Alien and Duck Tin Can Telephone Coloring Page

Tin can telephones work because vibrations from your voice travel through the bottom of the can and across a tight string to the other side.

World Hello Day was created in 1973 to highlight how open communication can build global friendship and peace.

A duck's quack actually does echo, despite a popular urban myth claiming that it does not.

Build a working string telephone using paper cups and yarn to demonstrate how sound waves travel through solids.

Practice saying hello in three different languages to celebrate the theme of communication.

Discuss the importance of listening as well as speaking when sharing a conversation with friends.

Color the duck in bright yellow with an orange bill, or try brown and green like a real mallard.

Pick imaginative shades like lime green, bright purple, or sky blue for the friendly alien.

Use a fine-tip pen or marker to draw sound waves around the telephone cans.

Add a custom background, such as grass below the duck and starry outer space behind the alien.

Cut out the finished characters and glue speech bubbles above them to write friendly notes to classmates.

Use the sheet as an introductory coloring activity for a science lesson on sound and acoustic vibrations.

Turn the completed artwork into a homemade greeting card for World Hello Day on November 21.
