Section 1: Vision

Using the image above, write a 5-7 sentence response describing why we see color.

OR Using the video to the

DO NOW

SWBAT label and describe the anatomy (structure) and physiology (function) of the Human Eye.

SWBAT discuss various aspects of visual acuity and their relevance in sports (citing specific examples)

Objective

Brainstorm with a partner, and generate of list, of specific examples where vision is vital to the success of athletes.

(EX. Catching a fly ball)

Our eyes normally react to anything that happens in our field of vision... spectators, other participants or even the wind blowing leaves on an overhanging branch. Visual Concentration is the ability to screen out these distractions and stay focused on the ball or the targe

Visual Concentration

When you are playing any sport with a ball or a fast moving opponent, it is important that you be able to follow objects without much head motion.

Eye Tracking

Eye-Hand-Body Coordination is how your hands, feet and body and other muscles respond to the information gathered through your eyes. It is an important part of most sports because it affects both timing and body control.

Eye-Hand-Body Coordination

Eye, Hand, Body Coordination

Athletes ability to process and remember a fast moving, complex picture of people and things. This is called visual memory. The athlete with good visual memory always seems to be in the right place at the right time.

Visual Memory

http://www.allaboutvision.com/sportsvision/skills.htm

Picture yourself hitting a perfect drive…long and right down the middle of the fairway. Believe it or not, picturing yourself doing it can actually help you do it. Visualization is the skill that enables you to see yourself performing well in your "mind's eye" while your eyes are seeing and concentrating on something else, usually the ball. Using scanning techniques, researchers have found that the same areas of the brain that light up during performance also do so when you visualize the performance.

Visualization

When a soccer player sees a teammate out of the corner of his or her eye, the player is using his peripheral vision. Because much of what happens in sports does not happen directly in front of you, it's important to increase your ability to see action to the side without having to turn your head.

Peripheral vision

The pitcher releases the ball and you swing…a little late and you hit a weak foul down the line…or worse you miss the ball completely. Or, maybe you just can't quite return that tennis serve. You need to improve your visual reaction time, or the speed with which your brain interprets and reacts to your opponent's action.

Visual Reaction Time

In racket sports, depth perception enables you to quickly and accurately judge the distance between yourself, the ball, your opponents, teammates, boundary lines and other objects. When you are shooting or hunting, if you consistently over or underestimate the distance to your target, poor depth perception may be at fault.

Depth Perception

DO NOW Day 2Watch the following clip. Explain which types of visual acuity Bill Buckner could have used to make this routine play and win the 1987 World Series for the Boston Red Sox.

Day 4

Using your Chromebook, visit the following website

http://kidshealth.org/kid/htbw/eyes.html#

Describe the function of the red terms using information your learned through reading the article

Time Permitting: Read other related articles and prepare some important points to share out with the class.

Station 1

Optic Nerve, Iris, Cornea, Pupil, Lens, Dilation, Macula, Retina, Refraction, Occipital lobe, Sclera, ciliary muscle

Follow the following protocol in order to label the anatomy of the eye.

- Color the retina RED- Color the iris, the same color as yours.- Color the optic nerve Green- Outline the sclera with Black- Color the lens Yellow.- Draw a star in the center of the pupil- Outline the Cornea Orange. - Outline the veins Blue.- Outline the arteries RED.- Draw a smiley face on the position of the Macula.

Station 2

Using your Chromebook and headphones, please watch the following videos, pausing when you see necessary, and take notes on the anatomy and physiology of the human eye.

Station 3

This activity will be worth your first QUIZ grade of the school year. (40 points)

You will be graded on creativity (use of various materials), anatomical (structural) accuracy, and completeness.Your assignment is to brainstorm, design, build, and display a model of a human eye using household materials. These materials must be strategically used to resemble the anatomical features of the eye.

Activity to Review Ocular Anatomy

Using a notebook provided by Mr. Pezzuto, your group must share responsibility to brainstorm and record collaborative ideas regarding building your model.

Each group member must be engaged in the conversations and must share their own ideas.

Be sure to list all group member names, a materials list, and at least two labeled drawings of your groups planned model.

Step one: Brainstorm/Plan your Design

Obtain Materials for building your Ocular model.

Be sure to bring enough materials to complete your model during the build period, including assembly materials (tape, glue etc.)

Do not bring in any items that could be dangerous or inappropriate for school.

Please no food, clay, or playdoh. (Be creative!!!)

Step 2: Homework

Students must hand in the following items to receive a 100%:

-A comprehensive notebook that demonstrates (names, a materials list, at least two drawn and labeled designs). (10 points)-An accurate anatomical model of the human eye including the following structures(Optic Nerve, Iris, Cornea, Pupil, Lens, Macula, Retina, Sclera, Veins, Arteries). (20 points)-A Completed worksheet from each team member including each structure colored accurately as well as each structures physiology described. (5 points)-The completed model uses an appropriate array (diversity) of materials to represent each part of eye anatomy. (5 points)
