Design physical projects that include selection

Computing

Connecting physical computing devices

Combining outputs

Controlling with conditions

Using selection to control the flow of a program

Writing and testing algorithms

In this unit pupils will use physical computing to explore the concept of selection. Pupils will use conditions to control the flow of a program. They will make use of their knowledge of repetition when introduced to the concept of selection and write programs that utilise this concept.

Exploring selection in physical computing

a condition that always evaluates to True

a loop that repeats commands indefinitely

a part of a program where if a condition is met, a set of commands is run

if a condition is met, a set of commands is run

part of a program where commands are run multiple times in a loop

if the traffic light is green, cars can go

What is a real-life example of a condition?

a condition that checks if a button is pressed

a loop that makes a light blink five times

What is an example of repetition in a program?

the program skips the commands linked to the condition

the program repeats the commands in a loop

What happens if a condition is False in selection?

What does selection control in a program?

a loop that repeats until a condition is met

if the button is pressed, turn on the light

What is the name for the result or action produced by a program?
