a machine that converts electrical energy into mechanical energy

a chunk of code that repeatedly runs a section of the program a certain number of times

a precise set of ordered steps which can be followed by a human or a computer to do a task

Combining outputs

Computing

Connecting physical computing devices

Controlling with conditions

Using selection to control the flow of a program

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

What is a precise sequence of steps that can be followed to complete a task?

produces light when connected to a circuit

produces motion when connected to a circuit

connects to the positive side of an output

connects to the negative side of an output

What makes things move by using electricity?

connect the motor to the output pads on the Crumble

adjust the program to change the motor’s behaviour

Arrange the steps to connect a motor to a Crumble:

a sequence of instructions that repeats continually

a loop that runs a specific number of times

What is a count-controlled loop used for?
