📚 Topic Summary
Unplugged activities are a great way to learn about computer science concepts without actually using a computer! Pretending to turn devices on and off teaches us about binary code and how computers use electricity. When a device is 'on', it represents a '1', and when it's 'off', it represents a '0'. This simple system is the foundation for everything a computer does, from showing videos to sending emails. By understanding how devices are turned on and off, we get a basic understanding of digital logic and how these devices function at their core.

✍️ Part B: Fill in the Blanks
Complete the paragraph using the words: electricity, on, off, computer, switch.
A ________ uses ________ to perform tasks. A simple way to control a device is with a ________. When the switch is ________, the device is working. When it's ________, the device stops. This concept is foundational to how a ________ functions.
🤔 Part C: Critical Thinking
If you could invent a new 'unplugged' activity to teach computer science concepts, what would it be and why?
