Today, you created your first animation.
You also learned
about an important computer science concept, loops.
Loops aren't just used to build animations.
In fact computer scientists use loops every day
in all kinds of projects.
When you set a song to play on repeat on a music player,
for example, you are using a loop.
The computer program inside the player uses a loop
to tell the song to play over and over again.
At amusement parks, almost every ride was programed
by a computer scientist using loops.
For example, this merry-go-round uses loops
since it rotates over and over again.
The Bellagio fountains in Las Vegas
were also programmed using loops.
Computer scientists wrote code
to make the fountains and lights dance to the music,
and loops made it easier for them to repeat actions,
such as shoot the water upwards.
Every time you see a piece of technology
that does something over and over automatically,
chances are a computer scientist, like you,
made that happen using loops.
Not only did you build your first animation today,
you also learned something new about
how computer science works in objects you see everyday.
Scratch is more than just a programming language.
It's a community of like-minded users
who share projects, inspiration, and encouragement.

Next time, you'll learn about art and paintings.
Then you'll use computer science to make them talk.
Until next time, have fun creating and coding.
