Hey, and welcome to day two
of CS First fashion and design.
Today you'll create a fashion show
while you learn about an important computer science
concept called loops.
A loop, or iteration, repeats a set of instructions
over and over.
In Scratch, repeat and forever blocks are types of loops.
Any blocks you place inside a loop
will repeat a specified number of times or forever.
Check out this example of a loop in computer science.
iIlluminate lights are attached to dancers' costumes
and controlled wirelessly to match
the music and choreography.
In the video, the lights on the costumes flash
to match the music and movements of the dancers.
Computer code controls the lights using loops.
Today, you will use loops to create a fashion walk project.
In this project, the user will be able to click
on a sprite and pick a favorite costume.
Today's project will begin with a starter project.
After watching this video,
click the fashion walk starter project link
to open Scratch in a new tab.
To save this starter project to your account,
enter the sign in information from your club pass.
And click remix.
Now it's your turn.
Click on the fashion walk starter project
to open Scratch in a new tab.
Sign in with your username and password
foro your club pass.
Once you've done that,
come back to this page on the CS First tab
and click the green next arrow to move on
to the next video.
