3
ADD TO CHART: NERVOUS SYSTEM PARTS: Brain, spinal cord, nerves FUNCTIONS: 1. Sends quick messages between the brain and body parts 2. Controls our senses
4
MAIN NERVES OF THE BODY
5
VOCABULARY back of resource sheet NEURON - nerve cell SYNAPSE - a small space between neurons. A chemical goes across here to keep the message being sent
6
SOMATIC – nerves that control voluntary actions (moving skeletal muscles) AUTONOMIC - nerves that control involuntary actions (heart beat, breathing…)
7
SPINAL CORD - a group of long nerves that carry messages between the body and the brain VERTEBRAE -bones that protect the spinal cord
8
DID YOU KNOW? Different areas of your brain control DIFFERENT PARTS of the body
10
Funny bone is not a bone! It’s a nerve

What's Happening: in the retina of your eyes, there are 3 types of color receptors (cones) that are most sensitive to either red, blue or green. When you stare at a particular color for too long, these receptors get "tired" or "fatigued.". After looking at the flag with the strange colors, your receptors that are tired do not work as well. Therefore, the information from all of the different color receptors is not in balance. Therefore, you see different color "afterimages"...in this case I have used the "mirror" colors so you see the proper colors in the afterimage. You can also see that your vision quickly returns to normal since the afterimage does not last for more than about 5 seconds.retinaeyes

YOU ARE GOING TO TEST WHY YOU NEED TWO EYES

Two eyes are better than one, especially when it comes to depth perception. Depth perception is the ability to judge objects that are nearer or farther than others. To demonstrate the difference of using one vs. two eye to judge depth hold the ends a pencil, one in each hand. Hold them either vertically or horizontally facing each other at arms-length from your body. With one eye closed, try to touch the end of the pencils together. Now try with two eyes: it should be much easier. This is because each eye looks at the image from a different angle. This experiment can also be done with your fingers, but pencils make the effect a bit more dramatic.

o the one on the right. The actual dimensions of the circles are not too important and you don't have to color the circles. Place the target on the ground about five feet in front of you. Have a friend stand near the target. Have your friend hold out an ink marker with the tip pointing down. Close one eye. Tell your friend to move forward or backward or side to side until you think the marker would hit the center of the target if it was dropped. Tell your friend to drop the marker when you think the marker is over the target center. The marker should leave a spot where it hit the target. Try it 10 times with one eye closed and add up the "score" for the 10 drops. Now try it with both eyes opened (get a different color marker when you use 2 eyes to see the difference on the target). Is your score better when you use two eyes? Materials: Paper for target Markers (two colors)
