Question

Are you left or right sided? Do you use the left or right side of your brain more?

Background Information

There are two sides of the brainEach person’s brain is patterned

differentlyOne side is usually more active than the

otherDifferent places in your brain are more

important for certain things

Hypothesis

If the person participants are from the same family then we think that they will have a lot of the same data

Materials

PaperPen or pencilScissorsBallStairsA coinPaper towel tubeSea shellVolunteers—at least 10Lab Notebook

Procedure

Make sure that each volunteer has time to do all of the tests and that you have all of the test materials ready.

On chart 1 do test 1 for hand dominance and write which hand they use.

Then do all of the other tests for hand dominance.

Test 2 is foot dominance, write which foot they use in each test.

Procedure 2

Test 3 is eye dominance. Record which eye they use.

Test 4 is ear dominance. Record which ear they use.

Make Table 2 for each volunteer. Write left or right for the majority of which hand they use most. Do this for hand, foot, eye, and ear dominance.

Calculate the percentage of people who are right and left handed, eye, foot, and ear dominant.

Procedure 3

Now look at the data.Are there more volunteers who are right

or left dominant with their hands, feet, eyes, or ears?

Now make a bar graph with two bars, one for left side and one for right side. Write the percentage under it.

Variables

One variable is find other ways to test if they are left or right sided.

Choose volunteers from different families because sidedness can run in the family.

When you collect data you can see if sidedness in linked to age or gender.
