5. Write a simple script to make a sprite move in Scratch.

• Use the 'say' block to make the sprite move.

• Use the 'broadcast' block to make the sprite move.

• Use the 'change x by' and 'change y by' blocks to make the sprite move.

• Use the 'go to x: y:' and 'glide 1 secs to x: y:' blocks to make the sprite move.

6. How can you add sound effects to your Scratch project?

8. Explain the concept of variables in Scratch and provide an example.

• An example of a variable in Scratch is 'move' which is used to control the movement of a character.

• In Scratch, variables are used to store data and can be accessed and modified throughout the program. For example, a variable named 'score' can be used to keep track of the player's score in a game.

• Variables in Scratch can only be accessed in the specific block where they are created.

• By using the 'Sensing' and 'Operators' blocks to change the background color

• By writing code in Python

• By using the 'Sound' and 'Pen' blocks to create movement

10. Write a script to make a sprite change its size continuously in Scratch.

• Use the 'change size by' block inside a forever loop.

• Use the 'set size to' block inside a repeat loop.

• Use the 'hide' block inside a forever loop.

• Use the 'go to front' block inside a repeat until loop.
