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.
