6. Wrap-up: Musical Art
Congratulations on completingyour musical art interactive piece.
Musical art exhibits are displayed in placeslike malls, museums, airports,and even on the sidewalks in New York City.
You also learned one of the most importantcomputer science concepts today,the conditional, or if-then block.
Computers are great at doingthe same instruction over and overas you've seen when given a forever loopbut they can't think on their own.
They need a computer scientist like youto tell them what to do.
Most dictionaries say a robot is an automated machinethat can be programed to perform a varietyof specific mechanical functions.
Whoo, like the robotic arm up there on the signrobots are often thought of as machinesthat do jobs that are too dirty,dull, or dangerous for people.
Using the if-then block is one of the core waysto tell the computer how to think.
Computer scientists use it everydayto write code for instructions likeif the Roomba vacuum robot bounces into a wall, then turn.
Or if the air hockey robot senses the air hockey puckin front of it, push it forward to knock it away.
In healthcare, dozens of small machinesrun simple computer programs that that instructif a patients heart rate decreasesor if the oxygen level in the person's blooddrops below a safe level, then sound an alarm.
Or even logic for a machine to navigateinside a person during surgery.
If it senses something in front of it, then it turns.
If-then logic and computer science is all around you.
When you start recognizing it,you will realize that computer scientistsmake impacts all over the world.
No matter what field you're interested in,from music to sports to healthcare,there's a computer scientist innovating and improving it.
Where would you like to useyour new computer science skills?
Through your next club meetingyou will do a scratch scavenger huntwhere you can earn Scratch badgesby finding and using new blocksand functionality in Scratchwhile building a project that does whatever you want.
