Right Hand/Left Hand
First, let's check people for handedness...which hand do they prefer to use in the following tests? Mark your data sheet depending on whether they use their right or left hand. Observe your subject to see if he or she writes with the right or left hand. Just ask your subject to write his or her name. Which hand does your subject hold a pair of scissors when cutting a piece of paper? Ask your subject to cut a circle out of a piece of paper. Which hand does your subject use to throw a ball. Give a ball to your subject and ask him or her to throw it to you. Extra Tests (optional) Observe your subject to see if he or she eats with the right or left hand. You should only count the hand that is used to bring the food to your subjects mouth...which hand holds the fork or spoon? Observe which hand your subject uses to pick up a cup of water to drink. Materials needed: Pen or pencil and paper Paper and scissors Ball Cup with water (optional) Fork or spoon and food (optional) If you want to determine the STRENGTH of handedness, there are two different questionnaires you can use.

	Right Foot/Left Foot
Now, let's check people for footedness...which foot do they prefer to use in the following tests? Mark your data sheet depending on whether they use the right or left foot. Does your subject kick a ball with his or her right or left foot? Does your subject step up a stair leading with his or her right of left foot? Have your subject stand with both feet flat on the ground in front of a step. Ask your subject to step up the first stair. See which foot is lifted up. (Note: if you do not have any stairs, you can draw a line on the floor or put a piece of string on the ground. Ask you subject to step over the line or string. See which foot goes over the line.) Which foot does your subject use to step on things? Put a small object, such as a coin, on the floor. Ask your subject to step on the coin. Which foot does your subject use to step on the coin? Materials needed: Ball Stairs Coin

	Right Eye/Left Eye
Now, let's check people for eyedness...which eye do they prefer to use in the following tests? Mark your data sheet depending on whether they use the right or left eye. Which eye is used by your subject to look through a tube? Give your subject an empty paper towel tube (or just roll up a piece of paper). Which eye does your subject put up to the tube? Which eye does your subject "sight" with? Ask your subject to look at a distant object across the room (such as a clock on the wall). Tell your subject to quickly line up one finger with the distant object so that this finger is blocking the object. Now ask your subject to close one eye, then the other. When your subject closes one eye, the object will remain blocked. However, with the other eye, your subject's finger will "jump" out of the way. Mark your data sheet with the eye that still blocked the object. For example, if the object remained blocked when the right eye was used, mark right eye. Another sight test. Cut a small circle out of the middle of a piece of notebook paper. The circle should be the size of a small coin. Give the paper with the hole to your subject. Ask your subject to use both eyes and to look through the hole in the paper at a distant object (like a clock on the wall). Ask your subject to bring the paper closer and closer to his or her face while still looking at the distant object. Which eye does the hole in the paper finally reach? The right or left eye? Materials needed: Paper or cardboard tube Paper with small hole

	Right Ear/Left Ear
Now, let's check people for earedness...which ear do they prefer to use in the following tests? Mark your data sheet depending on whether they use the right or left ear. Which ear do your subjects use to listen to a whisper? Tell your subjects that you are going to whisper something very quietly and that you want them to "cup one ear" to make the sound louder. Speak quietly and see which ear do they decide to use. Which ear do your subjects use to listen to a sound from a box. Get a small box and ask your subjects to identify what is inside the box by putting an ear up to the box. Which ear do they use? Which ear do your subjects use to listen through a wall. Ask your subjects to try to listen through a wall. Which ear do they use? Materials needed: Small box

Collect and Analyze Your Results For each subject, determine if all of the responses were on the right side, left side or mixed. For example, did your subject use his or her right hand for all the handedness tests? If there are more right sided responses than left sided responses, you can call that person right handed. Do the same for the foot, ear and eye. Is your subject right or left handed? Right or left footed? Right or left eyed? Right or left eared? Summarize the data from all of your subjects. How many people in your test were right handed, how many were left handed? How many people in your test were right footed, how many were left footed? How many people in your test were right eyed, how many were left eyed? How many people in your test were right eared, how many were left eared? Does whether your subject was a boy or girl make a difference? How many boys were right handed? How many girls? Compare your data to this table with these numbers from another experiment (reference below). Were your numbers different? % of Men and Women who Use the RIGHT SIDE Men Women Hand 86 90 Foot 77 86 Ear 55 65 Eye 73 69 Table Reference: Stanley Coren, The Left-Hander Syndrome: The Causes and Consequences of Left-Handedness, Free Press, New York, 1992, p. 32
