Congratulations on coding today’s computer science project! The fun isn’t over, though.

Computer scientists often continue to work on projects after the basic programming is in place, to make them more original and interesting. Now, you get the chance to do the same with add-ons. This screencast will explain the add-ons you can choose to customize your project..

Just like in the main screencasts for this project, watch the screencast first to learn how to build the add-on, then try programming it on your own. To get started, simply click on one of the add-on choices after you watch this screencast.

“Twirl Pattern” shows how to make a neat pattern with stamps “Lots of thanks makes words of different shapes sizes and colors explode all over the screen. “Bouncing and talking” creates a sprite that bounces around the screen and talks when it hits other sprites.

“Flashing text” makes text flash different colors.

“Monkey” makes a spite show up and say something, then disappear again, at different times. “Cassy dancing and talking” creates a dancing, talking sprite. “Say stuff from an array” causes the sprite to say lots of different randomly chosen things.

Before you start playing around with these add-ons, though, save a copy of your base project. Computer scientists often save copies of their projects before they tinker with them, to ensure that they can always return to a working version of their code. To save a copy, go to “file” and select “save as a copy.”

Once you have done that, take some time to explore the add-ons that interest you. If you want to continue to create and explore after today’s club is over, you can access Scratch and CS First from any computer that has access to the internet. Have fun creating, customizing, and making this project your own!

Instructions
  1. Choose an Add-On, and click "watch" to learn how to build it.
  2. Once you finish one Add-On, try another one below the video!
