๐ Topic Summary
Imagine your computer's memory like a bunch of light switches. Each switch can be either on (representing a '1') or off (representing a '0'). This is called a bit. Computers use these bits to store all kinds of information, from text and pictures to instructions for running programs. When a computer 'remembers' something, it's simply keeping those switches in a certain pattern. When it 'forgets,' those switches get flipped, changing the pattern. This activity helps us understand how this works without using a real computer!
Unplugged activities are a great way to learn about Computer Science without using a computer! Through games, worksheets, and hands-on activities, you can learn the fundamentals of computational thinking.

๐ Part B: Fill in the Blanks
Complete the following paragraph using the words provided: bits, pattern, electricity, information, forgets.
A computer stores __________ by using __________ to represent either a 1 or a 0. When a computer remembers, it maintains a specific __________. If the flow of __________ is disrupted, the computer __________, losing the stored data.
(Answers: information, bits, pattern, electricity, forgets)
๐ค Part C: Critical Thinking
Imagine you have a row of ten light switches. Each switch represents a bit. How many different combinations of on/off patterns can you create? Explain how this relates to the amount of information a computer can store.
