ENGINEERING LAB · LESSON 02: BALANCING ACT
Balancing Act
He's holding the tray. You're stacking the stuff. How high can it go before he loses it? How balance works →
Goal Stack the tallest pile you can. Each turn, pick 1 of 3 wacky items and drop it on the stack. Anything that falls = CRASH.
Science The green dot is the stack's center of mass. Keep it over the tray. Heavy and lopsided items move it; tall stacks make him wobble more.
Press Start. Then pick an item, aim with the mouse, and click to drop it.
Aim with the mouse or the arrow keys. Turn with Q / E or the mouse wheel. Click or press space to drop.
BALANCING ACT · LEADERBOARD
One spot per kid (their tallest stack), by grade group. Everyone gets the same items in the same order, so it's fair. Click watch it to replay anyone's stack.
