📚 Topic Summary
Unplugged activities are all about learning computer science concepts without actually using a computer! This helps you focus on the logic and problem-solving aspects. A 'while loop' is like a set of instructions that keeps repeating as long as a certain condition is true. Think of it like brushing your teeth: you keep brushing 🦷 (looping) WHILE your teeth still feel dirty (the condition).
In data science, while loops are super useful for tasks like cleaning data (repeating the cleaning process until the data is 'clean'), running simulations (repeating the simulation until you get stable results), or training machine learning models (repeating the training until the model reaches a certain level of accuracy). This activity will help you grasp the fundamental logic behind these processes.

✍️ Part B: Fill in the Blanks
A _________ loop continues to execute as long as its _________ is true. Each time the code inside the loop runs, it's called an _________. If the condition never becomes false, the loop will run _________, creating an _________ loop. To avoid this, make sure the condition eventually becomes _________.
Word Bank: iteration, while, infinite, false, true, condition
Answers: while, condition, iteration, infinitely, infinite, false
🤔 Part C: Critical Thinking
Imagine you're sorting a pile of unsorted papers into alphabetical order. Explain how you could use the concept of a 'while loop' to describe this sorting process. Be specific about what the 'condition' would be that keeps the loop running.
