Lesson 1: Introduction to Scratch and the Terminology
What you will learn:
- How to create a Scratch account
- The terminology used in this course for different parts of Scratch Studio
- What the different tabs for code blocks contain and what they do
Creating a Scratch Account
- Go to http://www.scratch.mit.edu
- On their homepage click
- Fill out all of the information and pick a username and password that you will REMEMBER. *You will also need an email*
Terminology – Parts of the Page
- The Stage: Where your program will perform when finished
- The Hub: Where you can find all of the code blocks Scratch has
- The Code Table: Where you will place all your code blocks to program your sprite.
Terminology – A Sprite
- A Sprite: Like an actor on a stage, your sprite reads your code blocks and performs the code you’ve created on the stage.
The Hub – The Scripts Tab
- In the Scripts Tab you find all of the available code blocks you can use to program your sprite
- There are ten smaller tabs under the Script tab.
The Five Most Used Tabs
- The tab controls how your sprite moves around the stage.
- The tab controls what color your sprite is and what costume your sprite wears.
- The tab controls when the whole program will start.
- The tab controls when different parts of the program start.
- The tab controls when sounds play and how loud they are.
- The Other Five
- The tab controls how your sprite reacts when conditions change. Example: When your sprite touches green it spins very fast but when it touches yellow it slows down.
- The tab helps your program do math. Example: You make a Basketball Game, when the basketball goes inside of the basket an operator will add 1 point to your point total.
- The tab work much like a pen in real life, it helps you and your sprite draw in your program. You can change the color, the thickness or the shade of the pen’s ink.
- The tab allows you to create your own variables and is similar to the tab but you have more control over how many sprites it controls in your program.
- The will only work if you have a Scratch compatible device attached. If you have one, you can control small machines with your Scratch code.
Compatible Device are:
- MaKey MaKey
- LEGO WeDo Kit
- PicoBoard (also known as ScratchBoard)
- Kinect2Scratch, using Microsoft Kinect
- GoPiGo for Raspberry Pi
The Hub – Costumes Tab
- In the Costumes Tab you can add costumes for your sprite to change to during your
- The lets you choose a sprite from Scratch’s extensive catalog of pre-drawn sprites
- The lets you draw a sprite of your own to use in your program.
- The lets you upload a picture from your computer to use as a sprite.
- The lets you take a picture using the webcam on your computer. *Not all computers have webcams*
- The Hub area for the Costumes Tab lets you control how many costumes your sprite has.
- The area to the left of the Hub is where you can edit your sprite by changing it’s color or draw on it.
The Hub – Sounds Tab
- In the Sounds Tab you can add sounds to your program from the Scratch library or from your own computer
- The lets you choose a sound from Scratch’s extensive catalog of pre-recorded sprites.
- The lets you record your own sounds using the mic on your computer.
- The lets you upload sounds from your computer.
