How can friends and family hear us on phone calls and receive the pictures and text messages we send? The key is in patterns of information transmission! Come along as we explore how information transmission works. See you in the video, mighty scientist!
Learn that calls, text messages, photos being sent are sent as a code from one phone to another
Understand that a digital signal can be defined as a voice converted or changed into a series of 1s and 0s which is called a binary code
Understand that a sound wave, text message, or photo is converted to a digital signal at the originating phone, transmitted to cell towers, and converted back once it is at its receiving phone
Learn that photos are composed of pixels
Understand how a CD is coded so we hear music when it is played in a CD player
