Lesson 6 - Test - Level Crossing

Flowcharts and sequencing

Software can be used to create sequences in a flowchart, to view onscreen simulations.

Examples include:
  • Flowol
  • Logicator
  • Crocodile Clips

Basic flowchart symbols

Name Symbol Usage
Terminator

Starts or stops a process.

Input or output

An input is data received by a computer. An output is a signal or data sent from a computer.

Process

An instruction or a command.

Decision

A decision, either yes or no. For example, a decision based on temperature that turns a central heating system on or off.

Line tool

Connects the symbols. The arrow indicates direction.

Assessment - Level Crossing

Click on the button below to open the test word document

Open Flowol and the Level Crossing mimic.

Click SHOW on the mimic to reveal the mimic labels.

Watch the video to see what should happen when the Train goes around the track

Think about what decisions you need to make and the sequence of events to ensure that the train does not crash into a car or pedestrian on the level crossing.

Assessment - Tasks


  1. Fill in the Assessment Word Document.

  2. Create a suitable flowchart that controls the operation of the level crossing.

  3. Test your flowchart by running it. Does it work correctly? What else do you need to do?

  4. For extra marks use Subroutines to open and close your gates in your flowcharts.

  5. Annotate your flowchard in flowol using the text feature.

  6. FinallyScreenshot your final flowchart and add it to your word document.

  8. Save your work using your name as the file name, to the shared area /Year8 resources/you can save here/ICT/Assessment/ then into your class folder.



  • Learning Objectives

  • I can break down complex problems into smaller parts to find a solution.
  • I can develop a control solution for a system that includes a subroutine
