Question 1

Question 1Carefully go through some sample scripts given below. What is happening in each of these scripts ?

Accepted Answer

Script 1When the sprite is clicked, it will repeatedly move 5 steps in the direction it's facing. If it reaches the edge of the screen, it will bounce back and continue to move 5 steps infinitely.Script 2When the sprite is clicked, it will repeatedly move 5 steps in the direction it's facing. If it reaches the edge of the screen, it will bounce back and it will also gradually rotate clockwise if it's facing right, or anticlockwise if it's facing left.Script 3When the green flag is clicked, the sprite will face to the right, resize to 60% of its original size and move to the position with coordinates (-100, -70). It will check if it's touching another sprite named "Sprite1". If it is, it will display the text "Woof!" in a speech bubble for 2 seconds.

Question 2

Question 3Create a fun game in scratch where there are two sprites on the stage cat sprite and a ball sprite. Ball is forever moving on stage. The cat sprite's movement is controlled by pressing all arrow keys : up/down/left/right. If the cat sprite touched the ball sprite, it exclaims "Hurray!!".

Accepted Answer

Question 4

Question 6Which of the following command will prevent your sprite to move off the stage ?go to x .......... y ..........set x to ..........If On edge, bouncechange x by ..........

Accepted Answer

If On edge, bounceReason — If On edge, bounce command checks to see if the sprite is on the edge of the stage. If the sprite is on the edge, then it flips the sprite around so that it faces the other way. Thus, the sprite cannot get off the stage.

Accepted Answer

(a) TrueReason — The Control category or Events category in Scratch contains blocks like "when green flag clicked" to start a script and "stop" blocks to halt the script's execution.(b) TrueReason — In Scratch, we can import our own sprite images from files to use in our projects, enhancing customization.(c) FalseReason — In Scratch, you can both grow and shrink a sprite using the "change size" block in the Looks category.(d) FalseReason — The "pen down" command in Scratch actually starts the sprite drawing on the stage, allowing it to leave a trail behind as it moves.(e) TrueReason — The background that we see on the stage is the backdrop.

Question 12What is an if-statement ? Give two examples.

Accepted Answer

The if block from Controls category is used when we have to take an action depending upon a certain condition. It allows a program to execute certain actions only if a specific condition is true. If the condition is false, the actions within the if-statement are skipped.Consider the following examples:1. If we want our sprite to move to the center of the stage when it touches the edge of stage, we can use the given script:if touching edge then
    go to x : 0 y : 0
2. If we want our sprite to say "You win" when it touches another sprite (ball), we can use the given script:if touching ball then
    say "You win"
