Imagine you want to send a postcard to your friend who lives far away. Here's how it travels in different ways:
- You Write the Postcard: First, you write a message and draw a picture on the postcard.
- Put on a Stamp: Then, you stick a stamp on the postcard. The stamp is like a ticket that helps the card travel.
- Mail It: You put the postcard in a mailbox or give it to a mailman.
- Travel by Truck: The mailman collects the postcard and takes it to a mail center in a big truck.
- Travel by Airplane: If your friend lives very far, the postcard may fly on an airplane to reach their city quickly.
- Travel by Truck Again: After the airplane lands, another truck takes the postcard to a local post office near your friend's home.
- Delivered by Mail Carrier: Finally, a mail carrier walks or drives your friend's street and delivers the postcard to their mailbox.
So, the postcard travels by walking, by truck, and even by airplane before reaching your friend's hands!
