WorksheetsMouse Trails in Scratch - Multiple-Choice Test
Total questions: 21
Worksheet time: 11mins
What is the goal of this tutorial?
To make a sprite move randomly
To create a mouse trail in Scratch using clones
To design a maze game in Scratch
To create pixel art using Scratch tools
What is the first step to creating a mouse trail?
Choosing a sprite to follow the mouse pointer
Setting the sprite size to a smaller value
Changing the sprite's X and Y positions
Adding the 'repeat' block
What block is used to make a sprite follow the mouse pointer?
'Go to random position'
'Go to mouse pointer'
'Change X by 10'
'Set ghost effect'
How is the sprite programmed to follow the mouse pointer continuously?
By using a 'repeat' block
By putting 'Go to mouse pointer' inside a forever loop
By duplicating the sprite
By changing the sprite’s costume
What block is used to create duplicates (clones) of the sprite?
'Duplicate this sprite'
'Create clone of myself'
'Repeat'
'Switch costume'
6. How can clones be programmed to behave differently from the original sprite?
By using different scripts for clones
By changing the original sprite's costume
By deleting the original sprite
By renaming the original sprite
How are clones created in Scratch?
By using the 'Create clone of myself' block
By using the 'When I start as a clone' block to add code for clones
By changing the sprite’s size
By setting the sprite’s direction
How can clones disappear after completing their behavior?
By hiding the sprite
By adding the 'Delete this clone' block after their actions
By changing their size to zero
By setting their X position off-screen
Why is it safe to use 'Create clone of myself' inside a forever loop in this project?
Because clones are deleted after their actions, preventing performance issues
Because Scratch automatically limits the number of clones
Because the forever loop pauses after each clone is created
Because the clones are created at random intervals
How can the clones be made to move upward in the mouse trail?
By adding 'Change X by 10' inside a repeat loop
By adding 'Change Y by 10' inside a repeat loop
By using the 'Go to random position' block
By setting the sprite’s costume to a new one
How is the falling effect for the clones achieved?
By setting the X position to zero
By adding 'Change Y by -10' inside a repeat loop
By using 'Go to mouse pointer'
By changing the sprite size
What block is used to create an explosion effect for the mouse trail?
'Point in direction' with 'Pick random' set to 0-360 degrees
'Change X by 10'
'Set ghost effect'
'Create clone of myself'
How can the size of the clones decrease as they move outward?
By adding 'Change size by -8' inside the repeat loop
By setting the sprite size to 10
By using the 'Set size to 50%' block
By creating smaller clones initially
What block is used to make clones fade as they move outward? ('05:19-05:48')
'Change color effect'
'Set ghost effect'
'Change ghost effect by 5'
'Delete this clone'
What happens when the 'Change ghost effect by 5' block is added? ('05:19-05:48')
The clones change color
The clones get more transparent as they move outward
The clones grow larger
The clones stop moving
How can the clones be made to rotate as they move outward?
By adding 'Point in direction'
By using 'Turn' inside the repeat loop
By changing the ghost effect
By duplicating the sprite
What does the tutorial recommend for experimenting with the mouse trail effects? ('Throughout the tutorial')
Using only specific blocks
Trying different blocks inside the repeat loop
Keeping the code simple and unchanging
Using pre-designed costumes only
How can the object in the mouse trail be changed?
By duplicating the sprite
By selecting a new costume in the Costumes tab
By creating a new sprite
What effect does 'Move 10 steps' have when added to the repeat loop? (*04:11–04:49*)
Clones move randomly
Clones move forward in the direction they're pointing
Clones disappear immediately
Clones change size
How does the tutorial suggest modifying the mouse trail effect?
By adding different effects like fading, shrinking, or turning
By using only default settings
By avoiding changes to the repeat loop
By adding only motion blocks
Why is the 'Delete this clone' block important in the project?
To stop clones from overlapping each other
To prevent too many clones from being created and slowing down the program
To allow the main sprite to move freely
To reset the sprite’s position
