Extended Quiz: Functions, Machines, and EVTOLs

In CodeHS, why do we create functions like turnRight()?

• To make our code longer

• To repeat the same code over and over

• To create shortcuts and reuse steps easily

• To make the computer run slower

Which of the following is the correct way to define a function in CodeHS?

• 
• 
• 
•

What is one advantage of using functions in your programs?

• They make your code confusing.

• You only write the steps once, then you can call the function many times.

• Functions erase your old code.

• Functions make your computer louder.

Machines and coding both use inputs and outputs. Which example shows this correctly?

• Input: Press on button → Output: TV screen turns on

• Input: pressing a keyboard key → Output: nothing happens

• Input: eating food → Output: the lights in your house turn on

• Input: CodeHS program → Output: the computer deletes itself

EVTOLs (electric vertical takeoff and landing vehicles) are being developed to…

• Replace bicycles in schools

• Fly like drones but carry people like cars

• Replace trains underground

• Make LEGO machines work automatically

Which of these is an example of input and output in an EVTOL?

• Input: pilot presses joystick → Output: vehicle tilts forward and moves

• Input: car horn honks → Output: the sky turns blue

• Input: wheels spin → Output: the vehicle eats fuel

• Input: program crashes → Output: EVTOL disappears

What is the purpose of design in engineering?

• To make random creations with no purpose

• To create something new/unique with a purpose

• To copy other people's work

• To avoid using safety measures

Which statement about design is true?

• A. Design is always done once and finished forever

• B. Design is never done; it can always be improved

• C. Design is random and has no purpose

• D. Design cannot include safety considerations

What do machines do?

• Make work harder by adding more steps

• Make work easier by changing the way force is used

• Eliminate the need for force completely

• Make random movements with no output
