Smartie or M&Ms (or a small non-food object) Straight-back chairs (student chairs work well) List the conditions required for an object to be stable. Identify ways in which balance affects our daily lives. Older girls will keep a lower centre of gravity, which is naturally located in the pelvis. Older boys tend to have bigger, heavier shoulders and a higher centre of gravity. As they grow, the centre of gravity shifts as their bodies change, depending on their sex. To keep your centre of gravity over your other foot, you lean your upper body or arms in the opposite direction to the leg.Īt the elementary school age, most students have a centre of gravity below their belly button.

You maintain your balance by keeping your centre of gravity over your support base (your feet).
