Scratch Programming - Basic to Expert

Explore Scratch motion blocks from moving by steps to using coordinates, random positions or the mouse pointer, and compare glide versus go to for smooth animations.

Learn Scratch motion blocks, including point in direction, change and set X and Y, on edge bounce, rotation styles, and displaying current position and direction.

Explore sprite costumes in Scratch, edit costumes, switch between costume one and costume two to show standing and running visuals, and use looks blocks to display costume number and name.

Learn to assign and edit sounds for Scratch sprites, including importing sounds, managing multiple sounds per sprite, trimming and adjusting speed and volume, and triggering sounds on sprite clicks.

Explore the Scratch looks category by using say and think blocks to display speech and thought bubbles, switch costumes and backdrops, and change sprite size.

Explore the looks blocks in Scratch, adjust color, brightness, transparency, mosaic, and fisheye effects, and control visibility, layering, costumes, backdrops, and sprite size.

Explore Scratch sound blocks, including play until done, start and stop sounds, recording your own, and applying pitch, pan, and volume effects with set versus change.

Explore how Scratch events trigger responses, from green flag, key presses, and sprite clicks to backdrop switches, causing sprites to move, speak, or display messages.

Explore Scratch events by using loudness and timer to trigger actions, and master inter-sprite communication through broadcasts and the broadcast message wait, with practical examples.

Explore scratch operators like plus, minus, multiply, divide, and random, and use them with motion and looks blocks; learn greater than, less than, and equal to for true/false decisions.

Explore and, or, and not operators in Scratch, working with boolean values to see how true and false outputs depend on input combinations.

Explore scratch operators such as join, length, and contains, and use a variable in concatenated form at the index; apply floor, ceiling, and round to remainder in modular mathematics.

Explore Scratch control blocks, including wait, repeat, and forever, plus if and if-else, demonstrating glide actions, booleans, sensing touches, and landing messages like landed on earth.

Explore Scratch's control blocks—wait until, repeat until, and stop—through a cat gravity demo, keyboard jump, edge collision, and script stopping options (all, this script, and other sprites).

Discover how Scratch clones work by creating, showing, and deleting duplicates to spawn enemy clones that appear at random x positions and move from top to bottom.

Explore Scratch sensing blocks, including touching and distance, to detect sprites, edges, colors, and the mouse pointer. Use ask and wait, answer storage, and key press detection to drive interactivity.

Explore Scratch sensing blocks such as mouse down, mouse X and Y, drag mode, loudness, timer, and backdrop. Use volume, current year, month, days since 2000, and username in projects.

Discover what a variable is in Scratch: a changeable value with a name stored in memory. Use variables to make code flexible and avoid hard-coded values.

Explore global variables, readable and writable by all sprites, and local variables, owned by their creator; see how Sam and Ben interact with score and team in Scratch.

Explore scratch variables from local and global scopes, and use score with set, change, show, and hide blocks as a cat moves and touches the edge.

Explore how lists in Scratch store multiple items beyond single variables. Learn to create local lists, add, insert, delete, and replace items, and show or hide lists on screen.
