Multiple Choice Questions on Scratch Basic Blocks for AP Computer Science Principles

📚 Quick Study Guide

• ✨ Motion: Blocks that control sprite movement (e.g., move, turn, go to x: y:).
• 🎨 Looks: Blocks that change a sprite's appearance (e.g., say, think, switch costume).
• 🔊 Sound: Blocks that control audio playback (e.g., play sound, change volume).
• 🖋️ Pen: Blocks that allow sprites to draw on the stage (e.g., pen down, change pen color).
• 🎮 Control: Blocks that manage script execution (e.g., wait, repeat, if/else).
• sensing: Blocks that detect conditions (e.g., touching, distance, key pressed).
• ➕ Operators: Blocks that perform mathematical and logical operations (e.g., +, -, *, /, and, or, not).
• 📦 Variables: Blocks that store and manipulate data (e.g., set variable, change variable).
• 💬 My Blocks: Custom blocks to create reusable code snippets.
