c. Next test eye dominance by doing these three tests:
1. Give your volunteer a paper towel tube or a toilet paper tube and ask them to look at a distant object through it. Observe which eye they use to look through the tube and record the result in your data table.
2. Give your volunteer the piece of paper you made a hole in and ask them to look through it. Observe which eye they use and record the result.
3. Hold your finger so that it is centered in front of your volunteer and ask them to close one eye to focus on the finger. Observe which eye they keep open and record the result.
d. Lastly test ear dominance by doing these three tests:
1. Stand front and center looking straight at your volunteer, tell your volunteer that you will whisper something in their ear, and ask them to cup their ear. Observe which ear they cup and record the result in your data table.
2. Give your volunteer a sea shell and ask them to listen to it. Observe which ear they put the shell to and record the result.
3. Have your volunteer stand facing a wall and then ask them to listen through the wall. Observe which ear they put to the wall and record the result.
5. After you have given your tests to at least ten volunteers, summarize all of your data together so that you can analyze your results. To do this, make a data table like Table 2 below in your lab notebook and summarize your data in it.
a. For each volunteer, write "Right" if they used their right hand for two or three of those three dominance tests
b. For each volunteer, write "Left" if they used their left hand for two or three of those dominance tests.
