Third Edition

Keywords: Computing Class 4

Let’s Review 1. Database refers to any collection of data, or information, that is specially organized for rapid search and retrieval by a computer. 2. Each item of data or column in a database is called a field. Each row in a database is called a record. 3. Microsoft Access is a database management system (DBMS) used to store and manage data. 4. A field’s data type determines what kind of data it can store. 5. Every field in a table has properties and these properties define the field’s characteristics and behaviour. 6. A field is a way of organizing information by type. Whereas, A record is one unit of information. 7. Forms in Access are like display cases in stores that make it easier to view or get the items that you want. 8. Reports offer a way to view, format, and summarize the information in your Microsoft Access database.

143 6.1. What is a Computer Program 6.2. What is Scratch A computer program is a series of instructions that tell a computer to perform an action. Computer programs are a defined set of algorithms or processes that are completed in order to achieve a task. A program is created using a programming language, which allows a computer programmer to write lines of code that the computer can understand. Everything that a computer does is achieved using a program, whether that be browsing the web with or processing a document using Microsoft Word. Scratch is a free visual programming language developed to help simplify the process of creating and programming animations, games, music, interactive stories and more. With Scratch, you can program your own interactive stories, games, and animations and share your creations with others in the online community. Scratch is designed especially for ages 8 to 16 but is used by people of all ages. Millions of people are creating Scratch projects in a wide variety of settings, including homes, schools, museums, libraries, and community centres. Scratch is a project of the Lifelong Kindergarten Group at the MIT Media Lab. It is provided free of charge. In Scratch, we write programs called Script. Each script controls an object called a Sprite. The orange cat that you see when you start up Scratch is an example of a Sprite. The City School 2023-2024


144 6.3. Scratch Interface In Scratch, we write programs called script. Each script controls an object called a sprite. The orange cat that you see when you start up Scratch is an example of a sprite. Here is an example of what a script looks like. • The Stage is the background that our program runs on. • The Sprite pane shows all of the sprites that are part of our program. • The Block Palette contains the blocks that we can use to make our scripts. Each block represents one instruction in our program. We build our scripts by dragging blocks from the block palettes to the Script Area. The City School 2023-2024


Let’s Program 145 • New: creates a new project from a blank template. • Save: saves the current project in the directory from which it came from. If the project is new it opens a file browser, allowing you to save a project as a new file, except when online. • Save as a Copy: creates a copy of the current project. • Undelete: brings back a sprite, costume, sound, or script that was recently deleted. • Small Stage Layout: makes the stage shrink to a smaller size. • Turbo Mode: sets the player into Turbo Mode, where the code is executed very quickly. The duplicate button (stamp icon) duplicates anything on the screen. It duplicates sprites (in the sprites area or stage), costumes, costume selections, sounds, blocks, and scripts. The delete button (scissors icon) deletes anything on the screen. It deletes sprites (in the sprites area or stage), costumes, costume selections, sounds, blocks, and scripts. File Menu Edit Menu Duplicate Delete The City School 2023-2024


146 ? Enlarge Button Shrink Button Help All Tips Sprite Clicking on a sprite in the stage, costume editor, or a selection in the costume editor will make the sprite or selection grow bigger. Clicking on a sprite in the stage, costume editor, or a selection in the costume editor will make the sprite or selection shrink. The button opens the Tips Window. Clicking on a part of the editor or a block will give help on that section. These are informational sections with helpful tutorials and information about the scratch website itself. Each object in our program is a sprite. The default sprite is the orange cat, but you can pick from a library of different sprites. Let’s get rid of the cat. Right-click on the cat and select delete.

148 2. To add a sprite from the sprite library, click then select any sprite of your choice. 6.5. Adding Background 6.6. Script Area To add background, click to choose a new backdrop from the library. To get our sprites to animate, move, or interact with one another on the stage, we need to create one or more scripts for each sprite. If you click on a sprite from the list, the project editor will show the existing stacks of blocks in the scripts area. To create a game, story, or animation in Scratch, we stack blocks together to form a script that gives instructions to the project sprites. The City School 2023-2024


Let’s Program 149 Motion (Movement Block) In the middle of the project editor screen, we have categories of blocks that are grouped by the kinds of tasks they represent. They are Motion, Looks, Sound, Pen, Data, Events, Control, Sensing, Operators, and More Blocks. We mix the blocks together to form our artwork. Each type of block is colour coded so that we can easily identify them by their type in our scripts. Sprite is move by 10 steps in the current direction. Rotate the sprite to 15 degrees clockwise. Rotate the sprite to 15 degrees counter-clockwise. Move the sprite with the specified X and Y coordinates using the centre of the sprite. Using this block is equal to two blocks: Set X to and Set Y to simultaneously. Rotate the sprite in the specified direction. move 10 steps turn 15 degrees turn 15 degrees go to x: 0 y: 0 point in direction 90 The City School 2023-2024
