Think about the programmers who wrote the code for the PHeT simulation you used to learn about circuits. There is a picture below in case you need a reminder.
Try to write a set of steps that a computer might follow to build this circuit and get it to light. Make sure your set of steps also instructs the computer how to behave with a switch in the circuit.
As a bonus, think about any words you have heard that are related to logic or computer programming, and try to work those in. Look back at your list of scratch commands and use these!
Hint: Pretend the electrons are "sprites" (like the cat)!
