say the COLOR of each word out loud. What do you notice?
QUICK EXPERIMENT (PART 3 of 4)
Now everyone try! Get into partners. Listen as your partner reads the words out loud. Then switch jobs.
QUICK EXPERIMENT (PART 4 of 4)
Now listen as your partner says the COLOR of each word. Make sure they get them all right! Then switch jobs.
Which task was harder--reading the words, or saying the colors?
Why do you think that one was so hard to do?
You've completed the Exploration & Activity!
Below are ideas for extending this topic beyond the activity & exploration which you just completed.
These Common-Core-aligned readings are free with registration on ReadWorks. All readings include comprehension questions.
Try the “Think Fast” activity again -- but instead of a ruler, use a dollar bill. Start with the catcher’s thumb and finger in the middle of the bill. Remind the catcher that they can’t move until they SEE the bill drop.
The typical human reaction time is about ¼ second. That’s long enough for the 6-inch bill to fall completely through the catcher's fingers!
These online simulations let you find out how quickly you can react in two very different situations.
