Using selection to control the flow of a program

Computing

Connecting physical computing devices

Combining outputs

Controlling with conditions

Design physical projects that include selection

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

If the temperature is below 20°C, turn on the heater.

What type of loop repeatedly checks a condition?

a way to control program flow based on conditions

to check a condition and run commands if the condition is met
