Lesson slides on Development on Technology

1. Development on Technology
A Design and Technology topic

2. Lesson objectives
At the end of the lesson, students are able to:
• Understand and apply appropriate technology to their coursework
project

3. Recall: 3 Technology topics
• Structures
• Mechanisms
• Electronics

4. Structures
• Ask yourself these questions when doing development:
• How do I make the product more stable?
• What type of reinforcements can I use?
• Are the materials used appropriate for my project?

5. Video: How to design for durability

6. Mechanisms
• Ask yourself these questions when doing development:
• Are there any motions involved in my project? (linear, rotary,
oscillating and reciprocating)
• How do I create those motions?
• Are there different mechanisms that I can use to create those
motions?

7. Video: Different ways to create linear motion

8. Video: Different ways to open a bottle

9. Electronics
• Ask yourself these questions when doing development:
• How much DC voltage is needed for the project? (Suggested
maximum voltage to be around 9V for safety reasons)
• Is it a series or parallel circuit or a combination of both?
• Can you sketch the electronic circuit diagram?
• Where can you get the electronic components?
• Can the electronic circuit work in the mock-up?

10. Video: How to solder safely and properly

11. Conclusion
• More research might be needed if a student has limited
understanding of technology
• Find out at least 3 different technology to apply to the product before
making a conclusion to how your product should work
• Justify why the technology chosen for the project is appropriate
• Apply your understanding of theory on Structures, Mechanisms and
Electronics and used the proper terms as stated in your notes.
