Team Up

Story TimeGigi has got many ideas; she is determined to be an inventor. Gigi went to a hypermarket with her Mom, she saw her Mom put all the things they wanted to buy on the checkout counter, and all the things moved forward by themselves. She took a careful look at it and found out that there was a big belt that helped to convey the goods.

Story TimeThis is a similar idea to when the sushi train conveys food to its customers. Gigi looked online to figure out the secrets of the conveyer belt. A conveyor belt features two or more transport rollers mounted on one belt. The power is transmitted, via the belt, from one pulley to another.

Daily ApplicationA primary characteristic of a belt pulley is that two or more pulleys are inserted in one belt drive and the belt is the medium used to drive transmission of power from one pulley to the other. In factories or other things we see in daily life, belts are widely used. In addition to transmitting power, they are also used to convey goods. For example, the conveyer belt systems in airports.

Brainstorming

What other applications does a belt pulley have?

Hands-on Experiment

Place an object on the conveyor belt and let the belt move it forward. Try to deliver different things to see if it works,

what difference does it make to convey things that are very

heavy or very light.

Hands-on Creativity

Give it a try: make a conveyer belt that transports from a lower point, upward.

Let’s score yourself. How many stars do you get today?
