Description:
In four activities and a "de-briefing" over a one-week period, students create digital images from binary data sets, and design information transfer systems. They use a digital camera to put pictures on a computer; observe magnified digital images; use graph paper to create digital information; create an information transfer protocol; design encrypted messages or pictures; as a team, decode a satellite image from space; and discuss ways to improve digital image resolution and accelerate information exchange.

Scientific background sections, student worksheets, and assessment rubrics are provided.
