Digital and Analog Signals Mini Unit Resources
Students first become familiar with the terms digital and analog and connect many real life examples to both types of technology. They make and use a string telephone to experience the benefits (and disadvantages!) of analog technology and then compare and contrast digital and analog photos. Finally, students model analog and digital wave transmission with a drawing activity and provide evidence for the claim that digital signals are more reliable.
