Students watch the following video Made with Code: Wondagurl (1.31) and then respond to the following questions:

What is Wondagurl's career advice?

TEACHER GUIDANCE

Wondagurl uses "Mixcraft" to make her beats. Always have fun with what you are doing. Don't try to compete with the others, just enjoy doing what you love.

Mini-Lesson (5-10 minutes)

- Show students how to add the extension music commands. Review music commands with students
- Open starter project, look at the starter code for fish1, fish2, fish3 and Octopus to see examples of sequencing sounds, changing costume and looping.
- Show students how to reuse code by by dragging code from one sprite to another. video
- Show students how to name a sprite, (click on the i for information and rename) . It is good programming practice as it makes code easier to read.
- Students use handout and starter project, to build a fish choir.

Project (20-30 minutes)

Close-Out (5 minutes)

Discuss the following questions:

1. Why is a loop helpful?
2. Why should you name sprites?
3. What is a sequence?
4. Why should you change the appearance of a sprite, when clicked.
5. What was your favorite instrument sound?
