Design and make a warning system with two output devices (light and buzzer) that can be installed at the door and inside the room. This system should be able to tell the occupants of the room when somebody else wants to enter at the door by giving off a light and sound signal in the classroom.
Situation
The door of the Technology class is connected to the classroom by means of a long passage. It is sometimes impossible for the occupants of the room to hear when somebody is knocking at the door. Therefore is it necessary for someone to shout or hammer on the door. The teacher prefers that the door should be kept closed because pupils sometimes tamper with other learners’ products or with tools that are stored in the passage.
Analyse and write the problem down in your own words.
Research:
Make a list of existing products and solutions. Paste pictures of their appearance and cost.
Modelling:
Investigate different types of switches and make models of types that would suit to resolve the problem.
Design:
Design brief (Who? What? Where? When? Be able to?)
Specifications and constraints:
Initial designs / solutions:
Choice with reasons:
Final design (develop design and solution further):
Make:
Make a list of all the resources (tools and materials) needed. Also add the quantities or dimensions.
| Materials | Quantity/Measurements |
Draw a simple flow diagram to show the steps for making the product.(LO 7.1.3.1)
Draw a simple working drawing of your final product. Use colour, shade, thick and thin lines and shadow.
Evaluation
Product
Does the product satisfy the design brief? Explain.
Does the product satisfy the specifications and constraints? Explain.
Suggests any improvements to your final product.
Process
How well did your making compare to your planned steps?
Suggests any improvements to your plan of action.
| Learning Outcomes(LOs) |
| LO 1 |
| TECHNOLOGICAL PROCESSES AND SKILLSThe learner will be able to apply technological processes and skills ethically and responsibly using appropriate information and communication technologies. |
| Assessment Standards(ASs) |
| We know this when the learner: |
| investigates : |
| 1.1 investigates the background context, the nature of the need, the environmental situation, and the people concerned when given a problem, need or opportunity set in a local context; |
| 1.2 examines existing products relevant to a problem, situation or need. |
| 1.3 investigates by performing simple practical tests relating to aspects of the technological knowledge areas (Structures, Processing, and Systems and Control); |
| 1.4 during investigations, plans a strategy for collecting data and information. |
| design : |
| 1.5 writes or communicates a short and clear statement or a design brief for the development of a product or system related to a given problem, need or opportunity; |
| 1.6 lists product and design specifications and constraints for a solution to a given problem, need or opportunity. |
| 1.7 generates at least two alternative solutions and annotates the ideas; |
| 1.8 chooses possible solutions, gives sensible reasons for choice, and develops a chosen idea using graphics or modelling techniques; |
| make : |
| 1.9 develops a plan. |
| 1.10 chooses and uses appropriate tools and materials to make products by measuring, marking, cutting or separating, shaping or forming, joining or combining, and finishing different materials with some accuracy; |
| evaluates : |
| 1.12 evaluates the product or system based on criteria linked directly to the design brief and some of the specifications and constraints, and suggests improvements or modifications; |
| 1.13 evaluates the efficiency of the plan of action followed and suggests improving future plans. |
