1. Introduction to Characterization


Hey! I’m Gisselle and I’m a proud Afro-Latina Googler who works with YouTube creators around the world.

In this video, I’ll give you a quick introduction to learning computer science through CS First.

You can create stories, art, animation, websites, and music… pretty much anything you can imagine with computer science.

Computer science uses code.

Code is just another way of saying “instructions for the computer.”

There are a lot of ways to write code, but in this activity, you’ll use a tool called Scratch.

Scratch is a great way to learn to code.

For this activity, you’ll use code to show details about a character, so others can get to know them.

You can create a character, add their thoughts and speech, and move them around the stage.

You can even add backdrops and sounds.

In this activity, you will imagine how a character who is missing a school assignment might act.

You’ll choose your character and use code to make your character think, speak and act in different ways to show who they are.

Then, you’ll show your story to a classmate. Your classmate should be able to describe your character based on the way that character speaks, thinks, and acts.

Let’s get started! Move on to the next video to have fun creating and coding.
