Looks and Sound BlocksActivities & Teaching Strategies
Active learning works because pupils need to see and hear how Looks and Sound Blocks change their story in real time. When children pair actions with sounds and costumes, they connect cause-and-effect faster than with static explanations alone.
Learning Objectives
- 1Construct a ScratchJr script that changes a sprite's costume and plays a sound effect.
- 2Explain how 'say' blocks with different text can communicate character emotions or actions in a story.
- 3Analyze how specific sound effects contribute to the mood or atmosphere of a ScratchJr animation.
- 4Design a short animation sequence incorporating at least two costume changes and one sound effect to represent a simple event.

Pairs Challenge: Dialogue Scenes
Students pair up, choose a sprite, and build a short script: change costume, add two 'say' blocks for conversation, play a sound. Switch roles to test and tweak timings. Share one scene with the class.
Prepare & details
Explain how 'say' blocks can help tell a story.
Facilitation Tip: During Pairs Challenge, circulate with a timer so partners test one speech bubble at a time to avoid overlapping bubbles.
Setup: Flexible workspace with access to materials and technology
Materials: Project brief with driving question, Planning template and timeline, Rubric with milestones, Presentation materials
Small Groups: Mood Animations
Groups storyboard a three-part story on paper, noting costume changes, speech, and sounds for happy or sad moods. Code in ScratchJr, then play and compare group results. Vote on most effective moods.
Prepare & details
Construct a script that makes a character change costume and play a sound.
Facilitation Tip: In Small Groups, hand out emotion cards so each sound chosen has a visual reference to match.
Setup: Flexible workspace with access to materials and technology
Materials: Project brief with driving question, Planning template and timeline, Rubric with milestones, Presentation materials
Whole Class: Remix Gallery
Project student projects. Class plays each, discusses sound and look matches. Students remix one peer animation by altering a sound or speech bubble, then demo changes.
Prepare & details
Assess how different sounds can enhance an animation's mood.
Facilitation Tip: For the Remix Gallery, project one finished piece and ask the class to point out the first block that triggered the mood.
Setup: Flexible workspace with access to materials and technology
Materials: Project brief with driving question, Planning template and timeline, Rubric with milestones, Presentation materials
Individual: Personal Story Soundtrack
Each pupil creates a solo animation of their day: costume for actions, 'say' for thoughts, sounds for feelings. Save and self-assess mood fit before optional sharing.

Teaching This Topic
Focus first on sequencing: students should see that a ‘say’ block must wait for the costume change to finish before it appears. Use think-aloud modeling to show how to space blocks and when to add a short pause block. Avoid giving students pre-written scripts; instead, have them plan on paper with simple stick figures and speech lines so they internalize the flow before coding.
What to Expect
Successful learning looks like students combining costume changes, speech bubbles, and audio to tell a clear mini-story. They should explain which block they used and why it matched the mood or action.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Pairs Challenge, students believe say blocks appear instantly without any wait time.
What to Teach Instead
Hand each pair a sticky note timer and ask them to predict how long the first sprite’s wave costume should run before the speech bubble appears. Have them test and adjust until the speech bubble matches the wave.
Common MisconceptionDuring Small Groups mood animations, students think costume changes happen automatically regardless of block order.
What to Teach Instead
Give each group a strip of paper with the blocks printed in jumbled order. Ask them to rearrange the strips physically on the table before coding so they see that the ‘change costume’ block must come first.
Common MisconceptionDuring Remix Gallery, students assume multiple sound blocks will layer cleanly without pauses.
What to Teach Instead
After each group shares, replay their animation twice: once with their original timing and once with 1-second pauses between sound blocks. Ask the class to vote which version sounds clearer and explain why timing matters.
Assessment Ideas
After Pairs Challenge, circulate and ask each pair: ‘Show me the block you used to make your character wave and the block that made it talk. Which block ran first?’
After Mood Animations, hand each student a small card. Ask them to draw one costume change they made and write one emotion word that matched the sound they chose.
After Remix Gallery, display one character’s speech and two different sounds (happy vs surprised). Ask: ‘How would the story change if we swapped these sounds? Explain which sound matches the speech word and why.’
Extensions & Scaffolding
- Challenge: Ask students to add a second sprite whose costume and sound must sync with the first sprite’s wave.
- Scaffolding: Provide sticky notes with starter lines like ‘Hello!’ and ‘Goodbye!’ so students focus on timing rather than writing.
- Deeper exploration: Introduce a ‘repeat’ block so students loop a wave-and-wave-sound sequence three times to build a rhythm.
Key Vocabulary
| Costume | A different visual appearance for a sprite. Changing costumes makes a sprite look like it is moving or changing. |
| Speech Bubble | A visual element that appears above a sprite, displaying text. Used to show what a character is saying. |
| Sound Effect | A recorded audio clip that is played during an animation to add realism or emphasis to an action. |
| Script | A sequence of programming blocks that tells a sprite what to do, in what order. |
