Center of Gravity

III. Center of Gravity

1. Center of Mass of Males and Females
Materials: chairs, books, heavy objects
Procedures:
a. Place a chair next to the wall and stand a few feet from the chair. Without moving your feet, lean over and place your head on the wall and attempt to pick up the chair. No fair bending your knees. Is there a difference between males and females.

b. Try doing the same experiment with your back to the wall and the chair two feet in front of you. Good luck!

2. Your nose to the Floor (Men vs. Women)
Kneel down on the floor and lean down and put your elbow to your knee. Stick your arm and fingers straight out from your knee (keeping your elbow to your knee). Place a matchbook on its side right at the end of your fingertips. Now place your hands behind your back and tip over the matchbook with your nose.
