What is the output of the program?
What is the output of the program?
What is the output of program?
When we made our (a) work we were able to move the mouse around to discover the different sounds that each color will make.
For this project we used (b) or if-then blocks that tell the computer what sound to play for each (c) .
Look at the program to answer this question. What will happen in the program when the flag is clicked?
The sprite will jump when the arrow keys are pressed
The sprite will say "Uh oh!"
The sprite will say "I'm safe!"
The sprite will say "Uh oh!" first, then "I'm safe" next
Nothing will happen
Look at the program to answer this question. When the green flag is clicked, what happens?
The meow sound plays
The meow sound doesn't play
The meow sound will play some of the times that this program is run
The meow sound plays repeatedly
Using the (a) block is one of the core ways to tell the computer how to (b) .
Computer scientists use it everyday to write code for instructions like if the Roomba vacuum robot bounces into a wall, then turn.
Or if the air hockey robot senses the air hockey puck in front of it, push it forward to knock it away.
In healthcare, dozens of small machines run simple computer programs that that instruct if a patients heart rate decreases or if the oxygen level in the person's blood drops below a safe level, then (a)
Or even logic for a machine to navigate inside a person during surgery.
If it senses something in front of it, then it turns.
(b) and computer science is all around you.
When you start recognizing it, you will realize that computer scientists make impacts (c)
No matter what field you're interested in, from music to sports to healthcare, there's a (d) innovating and improving it.
Look at the program. What causes the sprite to move?
When the arrow keys are pressed the sprite moves
When the space key is pressed, the sprite moves
When the flag is clicked, the sprite starts to move
When the sprite is clicked, it moves
In the program, what should the user do to make the Scratch cat say hello?
Press the 1 key
Press the 2 key
Press the 1 key and the 2 key at the same time
There is nothing the user can do to make the cat say hello
When we created a music video we learned about an important computer science concept, procedures.
In computer science, a (a) is a set of many instructions packaged together to create a new command.
In Scratch, the new command, or procedure, is a new custom block.
Procedures are a short way to give the computer a set of (a) and they are another way computer scientists like you (b) when (c) .
A procedure is a set of many instructions packaged together to create a (a) .
A procedure is sort of like a (b) A simple way to convey a long set of instructions to the computer with a single action.
Procedures exist in real life too. For example, you could tell someone to take one shoelace, cross it over the other shoelace, tuck it under, pull them both tight, et cetera. Or you could just say, " (c) " Which is a shorter way that gets the same result.
Raquel made this program, but when she runs it, the sprite doesn't dance. How can she change her program to make the sprite dance?
Add another change costume block to the "repeat 10" block
Attach the "dance" block below the say block
Remove the "wait 1 secs" block
Change the name of the dance block to something else
Look at the program. What happens when you click the green flag?
The sprite changes y by 100, spins 360 degrees, and changes y by -100
The sprite spins 360 degrees, changes y by -10, and changes y by 100
The sprite changes y by -10, changes y by 100, and spins 360 degrees
Nothing
In Music Video, in addition to creating a fun music video you learned an important computer science concept, (a) . Procedures make it easier read code by putting it into (b) chunks and breaking a problem into smaller pieces that can be solved individually. Complicated code and big projects like (c) are much easier when you use procedures.
Making a car drive itself is a complicated problem to solve because a car must take in a lot of (a) like the location of road edges, the presence of obstacles in the road and the locations of stop signs and traffic signals, it's a lot.
Complex problems like this are (b) for one person to solve.
So teams of (c) work together to solve them.
For example, one team of computer scientists might work on making the self-driving vehicle recognize road edges while another works on sign recognition.
