7. Wrap-up: Dance Party

Transcript

Today, you used a very important computer science concept: a forever block, or loop.

Your dance video could not have been created without them, and music in general, could not be created without the concept of a repeating loop of musical notes.

Loop statements are used everywhere, even in medical devices that save lives every day.

An ICD is an small device used by doctors and physicians to help control conditions such as sudden cardiac arrest.

This medical device uses a loop statement to constantly monitor a person’s heart rate before sending electrical pulses or shocks when it detects a very fast, abnormal heart rhythm.

In this club, you are using the Scratch programming language to build projects. Computer scientists like you use many different programming languages, but every language makes use of the repeating loop. Understanding repeating loops will make it easy for you to use them in your future computer science experiences in high school, or even when learning more computer science on your own. You'll recognize a loop no matter what programming language you use in the future.

In the next CS First club, you will make a Musical Art piece that lets someone interact with your program to play sound and music. Click the share button so others on Scratch and in our club can use your project. Then, take the Club Reflection from the Club Reflection link on this page. After finishing the club reflection, help spread the awesomeness around by writing a G+ post using the sticky note at your desk.

Write a shout out to another student, the club Guru or host for their hard work or help. Did someone have a really cool project featured in the club showcase? Write them a shout-out and let them know you think they’re awesome.

Make sure your friend gets the shout out by writing To: followed by their name somewhere on the sticky. No sticky, no pen, no problem. Just ask your Guru for one! After writing your G+ post follow your Guru’s instructions for posting it to the G+ Community page.
