Scratch is a visual programming language that teaches programming concepts through interactive projects made with sprites. Projects are made up of sprites, which are objects that can be programmed. Sprites have scripts, which are blocks of code that control the sprite's behavior. The stage is the background where sprites interact. Users can create new sprites from the library or upload their own images and sounds. Changing a sprite's costume changes its appearance, while changing the stage backdrop changes the background.

1. SCRATCH-

called__________
a. Sprites b. Scripts c. Blocks
2.Snapping the blocks together into stacks is
called__________
a. Costume b. Stage c. Script
3._________block will make the cat’s legs move,
which will appear like it is running.
a. Next Costume b. Motion c. Pen Down
4._________Sprite button us used to create a new
sprite.
a. Draw New b. Paint New c. Select New
5.The_____block runs the script continuously until
the stop button is pressed.
a. Motion b. Looks c. Forever
Write ‘T’ for True and ‘F’ for false statements.
1.A Script is a small character that performs
actions on the stage-F

3. 2.You can change how a sprite looks by giving it a
different costume-T
3.The stage of scratch window is 580 units wide
and 380 units high-F
4.You can upload own image from the camera as a
sprite on the stage-T
5.You can work with more than one sprite-T
C. Fill in the blanks:
1.Scratch provides four different options for
adding sprite to your applications.
2.Stage provides the canvas upon which sprites are
displayed and interact with one another.
3.Wait 1 secs block slows down the cat and
enables us to see what’s going on.
4.By default, the background of stage is white in
color.
5.Green flag is used to start your main program in
scratch window.
Differentiate between the following:
Upload Sprite from File Choose Sprite from
library

4. Can upload any image
or sprite from the file
stored on your
computer.
Provides access to
different collections of
graphic files that you
can add to your scratch
applications as sprites
2.
Sprites Scripts
Scratch projects are
made up of objects
called sprites
Scripts(program)are
created by snapping
blocks together.
Answer the following questions:
1.What do you mean by scratch
Scratch is a fun based visual programming
language to introduce basic programming concepts
in an interactive manner for kids.
2.In how many ways can we generate a new
sprite? Name them.
Scratch provides four ways to generate a new
sprite.
-Choose sprite from library
-Paint or create a new sprite

5. -Upload sprite from file
-Upload sprite from camera
3.What does changing the costume mean?
Sprites can change their look to any of its costume.
It can have one or more costumes, allowing it to
change its appearance as the application executes.
4.What is the need of changing backdrop of stage?
To make it more interesting and lively we change
the backdrop of the stage.
5.What do you mean by sprite position on stage?
The stage is the background of the project,
but can have scripts, backdrops (costumes), and sounds,
similar to a sprite.
