AP Computer Science Principles

In this unit, you'll learn all about digital information, how it travels on the Internet, and who owns it. You'll decide whether an athlete "owns" a tattoo or if computer-generated actors are ethical. 

The Internet seems very complex. At its most basic level, though, it is pattern of connected devices that create a network. You'll be able to create your own physical network using string and see what happens if it becomes broken at various locations.

Humans hate doing tedious tasks, but computers are great at them. How fast do you think you could count to one hundred out loud? A minute? Two minutes? Using algorithms, computers can do simple (and even complex) tasks like these in less than a second!

Part of the AP exam is called the Performance Task, in which you use JavaScript to create your own program. Some people have created a program to play cards against the computer and others have developed their own Jeopardy-like programs. What will you do?

Have you ever used Weebly, Wix, SquareSpace, or GoDaddy? These are all website development programs that have made it easy to develop your own websites, but they have their limitations. Using HTML, JavaScript, and CSS gives you the opportunity to design your website exactly how you want it. 

JavaScript can be used for more than just website building or program creation. In fact, it has a whole database of commands that can help you create images! From simple images like circles, squares, and text to more complex images like historical landmarks, JavaScript can be a drawing board for you.

The Internet is filled with data. Whenever you ask Alexa, "Alexa, what time is it?" you are both transmitting and receiving data. Data can even include private and confidential information like your credit card number or your social security number. In this unit, you will learn how to organize and sort data.

Cybersecurity is a growing field. Have you ever heard of Anonymous or Cozy Bear? The information of you or people with power are at risk whenever it is digital. After all, anything virtual can be hacked. Learn cybersecurity to discover the basics of defending yourself online.

Earsketch and E-Textiles use technology on simple household items like a radio or clothing. Whether you make your clothes glow like the image above or code with Python to create myriad sounds, technology doesn't have to be just virtual. It can be physical too.
