Study Notes

A sprite is a graphical object that can be programmed to perform actions in Scratch
Sprites can be created, duplicated, and deleted
Each sprite has its own set of costumes, sounds, and scripts
Sprites can be controlled using blocks, which are the fundamental programming elements in Scratch

Conditionals allow scripts to make decisions based on certain conditions
There are two types of conditionals in Scratch: If-Then Blocks and If-Then-Else Blocks
If-Then Blocks: execute a set of blocks if a certain condition is true
If-Then-Else Blocks: execute one set of blocks if a condition is true, and another set of blocks if the condition is false
Conditionals can be used to create interactive stories, games, and simulations

Variables are used to store and manipulate data in Scratch
Variables can be used to keep track of scores, lives, and other game-related data
There are two types of variables in Scratch: User-Defined Variables and System Variables
User-Defined Variables: created by the user to store specific data
System Variables: built-in variables that provide information about the Scratch environment, such as the date and time
Variables can be used in scripts to create dynamic and interactive programs
