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.
