What is the purpose of the stage in Scratch?

• The stage is a tool for editing sound effects.

• The stage is the area where sprites display their actions and animations.

• The stage is used to store sprites permanently.

• The stage is where code blocks are created.

Answer explanation

The stage in Scratch serves as the main area where sprites perform their actions and animations, making it essential for visualizing the project. The other options do not accurately describe the stage's primary function.

How do you add sound to a Scratch project?

• Drag and drop a sound file onto the stage.

• Record your voice directly in the 'Scripts' area.

• Click on the 'Sounds' tab, choose or upload a sound, and use sound blocks to play it.
