📚 Topic Summary
In AP Computer Science Principles (CSP), Scratch can be used to explore data concepts in a visual and interactive way. An unplugged activity allows you to understand the core concepts of data collection, analysis, and representation without using computers initially. This approach focuses on logical thinking and problem-solving by using real-world scenarios. Through engaging activities, you can grasp the fundamental principles of working with data sets, identifying patterns, and visualizing results – all crucial skills in computer science.
Imagine you're running a survey to find out which fruit is most popular among your classmates. An unplugged activity would involve collecting responses, tallying them up, and then representing the results using simple tools like colored blocks or paper charts. This tactile experience helps solidify your understanding before you start coding in Scratch.

✍️ Part B: Fill in the Blanks
Fill in the missing words in the paragraph below:
In a Scratch data project, we can use ______ to store information like names or scores. An ______ is a set of instructions that processes this data. We can then use ______ like bar graphs or pie charts to ______ the results, making it easier to understand.
🤔 Part C: Critical Thinking
Consider a scenario where you are collecting data about the weather each day for a month. How could you represent this data visually (without using a computer) to identify patterns or trends? Explain your method and why you chose it.
