2.7 Sound Party

Identify Scratch's sound library and music extensions as resources for sounds. Use Sound Editor to cut, fade, manipulate existing sounds and/or to record new sounds.

OBJECTIVES



OBJECTIVES: By the end of this lesson, students will:

    • demonstrate knowledge of four ways to work with sound in a scratch project:

    • sound Library upload;

    • sound Editor upload;

    • upload from your computer

    • inbuilt notes and drums.

TEACHER RESOURCES:

Standards

    • CSTA 2-AP-12: Design and iteratively develop programs that combine control structures, including nested loops and compound conditionals.

    • CSTA 2-AP-16: Incorporate existing code, media, and libraries into original programs, and give attribution.

CSTA

Mini-Lesson (5-10 minutes)

    • Students can continue working in the fish project 2-8, or make a new project from scratch and add three sprites and a backdrop.

    • Students need to turn in a scratch project that uses three types of sounds, as in the example project.

      • a sound from the Sound Library.

      • a manipulated sound or new recording using the Sound Editor.

      • a built-in sound (notes/drums)

        • note: students can also upload a sound - but this optional -not part of the student checklist.

    • Video (1.5 minutes) -how to add sounds from the Sound Library, -how to create sounds in the Sound Editor, - how to Upload Sounds.

Project (20-30 minutes)

TEACHER GUIDANCE:

Students sometimes run into problems, importing sounds from the Sound Library into their scratch project. Make sure that in the sound library, the file is highlighted ( grey box around sound file) , before clicking OK, otherwise the sound is not added to scratch project.

Tips of reusing code:

    • Move code from one sprite to another sprite. (Video)

    • Move between scratch projects:

      • Use backpack to keep code between scratch sessions.

      • Download sprite to your computer then upload it to a new scratch project. Make sure to give credit.

Close-Out (5 minutes)

Close-Out (5 minutes)

Discuss the following questions:

    1. Where can you find sounds to use with your scratch project.

    2. Where can you manipulate sounds or record new sounds?

    3. Why might this be important to reuse code?

Potential Responses

  1. Sounds Tab, and go to sound Library, or Sound Editor, or upload.

  2. Sound Editor

  3. A lot of sprites may have similar code. Duplicating the sprite or reusing a portion of that sprite code saves time. Note: It you use another's code, give them credit.
