7 ) Develop and use models to show multiple solutions in which patterns are used to transfer information (e.g., using a grid of 1s and 0s representing black and white to send information about a picture, using drums to send coded information through sound waves, using Morse code to send a message).*

Visualize the relationship between the binary code of 1s and 0s and an image with this interactive tool. Students can investigate relationships by testing how a code is used to create an image pixel by pixel and how the quality of a picture (its resolution) can be improved. A student assignment includes a brief reading to provide context on the code and an opportunity to test out a code with a partner.

In this lesson, students recognize that codes and symbols are used in our everyday lives and realize how these codes assist in communication and living. By trying to break secret codes with classmates and communicating with each other using Morse Code, students can develop skills in finding patterns and using logic.
