When is Scratch Day?
MAY 14, 2016
What is Scratch? Developed by the Lifelong Kindergarten Group at the MIT Media Lab, Scratch is a free programming language and online community that enables young people to create and share their own stories, games, animations, and more!

What is Scratch Day? Scratch Day is a global network of events that celebrate Scratch—and the young people who code and create with it. During Scratch Day, kids and adults gather to share projects and learn from one another.
How can I participate? Visit the Scratch Day site to learn more about hosting a Scratch Day in your community or organization! To learn more about hosting, review tips and activity ideas for hosts, download logos and assets, and register a local event, visit:

What Makes Up a Scratch Project?
What is Scratch?
A computer doesn’t have a smart brain like you, so everything you want it to do must be broken down into lists of simple instructions called programs. Giving instructions to the computer is known as programming, or coding.
Here’s a Scratch project. Think of it like a play. The action takes place in an area called the stage. The “actors” (the sprites) are controlled by lists of instructions (the scripts). Behind is the backdrop —the “scenery,” which can be changed.

Backdrop (background picture) A program is a list of instructions for the computer
What Does a Computer Understand? Instructions for computers have to be written following special rules and using only words the computer understands. These words and rules make up a “programming language.” There are lots of different programming languages. Many have funny names, such as JavaScript, C++, and Python.

Scratch is a computer programming language that’s easy for beginners to use. In Scratch, programs are made by joining together colored blocks using the mouse. These groups of blocks (called scripts) tell characters on the screen (called sprites) what to do. Scratch is free, safe, and fun to experiment with.
This is an example of a script. It makes the shark sprite bounce around the stage, opening and closing its mouth. Each block gives an instruction to the sprite. A block might tell a sprite to move, change how it looks, talk in speech bubbles, react to other sprites, or make a sound.

Scratch Projects With Scratch, you can make your own interactive stories, animations, games, music, and art. Scratch has large collections (or “libraries”) of cool graphics and fun sounds you can play around with. Let your imagination run wild—you’ll soon pick up the coding skills you need!

Why is it called Scratch? “Scratching” is a way of mixing different sounds to make new music. The Scratch programming language enables you to mix pictures, sounds, and scripts to make new computer programs. data Information—for example, numbers or words. debug To remove bugs; to find and fix the errors in a program.
operating system (OS) The program that controls everything on your computer, such as OS X or Windows. run To start a program.
event Something that happens on the computer, like a mouse click.
script A stack of instructions that are run in order.
input Data that goes into a program; for example, from the keyboard.
sprite A picture on the stage that a script can move and change.
library A collection of sprites, sounds, or costumes.
stage The area containing the sprites, where a Scratch project runs.
loop An instruction that makes other instructions repeat.
string The word used by programmers for data that contains words.
condition A “true or false?” question that is used to make a decision in a computer program.
program A list of instructions that tell a computer what to do.
costume The picture a sprite shows on the stage.
operator A block that works something out from data, such as adding two numbers together.
variable A place to store data in a program. A variable always has a name and a value.
backpack A way to copy things between Scratch projects. block An instruction in Scratch. Blocks can be joined together. bug A mistake in a program. It’s called a bug because insects got into the wiring of the first computers, causing errors.
