Any programming language that lets users create programs by manipulating “blocks” or graphical programming elements, rather than writing code using text.

• Command

• Run Program

• Algorithm

• Block-based programming language

A sequence of steps written in a programming language that can be followed to solve a problem, especially by a computer.

• Debug

• Event

• Algorithm

• Computer Program

An error in a program that prevents the program from running as expected

• onEvent

• Bug

• Moth

• Fly in the Ointment

Statements that should only run upon a specific user action should be placed

• inside an onAction block

• below an onEvent command

• after the first programming statement

• within an onEvent programming statement

Finding and fixing problems in an algorithm or program

• Debugging

• Event Driven Programming

• Run Programs

• Algorithms

Cause the computer to execute the commands you've written in your program

• console.log

• Run Program

• Debug

• onEvent

A single instruction for the computer. Put many together and you get algorithms and computer programs.

• Algorithm

• onEvent

• console.log

• Command

A set of steps you can follow in order to solve a problem or achieve a result often written down in regular spoken language.

• Debugging

• Event

• Algorithm

• Computer Program

When the user hovers their mouse over the hawk, the

• both birds will appear only in the middle of the screen

• The sparrow will be confined to the upper right and the hawk to the upper left

• The sparrow will be confined to the lower right and the hawk to the upper left

• The sparrow will be confined to the lower left and the hawk to the upper right

Choose all the correct options. When debugging, you should

• run the program over and over, staring really hard at it

• add some console.log statements to see what is going on

• describe your program and the odd behavior to a friend

• reduce the amount of code and see if the behavior improves
