IF THEN ELSE REPEAT UNTIL in Scratch Programming

What is the purpose of conditional statements in Scratch programming?

• Conditional statements in Scratch programming are used to create animations.

• Conditional statements in Scratch programming are used to make decisions based on certain conditions.

• Conditional statements in Scratch programming are used to play sounds.

• Conditional statements in Scratch programming are used to change the background color.

How do you create an if-then block in Scratch?

• Click on the 'if' button in the toolbar

• Type 'if' directly into the scripting area

• Use the 'repeat' block instead

• Drag the 'if' block from the Control category onto the scripting area and add conditions inside.

When is the if-then-else block used in Scratch programming?

• When you want to create conditional statements in Scratch programming.

• When you want to create loops in Scratch programming.

• When you want to play sounds in Scratch programming.

• When you want to define variables in Scratch programming.

Explain the concept of repeat until loop in Scratch.

• The repeat until loop in Scratch is used to execute a block of code only once.

• In a repeat until loop in Scratch, the condition is checked before executing the block.

• The concept of repeat until loop in Scratch is to repeat a set of blocks until a specified condition is true.

• Repeat until loop in Scratch is similar to a forever loop.

Give an example of using the 'if' block in a Scratch program.

• If [score] is even, then say 'You win!'

• Example: If [score] > 10, then say 'You win!'

• If [score] = 10, then say 'You tied!'

• Example: If [score] < 10, then say 'You lose!'

What happens if the condition in an if-then block is not met?

• The code inside the if-then block will not be executed.

• The code inside the if-then block will be executed twice

• The program will crash

• The condition will be ignored

How can you nest if-then-else blocks in Scratch?

• Place an if-else block inside another if or else block.

• Use a repeat block to create nested if-then-else logic.

• Place an else block inside an if block.

• Connect multiple if-then-else blocks with a broadcast message.

What is the significance of the 'repeat until' block in Scratch?

• The significance of the 'repeat until' block in Scratch is to repeat a set of code until a specified condition is true.

• The 'repeat until' block in Scratch is designed to execute code only once

• The 'repeat until' block in Scratch is used to reverse the order of code execution

• The 'repeat until' block in Scratch is used to skip a specified number of iterations

In Scratch programming, what does the 'if' block evaluate?

• Variable

• Condition

• Loop

• Function

How do you change the condition in a repeat until loop in Scratch?

• Modify the condition inside the loop block

• Add a new loop instead of modifying the existing one

• Change the condition outside the loop block

• Delete the loop and start over
