When a sprite needs to detect if it touches another sprite or color, you use a **sensing** block. **

** sensing --- ### **Section C: True or False (1 mark each)**

** sensing --- ### **section c: true or false (1 mark each)**

The "repeat" block and the "forever" block are both examples of looping structures in Scratch. **

**True --- ### **Section D: Short Answer (2 marks each)**

**true --- ### **section d: short answer (2 marks each)**

What is the purpose of the "go to x: __ y: __" block in Scratch? **

**The "go to x: __ y: __" block moves a sprite to specific coordinates on the stage, based on the given x and y values.

**the "go to x: __ y: __" block moves a sprite to specific coordinates on the stage, based on the given x and y values.

Explain the difference between the "if" block and the "if-else" block in Scratch. **

**The "if" block performs an action only if a condition is true, while the "if-else" block performs one action if the condition is true and a different action if the condition is false.

**the "if" block performs an action only if a condition is true, while the "if-else" block performs one action if the condition is true and a different action if the condition is false.

How can you make a sprite appear to glide smoothly from one position to another? **

** Use the "glide __ secs to x: __ y: __" block to make the sprite move smoothly from its current position to the specified coordinates over the specified time.

** use the "glide __ secs to x: __ y: __" block to make the sprite move smoothly from its current position to the specified coordinates over the specified time.

Describe a situation where you would use the "broadcast" and "when I receive" blocks in a Scratch project. **

**These blocks can be used when you want multiple sprites to react to a specific event. For example, broadcasting "gameOver" can signal all sprites to stop moving and display a "Game Over" screen.

**these blocks can be used when you want multiple sprites to react to a specific event. for example, broadcasting "gameover" can signal all sprites to stop moving and display a "game over" screen.

Why is it useful to use variables in Scratch projects? **

** Variables are useful for storing information that can change during the game, like scores, player health, or time, allowing the project to track and update data dynamically. --- ### **Section E: Problem Solving (3 marks each)**

** variables are useful for storing information that can change during the game, like scores, player health, or time, allowing the project to track and update data dynamically. --- ### **section e: problem solving (3 marks each)**

Write a simple sequence of blocks to make a sprite move 10 steps, wait for 1 second, and then move 10 steps back. **

** - Move 10 steps - Wait 1 second - Move -10 steps

** - move 10 steps - wait 1 second - move -10 steps

Create a sequence to make a sprite say "Hello!" if it touches the edge of the stage. If it doesn't, it should say "Not there yet!" **

** - If <touching edge?> then - Say "Hello!" - Else - Say "Not there yet!"

** - if <touching edge?> then - say "hello!" - else - say "not there yet!"

Explain how you would use Scratch blocks to create a basic counter that counts from 1 to 10 and displays the count. **

** - Set [counter] to 1 - Repeat 10 times - Show variable [counter] - Change [counter] by 1

** - set [counter] to 1 - repeat 10 times - show variable [counter] - change [counter] by 1

Design a code block sequence that changes the backdrop to "Night" when the space bar is pressed. **

** - When [space] key pressed - Switch backdrop to [Night]

** - when [space] key pressed - switch backdrop to [night]

Describe how you would create a game over message using broadcast messages in Scratch. **

** - When conditions for game over are met - Broadcast [gameOver] - When I receive [gameOver] - Show sprite [game over message] --- ### **Section F: Application (3 marks each)**

** - when conditions for game over are met - broadcast [gameover] - when i receive [gameover] - show sprite [game over message] --- ### **section f: application (3 marks each)**

A sprite should move randomly on the screen whenever the "up arrow" key is pressed. Write the Scratch blocks needed to achieve this. **

** - When [up arrow] key pressed - Go to x: [pick random -240 to 240] y: [pick random -180 to 180]

** - when [up arrow] key pressed - go to x: [pick random -240 to 240] y: [pick random -180 to 180]

Outline how you would code a basic quiz program in Scratch that asks a user a question and gives feedback on whether they are correct or incorrect. **

** - Ask "What is 5 + 3?" and wait - If <answer = 8> then - Say "Correct!" - Else - Say "Incorrect!"

** - ask "what is 5 + 3?" and wait - if <answer = 8> then - say "correct!" - else - say "incorrect!"

Describe how you could make a sprite follow the mouse pointer on the screen. **

** - Forever - Go to [mouse pointer]

** - forever - go to [mouse pointer]

Write the Scratch block sequence to create a sprite that bounces back when it hits the edge of the stage. **

** - Forever - Move 10 steps - If <touching edge?> then - Point in direction ([direction] * -1)

** - forever - move 10 steps - if <touching edge?> then - point in direction ([direction] * -1)

In a Scratch project, explain how you would code a sprite to change color every time it receives a broadcasted message "changeColor". **

** - When I receive [changeColor] - Change color effect by 25 --- **Total Marks: 50** --- This test includes the answers for each question, allowing for immediate feedback and review of Scratch programming concepts relevant to Secondary 3 Computer Applications.

** - when i receive [changecolor] - change color effect by 25 --- **total marks: 50** --- this test includes the answers for each question, allowing for immediate feedback and review of scratch programming concepts relevant to secondary 3 computer applications.
