Scratch Programming Quiz

What is the main issue with changing numbers in multiple locations in a Scratch program?

• It can lead to inconsistencies and errors.

• It makes the program more secure.

• It makes the program run slower.

• It increases the file size of the program.

What is the primary benefit of using variables in a Scratch program?

• They allow for easy updates to values used multiple times.

• They reduce the number of blocks needed.

• They increase the speed of the program.

• They make the program look more complex.

How can you create a variable in Scratch?

• By using a special keyboard shortcut.

• By clicking the 'Make a Variable' button.

• By typing it directly into the code.

• By importing it from another program.

Why is it beneficial to use a variable for controlling text display time?

• It makes the text display faster.

• It reduces the number of blocks needed.

• It makes the text appear in different colors.

• It allows for consistent timing across different text blocks.

What can you do with variables besides storing values?

• Create new sprites.

• Perform mathematical operations.

• Use them to change the background color.

• Change the language of the program.

What is the purpose of using operator blocks in Scratch?

• To change the appearance of sprites.

• To perform mathematical operations with variables.

• To create sound effects.

• To animate sprites.

What is a potential issue when using global variables in Scratch?

• They make the program run slower.

• They cannot store numerical values.

• They can cause timing issues between sprites.

• They can only be used by one sprite.

How can you resolve timing issues with global variables in Scratch?

• By using only local variables.

• By reducing the number of variables.

• By adding wait blocks to control timing.

• By using more sprites.

What is the difference between global and local variables in Scratch?

• Global variables can only store numbers, while local variables can store text.

• Local variables are automatically updated, while global variables are not.

• Local variables are faster to access than global variables.

• Global variables can be accessed by all sprites, while local variables are specific to one sprite.

What should you do if a global variable does not update as expected?

• Delete the variable and create a new one.

• Click the green flag twice or add wait blocks.

• Restart the Scratch program.

• Change the variable to a local variable.
