- 3. • Scratch is a programming language. • Programming in Scratch is very easy, including animation and games. • It is a very useful tool for young kids or creators to learn and implement coding logic. • It was developed by MIT’s Media Lab in 2007. 3
- 4. 4 • Script is a set of instructions that are used to create a Scratch program. • It is a stack of blocks that are connected with each other and perform the specified tasks. • Scripts are used to interact with sprites and tell them what to do or say.
- 5. 5 • There are objects and characters that could be added to a program to perform actions based on code written in scripts in a project using blocks, these objects and characters are known as Sprite. • You can add a prebuilt sprite or create a new sprite as per your requirement.
- 6. 6 Suppose you want to attach any instrumental blocks or beats to your scratch project then you need to determine how fast your note has to play. Whether you want to play the same beat for 60 seconds you want to play 3-4 beats for some time period. This control of the speed of instrumental beats in Scratch is known as Tempo.
- 7. 7 • Events in Computer Science refer to the trigger, which makes anything happen when any button is clicked or any action has happened. • In Scratch, events are represented by Yellow color blocks, which include when the flag is clicked, when the sprite is clicked, when the key is pressed, etc.

- 9. 9 • Coding blocks are some pre-defined blocks of code that make writing statements of code very simple in Scratch. • You can use any coding blocks by simply dragging and dropping as per your requirements. • There are various other coding blocks available, and also you and create your blocks too
- 10. 10 • Loops in Scratch or any programming language help you execute the same line of code with or without different values for ‘n’ a number of times. You can either set the number of times or set a condition to end the loop. Scratch supports the following loops: repeat, forever, repeat until • Conditions in Scratch are implemented using Control Block. You can use control blocks to check for a condition and based on if the condition is true or false, the required code/script can be executed. Two of the most popular control blocks are: if-then, if-then-else
