ICT at key stage 3 (Year 9)
Unit 13: Control systems
Section 1: Activity 1
|
|
Objectives |
| Children should learn: |
- that control systems underlie many systems in society
- that it is possible to describe systems in a structured manner using standard conventions
- that many real-world systems focus on safety issues
|
Activities |
|
Outcomes |
|
Children: |
- Lead a discussion to:
- introduce the context
- discuss the nature and form of some different rides
- illustrate the range of issues with video
- elicit a range of issues or areas where ICT can help support the effective management and safety concerns in a theme park
- Following a broad conversation discuss the specific ride to be investigated and how safety on such rides is of vital importance. Either use a video to stimulate discussion of danger points and control that is required, or brainstorm the safety points and possible solutions, eg that the boats must not catch up with each other, or be in certain sections at the same time; that there is a requirement to be able to know where the boats are, to control their movement at certain points in the system; and that there will be rules or conditions which control parts of and the whole system.
- Introduce the pupils to the specific task using a diagram of the section of the boat ride to be investigated. After an initial discussion ask pupils to work in groups to establish and describe the processes and to identify the control mechanisms required for the section of the ride.
|
|
- describe real-world systems that have underlying complex control systems
- recognise that control systems exist to ensure people's safety
- describe the components and relationships of the system
|
|
Points to note |
- The quality of the resources illustrating theme park rides is crucial to effective analysis of the issues and systems,
eg video clips of a ride would be the best.
- Some schools may be able to make use of a school visit.
- Prepared criteria for evaluating rides would enable pupils to assess the rides.
- There are a number of theme park simulations which could provide useful additional stimulus material for this section.
- Homework could include a simple task using a worksheet, where there is a need for sense and control, which the pupils must assess using the criteria learnt during the lesson.
