An Introduction to Scratch Programming

The sprite will move backward with the specified steps

Step 1: The 'move' block in the Motion category shifts the sprite a definite number of steps on the stage. Step 2: By default, the steps parameter is set to 10, which moves the sprite forward. Step 3: When the parameter is set to a positive value, the sprite moves forward by that many steps. Step 4: When the parameter is set to a negative value (like -100), the sprite moves backward (in the opposite direction) by those many steps. Step 5: Setting steps to a negative value does NOT stop the sprite, make it disappear, or rotate it – those are the functions of other blocks.

Pen

Step 1: Most block categories in Scratch are available by default when you open the software. Step 2: Categories like Events, Operators, Variables, Motion, Looks, Sound, Control, Sensing, and My Blocks are all available by default. Step 3: However, the Pen block category is NOT available by default. Step 4: To use the Pen block, you must click the 'Add Extension' button located at the bottom-left corner of the Scratch window. Step 5: After clicking 'Add Extension', you select the Pen extension, and it then appears at the bottom of the block categories. Events and Operators are always present,

Click File → Select 'Save to your computer' → Enter file name → Click Save

Step 1: To save a Scratch project, always start by clicking the 'File' option on the menu bar. Step 2: A dropdown list appears with three options: New, Load from your computer, and Save to your computer. Step 3: You must select 'Save to your computer' – this opens the Save As dialog box. Step 4: In the dialog box, select the drive where you want to save, type the file name, and click the Save button. Step 5: 'Load from your computer' is for opening an existing file (not saving), 'New' creates a new project, and the Edit menu is not used for saving – so those options are all incorrect.

Looks category; it increases the size of the sprite by 10%

Step 1: The 'change size by' block deals with the appearance (size) of the sprite. Step 2: In Scratch, anything related to a sprite's appearance belongs to the Looks block category (coded in purple colour). Step 3: When the parameter is set to 10 (positive), the sprite grows by 10% each time the block is executed. Step 4: If the parameter is set to -10 (negative), the sprite shrinks by 10%. Step 5: The Motion category handles movement, Control handles loops and decisions, and Events handle triggers – none of them control sprite size. So the Looks category with 10% growth is the correct answer.
