This lesson exposes students to the idea that computers have their own numeric language and that any data such as a picture, color, song, etc. can actually be represented using numeric values a computer understands.  Students will be able to identify the binary system and use the binary codes to represent textual data.  Students will also be able to represent pictures using numeric values by understanding and using the concept of pixels

Video Description:  Have you ever wondered where food comes from? Learn how Dr. Catherine Nakalembe uses NASA satellite data to show the health and location of crops around Our World.
