What is the definition of a Sequencing Program?
Sequencing is where the program code is executed step by step in the order it is written.

Selection is where the computer makes a decision based on an event or condition given in the code. And example of selection is ‘if else’.
What is the name of the Programming Construct where the computer makes a decision based on an event or condition given in the code?
Selection
What is the definition of an Iteration Program?

What is the type of movement when the user presses keys on the keyboard to control the sprite moving around the screen?
Key Controlled movement
What is the function of Variables?
Variables are used to store data that may change whilst the program is running. An example of this in Scratch is a score card in a game.
