Lesson 2 Animations

Lesson Materials

You need your journals again.

Overview

Play with visuals and audio in these activities focused on animation, art, and music. Explore Scratch’s focus on media – and the key computational concepts of loops, events, and parallelism – by building your own band, designing animated creatures, and creating a music video for a favorite song.

Performing scripts

Programming in Scratch is like directing theatre. In theatre, just as in Scratch, there are characters (sprites, in Scratch parlance), costumes, backdrops, scripts, and a stage. Scratch programming utilizes cues called “events,” which signal when things should occur in a project, such as: activating a project (when green flag clicked), triggering sprites’ actions (when this sprite clicked), or even sending a silent cue across sprites or backdrops (broadcast)

girl performing scripts In the image on the left, we have a girl ready to introduce a singer. Here is her script:

  1. Walk across the room.

Wait, script change reset one

  1. Walk across the room talking to the audience.

Wait, script change reset two

  1. Walk across the room talking to the audience while a singer comes to the microphone in the center of the stage.

Wait, script change reset three

  1. Walk across the room talking to the audience while a singer comes to the microphone in the center of the stage.
  2. Have the singer begin to sing after the girl stops talking.

Concepts

  • Events: one thing causing another thing to happen
  • Parallelism: things happening at the same time through
    performance
  1. Which reset causes an event?
  2. Which reset causes parallelism?

 

Reflection Prompt:

  1. What are the different ways that actions were triggered?
  2. What are the mechanisms for events in Scratch?
  3. What were the different ways in which things were happening at the same time?
  4. What are the mechanisms that enable parallelism in Scratch?

Build-a-Band Activity 1

In this activity, you will create interactive instruments. I encourage you to experiment with different ways to express sounds in Scratch by exploring other blocks in the Sounds category or by using the editing tools within the Sounds tab. If you are working alone, use parallelism to create a band sound, otherwise, in a class, we will create a band sound together.

Reflection Prompt:

  • What did you do first?
  • What did you do next?
  • What did you do last?

Orange Square, Purple Circle Activity 2

My orange circles and purple squares projectBy completing this activity, you will:

  • express your creativity by completing an arts-themed
    challenge
  • gain more fluency with Looks blocks and the paint editor

First, check out the Orange Square, Purple Circle studio link.

 

Remember, you can open the Tips Window to learn more about specific blocks or different parts of the Scratch editor.

Activity 2 Link

Reflection Prompt:

  • How did you incorporate an orange square and a purple circle into your project?
  • Where did this idea come from to you?
  • What was challenging about this activity?
  • What was surprising about this activity?

It’s Alive! Activity 3

Think of the concept of animation as looping through a series of incrementally different pictures, such as in a flipbook or claymation film. In this activity, we will use sprites and costumes, and you will practice experimenting and iterating through an animation project.

 

Activity 3 link

Reflection Prompts:

  • What is the difference between a sprite and a costume?
  • What is animation?
  • List three ways you experience loops in real life (e.g., going to sleep every night).

Debug It! Activity 4

  • In this activity you will:
    • Investigate the problem and find a solution to five debugging challenges!
    • Explore a range of concepts (including sequence and loops) through the practices of testing and debugging!
    • Develop a list of strategies for debugging projects.

Music Video Activity 5

  • By completing this activity, you will:
    • Create a project that combines animation
      and music by working on a self-directed music video
      project!
    • Gain more familiarity with sprites, costumes, and
      sounds

Music Video Activity Link

Reflection Prompt

  • What was a challenge you overcame? How did you
    overcome it?
  • What is something you still want to figure out?
  • How did you give credit for ideas, music, or code that you
    borrowed to use in your project?

Conclusion

In this lesson, you learned pulled together components from most of the scripts, used costumes to simuale actions and added sound to bring it to life. You should be begining to to get a sense of how to put a computer program together, what the main features are, and how to get things to function as group to produce a product.
