Multiple Choice Questions on Scratch Loops for Grade 8

📚 Quick Study Guide

• ♾️ The forever loop runs the code inside it indefinitely. It never stops unless you manually stop the program.
• 🔢 The repeat loop runs the code a specific number of times. You define how many times it repeats.
• ⏱️ The repeat until loop runs the code until a certain condition is met. The condition is checked before each repetition.
• 🚦 Loops are essential for creating animations, games, and interactive stories in Scratch.
• 💡 Nesting loops (putting one loop inside another) allows for complex patterns and actions.
• ✍️ Be careful with forever loops! If not managed well, they can cause your Scratch project to freeze.
