3. Engineering
Involves everything needed to study, design and create technological projects

4. Brainstorm ideas
New or improved technical objects arise when there exists a need to be filled
List and/or sketch all of your ideas

5. Choose the best idea Depends on the specifications/requirements
Indicated in a document containing the list of needs, requirements and constraints to respect during a project.

6. Specifications
Constraints outlined in the specifications fall under different categories
Human Constraints to do with the user
Technical Constraints function
Physical Constraints contact with natural elements
Industrial Constraints production
Economic Constraints cost
Environmental Constraints impact on the environment

7. Draw your idea Design plan  how it works and/or
Technical drawing  how its built
ALWAYS use ruler and pencil!!!

8. Design Plan
Simple diagram showing how an object will work by indicating the forces and motions that will come into play. “How does the object work?”
Contains the following:
Name of the parts
Movement of the parts
Operation forces involved
Any other useful info needed to understand how the object works
See page 257 in your workbook for an example
Complete pages in wb

9. Technical Diagram
A simplified drawing that shows the parts and materials needed to build an object. Includes how parts are linked an guided. “How do we build the object?”

10. Includes: Important shapes and dimensions to be considered
Names of parts
Materials to be used
Linking components
Guiding controls
Any other info needed to build the object
See page 260 in workbook for example

11. Materials
Raw Materials a natural substance that acts as a building block for other materials. Raw materials are transformed so they can be used to make an object.
Ex: wood, sand, sheep’s wool

12. Material: used to make an object, often comes from raw materials that have been transformed by humans.
Ex: wooden board, leather, steel
Complete pages 266 and
269.

13. Equipment
Includes all of the devices, machines, instruments, vehicles and tools used to make the object.

14. Build your technical object
Following safety workshop rules, begin building
Your idea might change as you build

15. Test your technical object
Perform tests that will determine if you have satisfied your need
Do many trials, if possible

16. Review
Can be done at anytime
Correct your design process as you go
