Question 1

Question 1Navdha is playing a game created by her teacher using Scratch. The game works like this :An item/thing name is shown on screen and then the screen shows moving images of multiple things/sprites. The player has to click on correct image/sprite as per displayed name. If the player clicks on correct sprite/image, a ball sprite in the right corner starts jumping and clap sound also plays. If the player wants to move to next thing/item, the player can press a space bar.(a) Identify the concepts/features of Scratch used in this game.(b) Which concept/feature is used to move to next item if space bar is clicked ?(c) Which concept/feature is used to tell ball sprite that correct image/sprite has been clicked.

Accepted Answer

(a) The concepts/features of Scratch used in this game are as follows:Sprites — The moving images of multiple things/sprites are used to represent the different items.Costumes — Each sprite likely has multiple costumes to show different visual representations.Click events — The player interacts with the game by clicking on the correct sprite.Sounds — The game plays a clap sound when the correct sprite is clicked.Keyboard events — The game detects when the space bar is pressed to move to the next item.Conditional blocks — There are conditional checks to determine if the correct sprite is clicked, triggering the response with the ball sprite and clap sound.Iteration blocks — Iteration blocks are used to make the game run continuously.Passing messages between sprites — The game uses the broadcast block to send message to ball sprite telling that correct sprite has been clicked.(b) The Events feature is used to move to next item if space bar is clicked. The programmer uses the command when space key pressed so that the game listens for the space bar key press event and uses this event to advance to the next item.(c) The broadcast block from events category is used to tell ball sprite that correct image/sprite has been clicked.

Question 2

Question 1(b)Write Scratch programs to draw these shapes :

Accepted Answer

Please refer to the full solution above.

Question 3

Question 2Create a Guessing game where your sprite generates a number (Host Number) in the range 10 to 99 (*Use Random number generator for this).User is then asked to 'Guess this number' (userGuess) and given 5 chances to do this (*5 times loop)If the user's number (i.e., UserGuess) is same as HostNumber, then your program should display "You Win" and plays a drum sound. If user is not able to guess the number thenfor every unsuccessful guess, display message "Try again" with a drum sound play.After 5 unsuccessful guesses, display, "Sorry buddy, you lose. My number was <Host Number>", with a drum sound.

Accepted Answer

Please refer to the full solution above.

Question 4

Question 3Write a Scratch program to draw this

Accepted Answer

Please refer to the full solution above.

Question 5

Question 4Write an interactive program in which the sprite is crazily drawing on stage forever. But if the user presses a space bar, the pen size and pen colour change along with a sound play.

Accepted Answer

Please refer to the full solution above.

Question 6

Question 6Which predefined variables of sound can you use to control the loudness and play-speed of sound, respectively ?

Accepted Answer

We can use the volume and tempo to control the loudness and play-speed of sound, respectively.

Question 7

Question 7What all can you do through Data category of blocks ?

Accepted Answer

Data blocks let us create and manipulate data in our animations and games. We can create two types of data: variables and lists. These can be used with sprites and with the stage.When we specify the name of a variable, we can also specify if the variable is a local variable or a global variable. Once the variable is created, it is available through the Data block and the commands used to manipulate the variable are also available in the Data block.

Question 8

Question 8What is the difference between repeat and repeat until blocks ?

Accepted Answer

Repeat block iterates a specified number of times whereas repeat until block repeats as long as the given condition is false.

Question 9

Question 9What is the difference between repeat and forever blocks ?

Accepted Answer

Repeat block is a finite iteration block i.e., it iterates a specified number of times whereas forever block is an infinite iteration block i.e., it keeps repeating the commands inside it over and over again.

Question 10

Question 10What is the difference between if and if-else blocks ?

Accepted Answer

The if block is used when we have to take action depending on a certain condition being true whereas the if-else block is used when we have to take different courses of action depending upon whether the condition is true or false.

Question 11

Question 11What is the difference between say and ask blocks ?

Accepted Answer

The differences between say and ask blocks are:Say block is used to represent speech by sprites whereas ask block is used to prompt something to user asking for a value or response.Say block displays a specific speech block in the speech bubble which appears on the screen for a specified amount of time whereas ask block provides a place for the message to be displayed and waits for the response.Say block doesn't prompt the user for any response whereas ask block provides an input box where the user can type his response.Say block is available under looks category whereas ask block is available under sensing category.

Question 12

Question 12To send a message to all the sprites in the program, which block will you use ?

Accepted Answer

We will use broadcast <message> block from Events category to send a message to all the sprites in the program.
