Beginner
2. Who developed Scratch?
Scratch was developed by the Lifelong Kindergarten Group at MIT Media Lab.
Beginner
3. What is a Sprite?
A Sprite is a character or object that performs actions in a Scratch project.
Beginner
4. What is the Stage in Scratch?
The Stage is the background area where sprites perform actions.
Beginner
5. What are Blocks in Scratch?
Blocks are visual programming pieces that snap together to create scripts.
Beginner
6. What is a Script?
A script is a set of connected blocks that control a sprite’s behavior.
Beginner
7. What are Costumes?
Costumes are different appearances of a sprite used for animation.
Beginner
8. What are Backdrops?
Backdrops are background images used on the Stage.
Beginner
9. What is the Green Flag used for?
The Green Flag starts the execution of scripts in a project.
Beginner
10. What is a Variable in Scratch?
A variable stores data such as score, name, or number values.
Intermediate
11. What is a List in Scratch?
A list stores multiple values in a single variable structure.
Intermediate
12. What are Broadcast messages?
Broadcast messages allow communication between sprites.
Intermediate
13. What are Loops in Scratch?
Loops repeat a set of instructions multiple times (forever, repeat, repeat until).
Intermediate
14. What is Conditional Logic?
Conditional logic uses if and if-else blocks to make decisions.
Intermediate
15. What are Operators?

Intermediate
16. What is Cloning in Scratch?
Cloning creates multiple copies of a sprite during runtime.
Intermediate
17. What are Events?
Events trigger scripts, such as when green flag clicked or key pressed.
Intermediate
18. What is the difference between forever and repeat?
Forever runs infinitely, while repeat runs a fixed number of times.
Intermediate
19. How do you detect collision?
Using "touching sprite?" or "touching color?" sensing blocks.
Intermediate
20. What are Coordinates in Scratch?
Scratch uses X and Y coordinates to position sprites on the stage.
Advanced
21. What are Custom Blocks?
Custom blocks (My Blocks) allow you to create reusable functions.
Advanced
22. What is Recursion in Scratch?
Recursion occurs when a custom block calls itself repeatedly.
Advanced
23. How do you create a scoring system?
Create a variable named score and update it using change score by block.
Advanced
24. How do you create gravity effect?
Use change y by negative value inside a loop to simulate gravity.
Advanced
25. How to make a scrolling background?
Use two backdrops or sprites and continuously move them to create scrolling effect.
