Understanding If-Then-Else Blocks in Scratch

The video tutorial explains the if-then-else block in Scratch, focusing on how it executes different code based on a boolean condition. Boolean blocks, which are hexagon-shaped, determine whether the condition is true or false. A practical example is provided using a cat sprite, where the sprite says 'hello' if the mouse pointer is touching it, and 'goodbye' otherwise. The tutorial concludes with a resource for further learning about Scratch programming.

What does the if-then-else block do in the control category?

• Runs code if a condition is true and skips if false

• Runs some code if a condition is true and other code if false

• Runs code continuously

• Stops the program

What shape are boolean blocks in Scratch?

• Square

• Circle

• Hexagon

• Triangle

What happens if the boolean block is true when the if-then-else block runs?

• The code inside both parts of the block runs

• The code inside the bottom part of the block runs

• The code inside the top part of the block runs

• The program stops

What will the cat sprite say if the mouse pointer is touching it when the space key is pressed?

• Goodbye

• Nothing

• Hello

• Welcome

What type of block is the 'touching mouse pointer' block?

• Looks block

• Control block

• Boolean block

• Motion block

What happens if the mouse pointer is not touching the cat sprite when the space key is pressed?

• The cat sprite says hello

• The cat sprite says goodbye

• The cat sprite moves

• Nothing happens
