Ugears STEM Lab Counter

Ugears STEM Lab Counter: The Counter model registers repetitive actions. It is an integral part of a device called an “Odometer”. The model has three-cylinder gears with numbers from 0 to 9 and a Geneva Drive. This combination allows you to see an interesting mechanical feature: when the reciprocating motion of the click-button using the Geneva Drive mechanism turns into the rotary motion of the cylinder gears with numbers. The Counter provides two options of data registering: a click-button on the roof of its body, and a turn handle on its side. Pressing the click-button or turning the handle makes the Counter shift in one place. When the count passes 9, the Geneva Drive catches the next register cylinder and adds it to the count. Altogether, the three-digit display of the Counter can register values from 1 to 999. You can open the front panel of the counter and reset it manually. Try counting steps on your way home. Or how many people you meet on a stroll through the park. How about, the number of blue cars passing by your house in one hour? Count stairs at home, at school or at a friend’s house.

Experiment: The model comes with a QR Code to download an interactive Pocket Model Study Guide which includes engaging and interesting tasks to learn more about how a Counter works.
