Introduction & Learning Objectives
Learning Objectives
Identify an event that can trigger an animation.
Create a simple animation sequence, like a walking motion, using multiple costumes.
By the end of this lesson, students will be to use a loop to make an animation repeat.
Add a visual effect (like color change or ghost) to a sprite.
Synchronize a sound effect with an action or animation.
Use a conditional (if-then) to trigger an effect when something happens, like a sprite being clicked.
Have you ever wondered how characters in your favorite cartoons or video games move and talk? Let's learn how to bring our own digital stories to life! ✨
Today, we will learn how to make our computer characters, called sprites, move, change, and make sounds. This is called animation! Learning this helps make our digi...

Key Concepts & Vocabulary
TermDefinitionExample
AnimationMaking something look like it's moving by showing different pictures one after another, very fast.A flipbook where each page has a slightly different drawing of a stick figure. When you flip the pages quickly, the stick figure looks like it's running.
SpriteA character or object in your project that you can give instructions to.A cat, a spaceship, or a bouncing ball that you add to your digital story.
EventA trigger that tells your code to start running. It's the 'when' part of an instruction.Using a 'when green flag clicked' block to start the whole story, or a 'when this sprite is clicked' block to make a character jump.
SequenceA set of instructions that happen in a specific order, one after the other.A sprite&...

Core Syntax & Patterns
The Event Trigger Pattern
WHEN [event happens], DO [sequence of actions]
This is the most important pattern for making things interactive. You choose a trigger (like a click) and then list all the actions you want to happen right after.
The Animation Loop Pattern
FOREVER { DO [action 1], WAIT, DO [action 2], WAIT }
To make a smooth animation that repeats, you put the actions inside a 'forever' loop. Adding a small 'wait' block between actions stops them from happening too fast to see.
The Conditional Effect Pattern
IF [something is true], THEN [apply an effect]
Use this to make your project react to things. For example, you can check IF a sprite is touching a certain color, and THEN make it change its own color or disappear.

Challenging
A game has a score that starts at 0. A 'You Win!' message should appear only when the score is exactly 5. What two things must happen in the game for the message to appear?
A.The player clicks the green flag, and the score becomes 1.
B.The score must increase to 5, and the program must check if the score is 5.
C.The player must click a character 10 times.
D.The 'You Win!' message must be hidden, and then the score must be 0.
Challenging
Your character's running animation looks too fast and choppy. It is just a 'move 10 steps' and 'next costume' block inside a loop. What block could you add inside the loop to make the animation smoother and slower?
A.'wait 0.1 seconds' block
B.'stop all' block
C.'change size by 10' block
D.'play sound' block
Challenging
You are animating a sun that rises and sets. To make it set, you use a 'glide 1 secs to x:__ y:__' block. What data do you need to figure out to make the sun set below the horizon?
A.The color of the sun
B.The current time on the clock
C.The name of the background
D.The x and y coordinates of a spot below the horizon
