Technology. Technologycal processes.
What is technology?
Technology is the practical application of knowledge (science) and skills (techniques) to create solutions (technical objects or systems) wich satisfy our needs or solve our problems.
The stages of technologycal processes
Need: Analyse the need or problem and the possible constraints. Study similar cases and there solution.
The process of planning a technologycal solution
Need-Idea-Develop the idea-Construction-Check
The elements of technologycal processes are:
1.Knowledge of physycal and scientific concepts. 2.Technical drawing to transmit the idea of an object. 3.Materials and there properties. 4.Working techniques (procedures) 5.Economic considerations. 6.Information technology.
Idea: Propose one several solutions. Agree and chose the best solution.
Develop the idea: Choose the necessary touls, materials and labour. Prepare and estimate (of costs)
Construction: Construc and test.
Check: Evaluate. Write the final report.
Proposal and needs analysis
A precise definition helps you to create a specific and appropriate solution.
Now think about details: The type of bird the nest is for, its size, habits and preference, its food and its reproductive habits. ( A swallow is not the same as a stork!)
Summarise and analyse the background
Find information about previous solutions to this type of problem.
Consider technical aspects that could affect the project. (Use books, catalogues, the internet, etc.)
Clasify and select the data is more useful.
Order this information sistematically in topics.
Make a note of relevant practical details related to the data.
Desing an individual idea
Use existing models and draw possible variations to adapt them to your needs.
Explore the possibility of using new materials.
Introduce minor modifications or combine models you find interesting.
Agree and choose the best solution
You can create a table to help choose the best desing.
You can combine the positive aspects of several desings to make the definitive product.
Construction and desing
Before constructing the object, decide how to make each pice.
If something appears difficult to do, find the solution first. The problem may be more difficult to soolve later.
Drawing is the first step to building.
Draw the pices inorder you are going to make them.
Decide how to join the next pice before you draw it.
The types of drawing you can use are:
Views of the complete object.
Overhead view, side view and front view.
Details of the way pices are joined.
Separate pieces.
Process sheet - group workn plan
What you are going to do.
Who is going to do it.
How you are going to do it.
When you are going to do it.
How long it is going to take.
Important: calculate the time needed in hours and the labour costs fo a group or individual project. You can optimise the time if you plan carefully.
Prepare and estimate
Make an estimate of the construction costs in advance, then you will know weather the project is worth while.
To make an estimate, you need to know the price and quantitis of the materials you are going to use.
The price can be expressed acording to different measurments: unit, surface, weigth, length, etc. Use the appropriate measurment to calculate the price. In this example plywood measured in number of sheets, cellophane is measured in cm.
Construct and test
It is easy to make an object if the process is planed correctly. If you have a good design and plan correctly, construction will be quicker and more efficient.
Evaluate and check
Evaluation is a critical analysis of the final product to help improve it.
Appearance: Analyse the aesthetic aspects of the object.
Use: Does it work? Is it easy to use?
Materials: Are the recycable? Can you reuse them?
Durability: How long will the object last?
Maintenance: What do you need to keep the object in good condition?
Possible modifications: Based on your answer to the previous question, is there any part of the desing that you could improve?
Construction report
Front page for the project: names of the group memebers, name of the school, group, year, and title of the project.
Index: A list of the reports contents and page numbers.
Incidient report: a description of the problems you had and how you solved them.
The technology workshop
Analysing problems, thinking of ideas to solve them, discussing solutions in groups, learning about things to help us, etc.
Manual activities, e.g, cutting, gluging, sawing drilling.
This two types of activity require different spaces.
Classroom, workshop, library and store room.
Organisation of workshop spaces
The coordinator is reponsable of organaising the work of each group member to achive the teamwork. This person represents the group.
The person responsable for the materials collects the material needed for for the work and also in charge recycling leftover material.
The person responsable for the tools looks after the tools assigned to the group to make sure they are not lost or damged.
The secretary collects, checks and organaises all the written documents from each group member.
The person responsible for health and safety makes sure that the group members follow the health and safety rules in the workshop and when using tools.
The person in charge of cleanning makes sure each workstation is left completly clean.
Health and safety rules
To protect our health we have to follow rules when we are in the workshop.
Tools and machines can be dangerous if we don´t use them properly.
Safety rules prevent accidents and reduce the risk of hurting our selfs.
To prevent accidents in the workshop, you must always follow your teacher´s instructions.
Technology, society and the enviorment
Nowadays technology is present in all areas of society and has made major changes to our lives.
Sustainable development
Resources are over exploited they can run out and natural habits dissapear.
Pollluting gases are produced.
Toxic waste is produced.
