Or at least “explain it like I am an 8th grader.” I am a middle school science teacher and am struggling with explaining these concepts in a simplified way that my students can understand. They have some prior knowledge about waves and how they travel. I appreciate any help you can provide!

Analog is a wheelchair ramp and digital is a staircase. An analog signal can smoothly vary around a given value, while a digital signal can only exist in discreete values. Digit means finger, so think of how you count on your fingers: one integer at a time.
In terms of data processing and transmission, digital data often has only two states- off and on, yes and no, true and false, 1 and 0, etc. This protects the signal from interference because the reciever knows it only has two possible inputs, at the cost of having to handle a longer signal.
