        SciGirls | Passion for Pixels

        Did you know when you look at a photo of a planet in space, you're really looking at a set of numbers? Remote-sensing satellites take pictures and gather data that is transmitted to the ground as digital signals, or sets of numbers. Then computer software converts the numbers into color images. Play with data transmission using this SciGirls activity to guide students through encoding messages into digital signals they send each other.
